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,...

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.

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...

Synthetic Opal Lab Created Opal Loose gemstone wholesale from china Suppliers and manufacturer What is a Synthetic Opal? What is Synthetic Opal/Lab-Grown Impregnated Synthetic Opal? A: Among all man-made opal, lab-grown impregnated synthetic opal has the highest quality and value. It takes about a year to grow in the laboratory and is similar in properties to natural opal. Natural opal is composed of silica and water while impregnated synthetic opal contains a high percentage of silica, at least 80%. It also has the unique feature of vertical growth pattern. Lab-grown impregnated synthetic opal is a beautiful stone with perfect color vibrancy - revealing the beauty of precious opal. Other research in macroporous structures have yielded highly ordered materials that have similar optical properties to opals and have been used in cosmetics. Synthetic opals usually display a very distinctive snakeskin pattern and they show brighter colors than natural opals. The spots of color are larger but they interact with light in a very similar way to natural opals. They contain 80% of silica which is impregnated with resin. Impregnated synthetic opals look good and appeal to some but can't replace what Mother Nature creates. Synthetic solid opal can be very difficult to identify, unless you are an expert, or have a lot of experience. Look closely at the pattern - Opal created in a laboratory (Gilson opal), displays bright colours in large patches of colour. The pattern is often 'too perfect' and ordered, and can also often display a 'snakeskin' pattern. If you are still not sure, take it to a gemmologist or an opal expert. Therefore, Synthetic opals is the best stimulant for the Real Opals,and it's beautiful and brilliant for the Jewelry designs. Synthetic Opal Cabochon is one of popular shape. At Fu Rong Gems, you can Buy high...

Loose Harden Glass gemstones wholesale from china supplier and manufacturer. What is Harden Glass Gemstones ? 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.Glass-colored-Gemstones-China-Wholesale-and-SuppliersNatural 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.

Loose Natural,Semi-Precious,Genuine Gemstones Wholesale at factory prices from China Suppliers and manufacturer. What is a Natural Gemstone? A: Natural gemstones are formed in nature with no interference from humans other than being mined, cut/faceted and polished. If a stone is identified as natural, this means that it has not been treated, enhanced or altered. Faceting is allowed for a stone to still be considered natural. What is a Genuine Gemstone? (Semi-precious stones)?A: A genuine gemstone is real, but it is treated in some way to enhance its cut or appearance. Needless to say, these are also referred to as “enhanced” or “treated” stones. Why do stones get treated? Many times natural stones have discoloration, cracks and/or inclusions. Treatme nts are applied to fix these “flaws” in the stone. For example, extreme heat is applied to natural sapphires, which results in improved clarity and a more cohesive, blue color. Fun Fact:Natural, untreated sapphires are very rare and more valuable than treated sapphires. What is a Lab-Created Gemstone? A:More commonly referred to as “created” gems because it has a more positive connotation, as you probably guessed, these are made in laboratories. Other terms used are “synthetic”, “artificial”, “lab-grown” and “man-made” gems. Many of these gemstones have the exact chemical composition of the same stone created in nature (e.g. Moissanites, Lab diamond or Lab Emerald green stones.), so technically, they are still the real deal. It's now possible for the gemstones dealer to manufacture many kinds of high quality gemstones in a laboratory, including sapphire, ruby, emerald and diamond. So what does this mean for the natural gemstone business? Synthetic or lab-created gemstones are made of the same material as natural gemstones, so they share the same chemical and optical properties. A synthetic sapphire is composed of aluminum oxide, the same material as...

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...
