Synthetic Cubic Zirconia
Synthetic Cubic Zirconia (CZ) is a hard, colorless and optical pure crystal. Because of its low cost, durability, and appearance similarity to diamond, it has been the main substitute of the diamond since 1976. CZ can make excellent transparency and colorless products. If added a small number of colored elements in the transparent CZ, colorful products can be obtained such as red, yellow, green, blue, violet, and purple products.
Corundum is an aluminum oxide with a chemical composition of Al2O3.
The corundum mixed some chromium metal inside with a deep red color is known as a “ruby.” Gemstone-quality corundum with blue color is called a “sapphire.” Colorless corundum is known as “white sapphire.” Pure corundum is defined to have 9.0 on the Mohs scale. It is a hexagonal crystal structure with 4.00 proportion.
Natural and synthetic corundum is used in a wide variety of fields because of their toughness, hardness, and chemical stability.
Spinel has long been found in the gemstone-bearing gravel.
Spinel has been a precious gem since ancient times. Because it’s beautiful and rare, it is also one of the world’s most glamorous gem. While spinel is sometimes treated as a poor imitation of ruby, individual stones can be quite valuable and may fetch high prices at the market if they are pure and have a strong, good color. Its melting point is 2135 degrees and the refractoriness is about 1900 degrees.
Synthetic Carborundum also is known as Synthetic Moissanite (chemical component SiC). Its 0.104 dispersion is bigger than real diamond (0.044), The refractive index is 2.65-2.69 (diamond 2.42).
The appearance, internal structure, and values of Moissanite are all strikingly similar to diamonds. Even using a diamond pen to test, it will also be defined as a diamond. It is difficult to distinguish them.
Moissanite has the same adamantine luster with real diamonds while the “fire” is even stronger. It is the nearest to the diamond than any other before. It shines more brightly than diamonds with only 1/10 cost of them!
Glass is a low price synthetic gems and is used to imitate nature gems & jade-like chalcedony, quartz, beryl(emerald and aquamarine), emerald, nephrite, topaz, and so on. Then the insoluble calcium compounds is formed in the glass which decides the glass is translucent or opaque.
Glass is an amorphous solid that has been around in various forms for thousands of years. Its heat transfer is slow. It’s fragile, light, and scratch easily while a low price is its biggest advantage.
Nano and natural color gems are similar in many ways. It is born with the perfect substitute of natural colored gems!
Nano can imitate almost all types of natural colored stones like topaz, garnet, emerald, and sapphire, etc for the transparency and wide color range of it.
As a rising technology, nano has unique advantages including uniform color, little color difference, heated over 1500 ℃ with stable color, easy to process, and perfect wax setting.
