Imitation Rocks – Imitation Gems Explained

Each object is rarely attractive market for a long time before being copied or imitated. Gems have worked at least 6000 years by a truth in the material described as imitations can be blended with coal or synthetic materials.

Imitation jewelry such as stone, but is usually very different in their composition and optical properties and physical properties. May be natural or artificial mineral substances with similar color to the stones to be desired. Glass is a favoritestimulants used to mimic many different gemstones, because it can in almost all colors and is molded or cut to size is done. Most of glass is much softer than the stones that imitate and are badly chipped with wear. It may also contain bubbles and get a syrupy consistency characteristic Swirly. Glass is deflection alone, with a refractive index between 1.5 and 1.7, not only refractive gem minerals that fall into this range.

The most common diamond simulatelast 20 years is cubic zirconia, as originally manufactured for use in laser and electronic research. More recently, synthetic Moissanite has been on the market. With their high refractive index and the fire is difficult to detect by visual text alone. CZ from diamonds can be distinguished by its lower reflectivity and thermal conductivity. Vapor pressure is measured with a thermal probe.

Introduction In the last 1990 years, a synthetic moissanite SiC is a new synthesisGemma with properties close to diamond than any other imitation. With a hardness of more than 9 degrees on the Mohs scale, it is harder than ruby, sapphire, or any other jewel except diamond. However, there is a large visible difference in these diamonds and Moissanite index of refraction only index of double refraction. As a result of a doubling of the aspects pavilion on the stones can be large can be seen. However, it is difficult to recognize, without the use of instruments in which the stones are very smalland set in jewelry.
