Loose Cubic Zirconia Aquamarine Pear Shape faceted cut 10x8mm stones CZ38 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 is also...

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 Nano Crystal and Nanosital gemstones wholesale from china supplier and manufacturer. What is Nano Gemstones ? A: Nanosital or 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. Nanosital or 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. Nanosital or Nano Crystal gemstone does not contain any health hazardous contaminants (lead, arsenum, cadmium) Hardness: 7 on Mohs scaleRefractive Index: 1.65-1.7Specific Gravity: 3.5-4Dispersion: 0.015Melting Point: 1700 degrees Celcius It does not change color when heated. Can be used in wax casting. The Main characteristics of Nanosital/Nano Crystal stones: 1.Nano Stone's specific gravity index is very close to that of the most valuable gemstones such as topaz, sapphire, ruby and aquamarine.2.Nano Stone and the optical properties of the most popular color gemstones are almost similar. Nano Stone's main feature is its lack of an unnaturally strong lustre, which is typical of cubic zirconia, wherein the play of colors remains attractive.3.Nano Stone's hardness (7 on Mohs scale) guarantees jewellery durability without the loss of its original look. The Nanosital hardness index (7) is higher than glass...

(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.
