Mineral of the Week
#73014, Diamond (1.75 carat yellow cuttable gem-grade complex rough diamond), Sakha (Yakutia) Republic, Russia (t) $4725
News and CommentsTreating gemstones and gem minerals has been done for hundreds of years. Emeralds in antique royal European collections were oiled to enhance transparency. Rubies and sapphires have been enhanced using heat by local miners in India, Sri Lanka and Asian countries and they knew how to do this long before it was rediscovered by recent gem traders. In spite of claims to the contrary, I assume ALL tanzanite crystals were heated to improve color - untreated tanzanite crystals are gray-brown color and no collector will tolerate such poor color. So you should assume all gem crystals were treated. Does it matter? No. Treatment is inconsequential for average collectors. But if you are going to spend $30,000 or more on a gem crystal then it does matter. Treated crystals allow the average collector to obtain good quality/color gem crystals at reasonable prices. If you insist on having untreated crystals, and have each crystal certified by the Gemmological Institute of America (GIA), then the available specimens will be limited and the prices, including testing, will be expensive. So ordinary collectors should not care and should assume any gem crystal within their budget has been treated. You can start to worry about possible treatments when you hit the lottery, and start buying expensive gem crystals. John H. Betts, 7/17/2018 Click here to read past news and commentaries...
Customer Comments:"Some months ago, we asked if you could obtain for us a specimen of Fluorite from Illinois. We left you to it knowing that sooner or later you would come up with the goods. And you certainly have. It is an absolute magnificent Fluorite and we can't thank you enough for going to all that trouble to obtain it for us." Marie... "Thank you John! I just added two nice Diamonds from the North Cape Province, South Africa to my collection. John's service is impeccable! My new prized specimens were described honestly and photographed perfectly.

I look forward to my next transaction with you. "G. Tucker "I just received my order of beautiful Copper from the Ray Mine in Arizona and Native Silver with Acanthite from Batopilas, Chihuahua Mexico. Both arrived in perfect condition and I am thrilled & honored to add these awesome minerals to my Native Elements section of my collection. These beauties will add much "spice" to that group. These and all your minerals are "show worthy" pieces at bargain prices. Thank you a million times! 5 stars +++++ for this dealer!" M.P. "Thanks, John. The sapphire just arrived in fine shape. Very nice and the color and clarity were well-represented by your photographs. Another satisfied customer!" D.D.
