Black Spinel in India

Tuesday, November 25th, 2008

Aussie Sapphire has long been a fan of Black Spinel and we take pride in being able to offer one of the largest range of calibrated sizes anywhere.  So it is always good to see others extol the virtues of this wonderful gemstone.

Came across this article in the Indian media recently which clearly outlines all the advantages of Black Spinel that we’ve been talking about for some years.  But it also had some really interesting snippets about how black gems are used in Indian culture.

The writer talks about a well-known custom in India for babies to wear bracelets on both wrists for the first year to ward off evil – the bracelets using beads of gold and black gemstones.   I have read of this custom elsewhere so it does appear to be an established custom.

He also mentions the Mangalsutra - one of the most important symbols of a Hindu marriage, traditionally worn by a married woman until her husband’s death.  The Mangalsutra usually consists of a gold ornament strung from a yellow thread, a string of black beads or a gold chain (or some combination of those elements) – it is said that the black beads are a protection from evil and so are an important part of the design.

The examples above show some great modern variations on the traditional designs – see more about this trend at this Mumbai Pluses Blog article.

Rough Gem Supply
What a difference 6 months makes!  There has been a significant shortage of rough gemstones in most catagories – this has been a gradual trend developing for a considerable time but has really started to bite since December 2008.

REASONS:  A combination of factors, most completely out of the control of the trade but some the direct fault of some in the industry.

  • Huge increases in the cost of production (fuel, electricity, parts and supplies, etc) at the same time as only modest increases in rough prices.
  • The closure by the Madagascan Goverment of exports of Rough Gems (mainly Sapphire but many others gems as well).  This is probably the biggest news in the industry for many years.  It appears all Gems are to be Cut and Heat Treated in Africa before they can leave (similar to current rules in Sri Lanka prohibiting export of gem rough).  

One must remember that this small island is probably the richest gemstone resource ever discovered and most importantly this is where the largest majority of that “CEYLON” branded Sapphire has come from for some time. 

I would like to hope this works for the financially struggling Africans on the ground but I fear that not much will change.  Already, signs are that the more powerful USA and Indian companies are trying, although with difficulty, to move their cutting operations to this country and carry on as before.

  • Enviromental and Farmers rights.  The global weather concerns and the desperate need for food production has really had major effects on production especially in China.  A good friend and major Sapphire miner Alex reports that the local farmers are not allowing them to mine on the productive river flats any longer (most of the easier river beds are already exhausted) so they are forced to mine deeper harder ground.  Mine production in China is still large but much less than even last calendar year.

More interesting Gem News:
Ruby Rumblings - The Ruby game has been in a mess for some time since the “Lead Filled” treatment became almost commonplace.  There has been mountains of Ruby in the market, mainly lower grade Indian product (often large and almost opaque) and lead filled African material.  Unfortunately for the retail customer, the altered Ruby looks very good to the eye but in my strong opinion it just “aint Ruby”!  (Oh I forgot the Berillium treated Ruby as well).

Burma Ruby Dead ?  President  Bush in his “wisdom” has banned the import of Ruby  and Jade from Burma (now known as Myanmar) into the USA starting in September 2008.  This in my opinion is a silly decision based on politics not common sense.  Although there has been a Ban in place since 2003, this latest move is supposed to tie up the loophole of Gems being processed in another country (mainly Thailand).  This is aimed at the Military Goverment but in my opinion will just hurt the individual and long suffering Burmese poor while the rich Generals will see little change.

Just how will it work?  In short it wont!  Any Ruby or Jade already in the USA prior to the cut off date can still be legally sold as Burmese.  Reports from the ground in Thailand show large US based companies pouring as much cash as they can spare into getting stockpiles into their country before the deadline.  I suppose the USA customs will now be able to tell the origin of a Gem just by looking at it.  A difficult job even for the most experienced Gem Labs.  Of course there will now be a lot of Burmese type Ruby coming from other countries or “New Finds”.

Richard Hughes changes jobs:
Richard Hughes, gemologist and author, has resigned as senior staff gemologist for the AGTA, (American Gem Trade Association) to join a jewellery TV company based in Singapore and Bangkok.  Richard has vast knowledge and experience in the Gem world - he seems to be willing to give these alternative methods of selling some support – hopefully he will bring some much needed credibility to the system.  The thought that springs to my mind though is that perhaps the old fashioned bricks and mortar Jewellery stores need to do some catching up or they might die?  Good luck Richard.

Lapidary Gear:
We have had several questions asking if Lapidary supplies will decrease in price because of our high dollar. The answer is simple Yes but No. Confused ?  I dont blame you but the simple fact is freight cost increases have wiped out in most cases more than the gain in currency exchange.  On top of this, all manufacturers face large increases on all the material they use with many increasing our buying prices.  Having said this the choice of where or what to purchase has never been better so shop around and enjoy the savings that come from competition.  We’re pretty confident you wont find a better deal than at Aussie Sapphire.  Just remember, when comparing prices, check if stock is ready to deliver immediately and if any additional costs apply – such as for 220 Volt (a common trap when buying from the US), credit card fees, foreign currency fees and charges, etc.

Tips and Tricks:

  • Need storage for your 6″ Faceting Laps, diamond saw blades, etc ? Inexpensive Size 1 padded envelopes are a cheap solution or try CD cases - ideal for your 4″ or 5″ diamond blades.  You can mark each type clearly and avoid contamination.  
  • Dull Diamond Blades – if your diamond blade becomes dull try redressing it before you throw it out. There are specific dressing sticks available but a old silicon carbide grinding wheel does the same job cheaper.  Just cut into the wheel a couple of times this removes tiny particles of metal that melt into the Diamond while cutting.  If this doesnt work then there is no Diamond left so your blade is only a drink coaster now.

New Book Section

Sunday, June 29th, 2008

We have had quite a few requests from customers asking about books on gemstones and lapidary.  After quite a search to find a good source, we are proud to announce that Aussie Sapphire now carries a range of books that will be of interest.

Please see the Books & DVD category to select from a range of lapidary books covering gem cutting, rock tumbling, jewellery making, gem collecting and more.

Handbook of Gemstones - Cally Hall    Secrets of the Gem Trade - Richard Wise  Rubies and Sapphires - Fred Ward  

These books are imported from the USA so will be ordering new stock periodically – if you are after something that is not listed, please feel free to contact us or browse the catalogues of our affiliate partner Fishpond (use the search box at the top of the list).

Book prices are extremely reasonable and they make fantastic gift ideas so please take a look at our selection.  If you are choosing for someone else, sending a gift voucher allows them to make the perfect choice.

The equipment and lapidary supplies category continues to be very popular with another Gemmasta faceting machine going out last week (replacement machine expected late this week) and lots of gem display cases, laps, tools, etc being despatched each day.  We continue to work on sourcing new products so keep an eye on this section for more bargains to come.

Have just finished another batch of sapphire cutting and in the middle of cutting some nice rough tourmaline so please contact us if you are interested in sourcing anything like this.  Mining continues to be challenging with fuel prices soaring and costs of production generally being too high for the return.  Sapphire rough is in short supply presently but we hope to list a few new pieces in the facet rough section as soon as possible.  This appears to be a general problem with very little sapphire being produced in Australia currently and similar shortages in many of the other producing countries. 

cheers for now from Aussie Sapphire

 

Minerama Field Trip Options

Thursday, February 28th, 2008

One of the most important features of Minerama is the programme of field trips.  Fossickers can visit a range of locations in the company of an experienced guide to look for a range of gems.  Heaps of fun and very affordable. 

There are field trips to suit all types of fossickers – from the complete beginner to the utterly obsessed.  See the Minerama website for more information on the program or just call in to the Minerama information desk for some guidance.

Click “Continue Reading” below to see some options for each day from Thursday 6th March to Monday 10th March 2008.

Minerama Field Trips 2008

Friday, February 8th, 2008

The draft field trip program for Minerama has just been received from the field trip convenor – John Paix.  This is a draft version; we are always dependent on good weather conditions to run these or any other trips. The weather has been cooler and wetter this summer so far and it takes very little rain to make the creeks rise and areas to become inaccessible.

See the detailed trip instructions on the website for more information.

Remember – tickets are on sale at the rear of the services club where Minerama is held from 8 am Thursday 9th. Tickets are sold on a daily basis and are not available in advance. They will cost $10 for adults and $2 for school age children this year.

Thursday 6th March.
YARROW CREEK. (Garnet Corner) Sapphire, pyrope garnet, zircon, quartz crystal. This is a location we have visited during Minerama for several years. It has yielded good results and should continue to do so for those equipped with the right tools (especially yabby pumps, long handled shovels and crowbars). Many good sapphires and garnets have come from here.

Friday 7th March.
YARROW CREEK: (The Crossing) A location not previously visited on a Minerama trip. Minerals as for Garnet Corner. The proper tools are essential here.
KINGSGATE MINES: This is a rare opportunity to visit an active mining area, courtesy of the mining company. It is the classic location for quartz crystals and bismuth and molybdenite. There will be limited opportunities for collecting. Numbers will be limited to 20.
THREE WATERS on Reddestone Creek. This is a new area for Minerama. Reddestone Creek is rich in sapphire and zircon.

Saturday 8th March.
YARROW CREEK: (The Blockup) Another location on the creek. Minerals as for Garnet Corner.
KINGSGATE MINES: As for Friday.
LONEWOOD on Reddestone Creek. The same locality as the last three years. Some very fine sapphires and zircons have been found here.
EMMAVILLE area: A visit to old mining areas near Emmaville for mineral specimens.

Sunday 9th March.
YARROW CREEK: (The Old Mine area). Another location for sapphire, zircon, garnet and quartz
TINGHA SANDS AND STANNIFER: Classic localities for rutilated quartz (grass stone) and quartz jelly beans. Approximately 80 km drive each way.

MONDAY 10th March.
BACK CREEK: (Pinkett area) An area we have not visited for several years. Quartz crystal, sapphire, zircon, topaz and black tourmaline.
PRETTY VALLEY: A location we have been visiting since 1991 and still producing sapphire, zircon, topaz and excellent quartz. Anyone can find small gems here. Limited to 25 because of the small area involved and the limited water flow in the gully.

Minerama on soon.

Thursday, January 10th, 2008

Just eight weeks to go until Minerama – the Gem and Fossicking Show at Glen Innes. This one is always very popular so get planning for a trip to the New England for hands-on fossicking and heaps of gem show bargains.

You can find more information at the Minerama Website.  The committee is still working out fine details on the field trip program but I expect the trips will be similar to last year.  Hoping to include Tingha Sands this time for the quartz crystal collectors (yet to be confirmed); The Auzex Kingsgate tour will run again with kind cooperation from Auzex Resources (a sapphire level sponsor of Minerama); Reddestone Creek at the same location as last year; Yarrow Creek locations are yet to be confirmed.  Please check the website through February for more information on the field trip program.

Dont forget that this year, scenic flights over the mining areas of Glen Innes and Emmaville will be offered by Inverell Aviation. 

Book directly with the pilot by phoning (02) 6723 1344 – flights leave from Glen Innes airport (just west of Glen Innes on the Emmaville Road) on Friday and Saturday.

Also – lots of cash and BP fuel card prizes on offer by way of a raffle, lucky door prize and lucky field trip prize draws. 

Plenty of accommodation choices in Glen Innes from luxury B&B’s to camping in the great outdoors.  You are encouraged to consider the Minerama sponsors when choosing accommodation or services in appreciation for their support.

Of course, Aussie Sapphire will be attending Minerama as a trader.  We have a great selection of products on offer – from the finest gems to gem/lapidary tools and supplies.  We have a number of new and used faceting machines/accessories in stock right now so if you are looking to upgrade or get started in the hobby, look out for the Aussie Sapphire stall inside the Services Club auditorium.

Faceting Machines

Sunday, September 9th, 2007

There are many ways to get involved in the gem hobby.  Many people start by fossicking which requires little equipment.  Once they get a collection of gems together, most start to wonder what is the next step.  We recommend that beginners to this interest consider investing in a small tumbler as this is a great way to polish up your finds and make them even more attractive. 

However, those who want to get involved at the highest level need to find a FACETING MACHINE and learn the art of gem cutting.  It’s not that hard - many learn from books/videos and there are always willing helpers to guide you along. To become an expert takes time but a novice can usually turn out their first cut Gem in just a few days.  A rewarding, and challenging pastime for young and old.

Too Many Gems!

Monday, August 20th, 2007

Of course, you can never have too many gems.  But we have a large stock of gems that we just cant seem to find time to list – this makes it a bit hard for our customers to really see what we have tucked away in the safe.

SOLUTION:  Our new “Sneak Preview” section lets us give you a taste of what we have in stock but have not yet had time to catalogue properly.  The first lot of these are some new tourmaline just finished – mixed colours (mostly pink and green with some other colours as well) and shapes (baguette, round, oval, pear, heart, square and emerald cuts).  Really pleased with how these look at a glance so can’t wait to get into them properly. 

These are individually packaged in plastic wrap sheets – lots of work to measure, photograph and describe each stone so this is just a quick snap of each sheet before we start on this big job. 

Mixed colour and size tourmaline gems from Aussie Sapphire 

If anything catches your eye, just let us know the sheet number and row/column label so we can describe and photograph it for you.

Dont worry – we are planning to get some extra help in the office starting in October so we can get these gems and many more listed properly.

cheers for now from Andrew and Leah (Aussie Sapphire

Auctions are back!

Wednesday, August 15th, 2007

It has been quite a while since we ran any Ebay auctions for sapphire rough but we thought we might put a few on just for fun.  This is a great opportunity for all cutters and collectors out there to secure some nice Reddestone sapphire at great prices. 

Check out our current auctions here.

This lot includes a few nice blues and some good parti (yellows) sapphires – photos for just two of them are included here to whet your appetite:

Blue Sapphire - Aussie SapphireParti - yellow/blue sapphire - Aussie Sapphire

It is obvious from talk around the traps that the supply of good gemstone rough is generally becoming more difficult in most markets.  There are a few reasons for this but the end result for cutters everywhere is prices are going up.  As always, you have to pay well for good rough – expecting to get the best rough for super cheap prices will most likely leave you disappointed. 

However, as a promotion, we do run these 99 cent auctions from time to time, so you might as well try your luck.  You just may get a bargain price.  Still some good rough on our main website and more to list so make sure you check these out also.

Have still got some good tourmaline rough in stock so check out these listings or contact us if you are looking for something not yet online.

Gemstone Photography

Saturday, July 28th, 2007

Gemstone photography is one of the most critical aspects of selling gems online.  While our own photography has improved markedly since starting the website, we know there is plenty of room left for improvement.  Even with the best equipment and photographic skills, this particular area is incredibly specialised and very few people can do it well. 

One of the best photographers around for this type of work is Jeff Scovil – his work is incredible and his photo gallery shows just a few examples of his work – Jeff Scovil Photo Gallery

rut_quartz.JPG

There are lots of great shots here of gemstones, minerals and the like.
One I particularly liked was this rutilated quartz from Brazil.
(copyright J.Scovil at www.scovilphoto.com)

As for our photography, we are currently using a Fuji Finepix 9500 digital camera with a Raynox DCR-250 Super Macro lens.  Camera is held steady with a heavy microscope base which allows some fine adjustment for manual focusing.  Cool white flourescent lighting is used to approximate daylight in a standardised set-up.  Even with all of this, a good shot can take many attempts and much time.  

To the casual observer, it might seem an easy job just to shoot off a few snaps but it is not unusual to spend some hours on getting a shot we are happy with.  The tiny size of a gemstone (usually much less than a centimetre) and many facets where light can reflect and glare creates a number of photographic challenges.  And just when you have the camera set up for a cut sapphire for example, switching to a rough aquamarine means adjusting all the settings.

Professional photographers who are skilled in gemstone photography are very difficult to find and justifiably charge a lot for their specialised skills.  We have made the decision to do this job ourselves so we can pass these cost savings on to our customers.  Hopefully our customers will allow for the fact that we are doing the best we can with the limited resources at our disposal.

For those interested in doing this kind of photography, be prepared for lots of trial and error.  These websites have a lot of great information that can help you get started:
