But the source of this material is man-made without any doubts nor questions!

Treatment/Scam Alert: Watermelon Tourmaline

August 23rd, 2011 No comments

A relatively new, but not brand new, fake on the market now is quartz that is cut in typical tourmaline designs and is then coated to look just like watermelon tourmaline. It is the typical CVD method used in the well known Mystic Topaz line of products. The treatment is not the problem, but that many unscrupulous vendors and dealers are selling these pieces as real watermelon tourmaline!

Gemstone Treatment Alert: Ceylon/Sri Lanka Blue Sapphires

July 6th, 2011 No comments

Please use the link below for the full story and any updates I may list as I find out more information. But a quick summation is that Sri Lanka buyers have been buying up lots of the dark dark blue sapphire rough from Nigeria and Australia and have some how discovered a way to use Beryllium Treatment to lighten these overly dark and less valuable sapphires into close to top colors and far more valuable blues! The issue is many are just being sold into the Market as Ceylon/Sri Lanka origin materials and the only treatment(s) disclosed are “Heat” or “Heat Only” or “Heated”, no disclosure of Beryllium Diffusion/Treatment disclosed!

GIA Releases a Warning in Latest G&G Issue: Trapiche Emerald Imitation

February 26th, 2011 No comments

Riccardo Befi, of the GIA Laboratory in New York, submitted the following entry to the Gems & Gemology (G&G) Lab Notes section.
Two interesting samples resembling trapiche emerald were recently brought to our attention by gem dealer Farooq Hashmi (Intimate Gems, Jamaica, New York). They had been cut from the same “crystal,” which closely resembled a natural trapiche emerald. The “crystal” was obtained on a mid-2010 trip to Colombia from a seller who was not initially aware he had acquired an imitation.

Check out the full article here: GIA G&G Trapiche Emerald Imitation

This brings yet another stone to keep an eye on! I was starting to suspect something with the sudden influx of these Trapiche Emeralds on TV Networks, Ebay, and the usual outlets that these scams typically fester and perpetrate in and then spread out from there. When a once fairly rare and expensive phenomena stone starts showing up in large amounts and on Ebay auctions for .99 starting prices with lots of them being offered and heavily discounted on TV shows, it is typically a very good flag that should set off the tingles of your spidey senses as to something being awry!

JCK Announces: Gemesis to Mass-Produce Lab-Grown/Synthetic Colorless Diamonds

December 1st, 2010 No comments

Read the article HERE

What concerns me a bit is the fact that the CEO and President of the company, Stephen Lux, is reported by JCK as stating, “the industry should not fear his product” and that he has asked for trade leaders to stop labeling his stones “synthetic.” This would lead to some serious confusion in an already confusion filled Industry! It would open up many angles for scammers and unscrupulous sellers, as well as those who just are not familiar with proper terminologies, to exploit this synthetic diamond product! After all, if it is grown in a lab by man, then it is a synthetic material, period.

Tanzanite and Other Gemstones Enhacned by Being Set with Colored Glues!

November 8th, 2010 No comments

Originally it was posted in the Aug. 3 edition of GIA’s Gems & Gemology. It was discovered that some jewelry pieces that had been purchased from one of the TV shows, name not known, had the tanzanite and amethyst glued into the bezel settings with colored adhesive/glue. It was stated that there was a noticeable color lightening once the glue was removed, especially in the amethyst.

Upon inspecting a 1.87-carat tanzanite submitted by the goldsmith, the GIA laboratory team found that a purple-colored flexible adhesive was visible on some of the crown facets, particularly at the corners. After it was removed, the color of the tanzanite appeared “very slightly lighter,” the eBrief said.

What are to expect now? Once again it shows that these TV show home jewelry network shopping shows are misleading consumers and ripping them off! Why has the Government not either forced them to comply with existing FTC Guidelines, as well as laws preventing against fraud and theft, or shut them down and brought them up on charges!!!?? Mistakes do happen, this is a given! But when these so called mistakes start piling up on a regular basis and are simple things that a trained Gemologist should be noticing if they are properly examining their products, it is a bit more then a mistake!
