A: Although not as widely used today as synthetic Corundum, synthetic Spinel is still one of the most common man-made gem materials, particularly blue synthetic Spinel. It appears frequently in class rings and costume jewelry. Blue, green and other colors of synthetic Spinel are mostly manufactured using the inexpensive flame-fusion method by which the Spinel develops around an elongated boule.

Blue Synthetic Spinels of the flame-fusion type are typically colored only by cobalt. No iron is added, and therefore they are diamagnetic, another property that distinguishes blue flame-fusion Spinels from blue natural Spinels. When viewed under the Chelsea filter and also under long wave UV light, the light blue and medium blue gems pictured below left and center show a pale pink reaction due to low cobalt content, while the dark blue gem on the right appears bright red due to much higher cobalt content.

It has retained its popularity ever since. Like the moon, this gemstone is found all over the world--from Sri Lanka, to Australia, India, Tanzania, the United States, and countries between. Moonstone was designated as the state gemstone of Florida in 1970, to commemorate the Apollo moon landings which took off from Florida's Kennedy Space Center.

Blue Color Lab Grown Diamond Oval Shaped Faceted Loose Diamonds gemstones with IGI certificate Wholesale from China Suppliers & Manufacturer PICTURES Oval cut - While reminiscent of the round brilliant cut, both in sparkle and shape, the oval Shape Gemstones maintains its own brand of elegance, and has recently become a very popular centerpiece for engagement rings. What's Synthetic/Lab Grown diamond? A synthetic diamond (also known as a laboratory-grown diamond, a cultured diamond, or a cultivated diamond) is a diamond produced by a controlled process, as contrasted with a natural diamond created by geological processes or an imitation diamond made of non-diamond material that appears similar to a diamond. Synthetic diamond is also widely known as HPHT diamond or CVD diamond, after the two common production methods (referring to the high-pressure high-temperature and chemical vapor deposition crystal formation methods, respectively). While the term synthetic may sometimes be associated by consumers with imitation products, synthetic diamonds are made of the same material as natural diamonds—pure carbon, crystallized in an isotropic 3D form. WHAT IS THE DIFFERENCE BETWEEN HPHT AND CVD? When comparing CVD vs HPHT diamonds, there is absolutely no difference other than the process used to create them. You will not be able to tell the difference between HPHT vs CVD diamonds. Both methods are capable of producing the full range and quality of real diamonds that are optically, chemically, and physically identical to earth-grown diamonds. We could dive deep into the technicalities of each method, detailing all the difference in the production process, but we believe it’s a waste of time at best and confuses and misleads people at worst. Instead, we prefer to provide you with practical and easy to follow reliable advice. As you are aware, each and every one of our lab-grown diamonds are industry certified...
