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 CVD HPHT Blue And Pink Color Gemstones Wholesale from China Suppliers & Manufacturer Lab Grown Pink Diamonds - are these real diamonds? Extremely high quality, real diamonds are now being grown in various labs around the world. True Pink lab grown diamonds are rare as it's hard to do Pinks even in the lab, but our lab grown Pink diamonds are the real deal - real, 100% Pink Diamonds. These will test positive as diamond in *any* diamond test - because they are 100% real pink diamonds, simply grown above the Earth's surface instead of below the Earth's surface. Of interest, there are two ways to grow lab diamonds: 1) replicating the high pressure temperature that occurs under the Earth (known as HPHT) and 2)replicating the extremely low pressure of outer space in a lab (there a lot of diamonds in outer space btw!) - this is known as CVD. Most lab grown diamonds are white or yellow or blue. Our lab grown pink diamonds are rare even in the lab grown diamond world, and are 100% real diamond. pink diamonds can be grown using both of the above processes, as both produce real diamond. Our pink lab diamonds are graded at independent diamond grading labs like any other mined diamond. The difference is they were formed in a lab rather than under the Earth's surface. Their pink color is naturally part of the diamond itself, and comes from the secondary step of exposing it to additional high pressure. These are not 'coated' pink diamonds, the color is atomically part of each diamond itself. Where can I buy a real lab grown Pink Diamond? As noted, true lab grown pink diamonds are hard to come by but we specialize in Pink Diamonds and have a number of...
