Loose nano crystal Garnet red #1607 Round Shape Faceted cut 4mm gemstones wholesale from china supplier and manufacturer. Pictures What is Nano Gemstones ? A: Nano Crystal gemstone - is the glass-ceramic material with nano sized (10⁻⁹m) crystals of Spinel in an aluminosilicate glass matrix, which is not special glass and it is not synthetic crystal or mineral - it is their hybrid. This composite material has unique physical and optical properties: Color (homogeneous and even), Density (3-3.3g/cm³), Luster (RI=1.61-1.64); Melting temperature (more than 1650 C°) and high thermal shock resistance make this material ideally compatible with the wax-casting technology. Nano Crystal gemstone are a new type of created gemstone made especially for jewellery. The colour is homogeneous, meaning that if you bought 100 emerald green nano crystal stones, the colour would be exactly the same in every stone. The material has been created with precious metal clay in mind, so any size gem should be kiln safe and blow torch safe with out colour change or damage. #Nano Crystal gemstone# does not contain any health hazardous contaminants (lead, arsenum, cadmium) Hardness: 7 on Mohs scale Refractive Index: 1.65-1.7 Specific Gravity: 3.5-4 Dispersion: 0.015 Melting Point: 1700 degrees Celcius It does not change color when heated.

Loose Synthetic Lab Created Corundum Blue Sapphire 34# Round Shape Step cut Thailand cutting 8mm Gemstones Wholesale from China Suppliers and manufacturers. --Also Called as Synthetic Blue Sapphire,Lab created Blue Sapphire.--We Supply and Manufacture Corundum Blue sapphire stones in All kind of popular Shapes and Sizes;--Color Shades: #33 Light shade, #34 Medium and # 35 dark blue. Pictures What's the Blue Sapphire Color Stone? Blue sapphire belongs to the mineral species corundum. It can be a pure blue but ranges from greenish blue to violetish blue. The name “sapphire” can also apply to any corundum that’s not red and doesn’t qualify as ruby, another corundum variety. Sapphire is the September birthstone and for the 5th and 45th anniversary gemstone gifts. For specific birthstone information, September birthstone, Sapphire comes in all colors except red! It may be colorless, a deep blue, green, golden yellow, pink, reddish-orang, and violet. The most valuable color of sapphire is referred to as "corn-flower blue;" black, grey, or green overtones to this vivid blue will reduce overall value. Blue sapphire is not as expensive as diamond, emerald, and ruby, with the exception of the rare variety called Padparadscha, an orange-pink stone, and some Pink stones. The most common Corundum colors are Blue Sapphire and Ruby color stones, but we can also supply White Sapphire, Orange Sapphire, Yellow Sapphire and Alexandrites in all shapes and sizes. We have quite a collection of Blue Sapphire Color Loose gemstones such as popular Round Brilliant Cut,Princess Cut,Emerald Cut,Cushion Cut and also unique heart, Oval,Octagon,Marquise, Pear,Star Cuts and Much More...

It has a hardness...

Loose Aquamarine blue Spinel 108# Round faceted 2mm and 3mm gemstones wholesale at factory price from China Supplier and manufacturer. Pictures 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. Blue Spinel gemstones manufactured by the slower and more costly flux-grown method have a vivid blue color due to high cobalt content. They are generally small in size, faceted from small synthetic crystals that are shaped like natural octahedral Spinel crystals, as opposed to the large rounded boule shapes of flame-fusion Spinels. Because the major chemistry is the same as natural Spinel, the refractive index range is also the same. While the common flame-fusion synthetic blue Spinels are almost always diamagnetic, flux-grown blue Spinels are weakly magnetic due to their higher cobalt content....

True synthetic alexandrite itself is rarely seen because it is much easier to create synthetic corundum and synthetic spinel with color change properties that look like alexandrite. Synthetic corundum changes from a purple resembling amethyst under artificial light to a greyish-blue in daylight where synthetic spinel more closely resembles alexandrite with its change from reddish to blue-greenish hues. (There is also genuine color-change sapphire which mimics alexandrite, as well as color-change garnet that can be a real fooler.) The most common Corundum colors are Blue Sapphire and Ruby color stones, but we can also supply White Sapphire, Orange Sapphire, Yellow Sapphire and Alexandrites in many kinds of popular shapes and sizes.

What is Corundum and What are its Basic Qualities?A: Corundum is an aluminum oxide that commonly forms hexagonal barrel-shaped prisms that taper at both ends or as thin tabular hexagonal plates. It has a hardness of 9 on the Mohs scale, making it one of the most durable commercial gemstones. It has no dominant cleavage and fractures in a conchoidal manner. A high density of ~4.0 g/cm3 (most silicate minerals are ~2.6 g/cm3) results in corundum occurring in secondary placer deposits and recoverable by panning methods, similar to how you would recover placer...

Lab Grown Pulled Czochralski Blue Sapphire Loose Lab Royal Blue Sapphire Gemstone wholesale from china Suppliers and Manufacturer. What's Pulled Czochralski Blue Sapphire Gemstone? Flame fusion creates long, tear-shaped pieces of synthetic corundum. Consisting of a mix of aluminum oxide and chromium, would have yielded a synthetic ruby. Another melt process, the Czochralski process, uses radio waves to melt the aluminum oxide. A rod tipped with a seed crystal is inserted into the mixture and slowly rotated and pulled out, creating a column of sapphire. The lab created Blue Sapphire can also be created by flame fusion but the quality and resemblance of synthetic Blue Sapphire created by Czochralski Pulled process is considered to be the best and superior to all other lab created Blue Sapphire. As It follows the same process as natural Blue Sapphire is created make it the most superior among other Blue Sapphire. Natural Blue Sapphire are rare and over-valued. It is better to buy synthetic Blue Sapphire made by Pulled method as they have exact same chemical composition and physical composition and are sold at fraction of price of natural Blue Sapphire. They also appear brighter and more vivid than natural Blue Sapphire making it the better than corundum blue sapphire stones. SYNTHETIC Blue Sapphire (Pulled Czochralski) PROPERTIES： Chemical Formula:Al2O3 Hardness: 9 Luster-Subadamantine To Vitreous Stability:Very Good Fracture:Conchoidal Refractive Index:1.762-1.77 Lab Created Pulled Blue Sapphire looks exactly like natural Blue Sapphire. Only when observed under high magnification microscope in labs, small bubbles or foreign particles can only differentiate between them. How Can Gemologists Distinguish Lab-Grown Sapphires From Natural Sapphires? Distinguishing lab-grown sapphires from natural sapphires is challenging, but each artificial creation method leaves telltale signs that an expert gemologist can identify. Melt processes like flame fusion may create sapphires that exhibit curved growth lines and...
