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. Hardened Gemstones is the best stimulant for the CZ Stones, which the colors are beautiful, but are cheap for the Jewelry designs.

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 Birthstone Color Loose Gemstones(CZ, Glass, Synthetic,Natural Birthstone) colors gems wholesale from China Supplier and manufacturer Birthstones: Did you know Birthstones?A birthstone is a gift of a precious material (jewelry, mainly gemstones; themselves traditionally associated with various qualities) that symbolizes the month of birth in the Gregorian calendar. It is sometimes also called birthday stone (cf. infra; but that word is, confusingly, sometimes used as a synonym for an anniversary gift, which is related to the recipient's age, that is, year of birth).Definition: Traditional birthstones:Often combined with modern birthstone lists, traditional birthstones are older society-based birthstones. Since many different cultures had their own list, jewelers' lists are often inconsistent over what constitutes a traditional birthstone. The table below contains many stones which are popular choices, often reflecting Polish tradition.[1]The Gregorian calendar has poems matching each month with its birthstone. These are traditionally the stones in English-speaking societies. It is not known whether these verses below are of the originally Gregorian calendar or not. In fact Tiffany & Co. published these poems "of unknown author" for the first time in a pamphlet in 1870.[2] Three of the verses are repeats. What’s the Difference Between Modern and Traditional Birthstones? The list of traditional or ancient birthstones most well-known in the United States actually originated in Poland between the 16th and 18th centuries. In 1912, the National Association of Jewelers released a list of so-called “modern birthstones.” The modern list differed somewhat from the traditional, most notably by including only transparent gems. Presumably, this made it easier for jewelers to create “mother’s rings,” which feature the birthstones of a woman’s children, in a manner more suited to modern tastes. (Imagine trying to create a ring with a pearl, a turquoise cabochon, and a diamond and emerald, both faceted). To this day, jewelers continue...

Synthetic Blue Sapphire Gems, Synthetic Lab Created Ruby Gems, Synthetic Alexandrite, Synthetic White Sapphire, Pink Sapphire,Synthetic Corundum Gemstones China Wholesale and Suppliers 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 comes in all colours of the rainbow but is most commonly found as opaque crystals with dull colours. Red corundum is 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: 9Specific Gravity: 3.90 to 4.05Cleavage Quality:NoneFracture: Uneven,Conchoidal Optical Properties of Corundum:Refractive Index: 1.758 to 1.780Optical 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.Dispersion:0.018 Usually, There're 3 kinds of popular Corundum Stones for Jewelry use, one is Synthetic Lab Blue Sapphire, Synthetic Red Ruby, and Synthetic Lab Alexandria Gems, The following colors are the popular color of Corundum Gemstones.

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.

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...

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...
