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.

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...

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...
