Black Double Star Sapphire Oval Cabochon Natural Thailand Gemstone 38.90 carat
This handsome and unique gem is a black Thai double star Sapphire from Ban Katcha village near the Cambodian border in Thailand. It is unusual compared to other star Sapphires as it contains Hematite as well as Rutile which gives the stone a golden black color with the main star being light yellow and the secondary star being a light blue. These are natural stars, not diffused. Each star has six rays yet the light blue star is faint and thus is difficult to see well. The stars are perfectly overlapped so when one looks closely it is noticeable that the rays of the blue star fall directly centered between the rays of the yellow star. They are nicely orientated to the center of the gem and the phenomenon in general is medium high in brightness. This beauty is an oval cabochon that measures 20.2 x 15.1 x 10.6 mm that weighs 38.90 carat. This is an unheated, opaque gem with only very minor flaws such as color zoning, surface naturals and hairline fissures. Overall, this gem has a very fine appearance in hand. With a hardness of 9 on Moh’s scale, Corundum is suitable for most any type of jewelry. Cabochons are exceptionally resistant to wear due to the deflective shape thus this gem will make an excellent everyday gents ring. Sapphire is the birthstone of September.
Re-sizing or re-building to another size with the same gemstones is free!
Re-sizing one of our rings can often be done quite easily by hammering and re-polishing when only increasing by a size or so and there will be no noticeable delay in the shipping time. When we need to have the size decreased at all or increased by more than about one size then I have to ask you to be patient as it will need to re-enter the queue and will be ready for shipping in about 30 days. Right after you make the purchase be sure to message me about the new size before I have a chance to ship.
Thailand’s Gem Markets
Being a gemologist in Thailand makes providing you with the right gemstones a snap. Furthermore, the gem markets here are nothing short of amazing! We shop in four different gem districts across the country and the variety is world class. Additionally, a precision gem cutter is working for our operation. Of course, we also source fine gemstone rough with our worldwide network of contacts in the mining business.
Since I love to travel and shop for gemstones, I do act as a buyer’s guide to the gem markets for any visitor that would like assistance. Often I can meet you at a gem market or even pick you up at the airport to get our adventure started.
Custom cut gemstones
An essential part of our service is custom gemstone cutting. You may supply rough stones for us to have precision faceted or cabbed into the shapes that you desire. In addition, many gemstones that are already native cut will be improved in clarity and light return by a new precision cut.
Custom orders on gemstone cutting are normally ready in just two to three weeks. Message me with details of your gemstone requirements. I will provide the address along with special instructions on shipping stones to us.
