Loose Cubic Zirconia Champagne Light Shade Rectangle Double checkerboard Cut 9x6mm stones CZ12 wholesale from China Manufacturer and Suppliers Pictures What is Cubic Zirconia? A: Cubic Zirconia (or CZ) is zirconium oxide (ZrO2 ), is widely synthesized for use as a diamond simulant and it is a lab made created stone with a specific gravity of between 5.6-6.00 and at about 8.5 hardness on Mohs scale, which is harder than most natural gems. Its refractive index is high at 2.15 - 2.18 (B-G interval) and its luster is very good. Its dispersion is very high at 0.058 - 0.066, exceeding that of diamond (0.044). Cubic Zirconia Gemstones is the best stimulant for the Real diamond, it's beautiful and brilliant for the Jewelry designs. At FU RONG GEMS, you can Buy White and Colored CZ Loose Cubic Zirconia Stones With Quality Grades A to Top Grade Quality AAAAA at Wholesale Direct Factory prices from the Real China Professional Manufacturer and Suppliers. How Loose Cubic Zirconia Quality is Determined? A: There are four main factors that help determine the quality or grade of cubic zirconia. These are carat (or carat weight), clarity, color, and cut. CZ stones are imitation diamonds or simulants and are measured in carat weight. Loose cubic zirconia stones are always heavier than real diamonds. This is because the materials that are used to create the stones are denser. Though loose cubic zirconia stones are generally colorless, many shades of colors can be added using trace elements during the manufacturing process. These colors might include lavender, peridot, pink, violet, champagne, aqua, citrine yellow, and others. Typically, transparent cubic zirconia will be the more valuable, high-end diamond imitation. Colored CZ stones are valued according to the rarity, evenness, and tone of their colors. Clarity, or clearness, of loose cubic zirconia...

Loose Moissanite Oval Faceted Brilliant Cut 9x11mm stones wholesale from China Suppliers & Manufacturer PICTURES VIDEO  What Is Moissanite? Moissanite was first discovered in trace quantities that were carried to Earth from a spectacular meteorite. Possessing fire, brilliance, and luster far greater than that of a diamond, Moissanite stones sparkles unlike any other gemstone on earth. Composed of carbon and silicon, Moissanite is also one of the hardest and toughest known elements on earth, making it extremely resistant to scratching, chipping and breaking. Its durability and incomparable beauty make it an ideal center stone for an engagement ring or jewelry gift. Moissanite Diamonds come in many fancy shapes and sizes and can be used to create a one of a kind Moissanite Ring or used in other unique Moissanite Jewelry. Moissanite Optical Properties: Moissanite's characteristic sparkle is more than just a show of beauty - it's a testament to the superior science behind the jewel, boasting more fire, brilliance and luster than any gemstone on earth. This is not merely a sales line, but a scientific and quantifiable fact. Moissanite is known for its high refractive index of 2.65, which is notably higher than diamond, sapphire, CZ and other gemstones known to be very brilliant. Brilliance is the flashes of white light exiting the top and sides of a gemstone. The higher the refractive index of a gemstone, the more brilliance the jewel emits. Moissanite's superior refractive index makes Moissanite the most brilliant fine gemstone on earth. Moissanite's fire, the flashes of colored light, is even more impressive, being more than twice that of a diamond. Luster is the amount of light that is reflected back to the observer from the surface of the gemstone. In addition to superior fire and brilliance, Moissanite has 18% greater luster than a...

Loose Lab grown Created Synthetic Diamonds CVD or HPHT Diamonds Gemstones Wholesale from China Suppliers and Manufacturer What's Synthetic 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 Are CVD Diamonds? A CVD or Chemical Vapor Deposition Diamond, also referred as a laboratory-created Diamond, is produced by means of a synthetic method, as compared to real or Natural Diamonds, which are generated by physical processes. In addition, CVD Diamonds started appearing in the gemstone Diamond market many years ago. This process involved bringing a gas like methane into a vacuum chamber and then activating and breaking down the molecules of the gas with microwaves, which causes the carbon atoms to accumulate on a substrate like the way snowflakes accumulate in a snowfall. What are the Methods to create the CVD Diamonds? There are now mainly two methods of manufacturing CVD Diamonds, the first is the HPHT or High Pressure High Temperature process and the other is CVD or Chemical Vapor Deposition. The HPHT method was used to successfully grow Diamonds in 1956 by General Electric, and basically mimics the natural process. The HPHT process and the energy and equipment needed is costly and produces Diamonds with mostly...

Loose Spinel Gemstones: Aquamarine,London blue, Tourmaline Green gemstones wholesale from China Supplier 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. This is the only gem material of any kind...

(Transparent Series) (The rough is produced by another rough manufacturer) Page 01 Page 02 Page 03   What is Hardened Glass Gemstone?A: Glass is an amorphous form of silica (with various percentages of additives) that has been used as a gemstone for millennia. Clear glass for gems is man-made, formed by fusing silica sand with various additives at temperatures of 1000+°C.Natural glasses include obsidian, which is is a rapidly quenched lava, and closer to pure silica glasses, such as libyan desert glass.A unique man-made glass, although not often used in gems for obious reasons, is trinitite, a mildly radioactive glass formed from the fusing of sand by the detonation of the first atomic bomb in 1945.Common glass has poor dispersion and refractive index, however it is very cheap to manufacture and is known in jewellery terms as paste - often backed with metal foils to increase brilliance. Hardened Gemstones is the best stimulant for the CZ Stones, which the colors are beautiful, but are cheap for the Jewelry designs. Contact us for the further information if you have questions.

CORUNDUM COLOR CHART 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 gold. Corundum comesin all colours of the rainbow but is most commonly found as opaque crystals with dull colours.Red corundumis called ruby, blue corundum is called sapphire, and all other colours are called fancy sapphires. Some varieties of corundum will fluoresce under short wave and long wave UV light if there is enough chromium in the crystal structure but little iron, which tends to quench any emitted energy. Physical Properties of Corundum: Mohs Hardness: 9 Specific Gravity: 3.90 to 4.05 Cleavage Quality:None Fracture: Uneven,Conchoidal Optical Properties of Corundum: Refractive Index: 1.758 to 1.780 Optical Character: Uniaxial/- Birefringence 0.007 to 0.010 Pleochroism Dichroism: blue - violet-blue and greenish-blue; green - yellowish-green; yellow - pale yellow; purple - violet; orange, yellowish-red - deep crimson.
