Loose Spinel Aquamarine Blue Light Color #104 Round Shape Faceted Cut 6mm Gemstones wholesale from China Supplier and manufacturers. Pictures 106# blue color stones usually used as the simulated color of Aquamarine Color Gemstones. What's Synthetic Spinel? 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. These flame-fusion Spinels can be distinguished from natural Spinels by a slightly elevated refractive index due to a chemical variation involving higher aluminum content. 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. None of the synthetic Spinels shown below contain enough cobalt to cause magnetic attraction.

Lab Grown Diamond Pear Shaped Faceted D E F Color Loose Diamonds with IGI Certificate Wholesale from China Suppliers & Manufacturer PICTURES Video:   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 by leading certifiers, therefore when choosing your diamond, solely focus on trying and go for as high of colour and size as your budget allows it.
