Identification of crystal technical standards
Currently commercially available hydrothermal synthesis Amethyst, technology is already very mature production technology due to rising production costs continue to decrease, access to markets of high-quality Synthetic Amethyst growing number of natural and synthetic Amethyst Amethyst is the identification of Buy Amethyst jewelry, when the major concern.
From the exterior view, the general synthetic amethyst color tone is extremely homogenous, unlike the natural amethyst will exist different shades of color changes, but differs from the color tone can not serve as the sole basis for identification. In accordance with its inclusion, ribbons and other internal characteristics in order to make an accurate identification.
Synthetic Amethyst Freshwater pearls contained in the gas-liquid inclusions and the color distribution less uniform, while the color of natural amethyst is the flaky distribution was flat. Synthesis of large volume colorless crystals may contain sub-Jingjing nuclear. Other features of synthetic and natural Amethyst Amethyst same can not be detected by conventional means to find its differences with the natural crystal.
Amethyst crystal clear, color, dignified and generous, very suitable for knowledge and women's wear, ring bordered an Amethyst, giving added a bit solemn and elegant.
Notes
Natural gems are mostly formed by the color, nature is very stable, but the purple amethyst is not its most stable state, in the long-term exposure under high-temperature baking, or legs when the Amethyst easy to color, even become a more stable light yellow to yellow . Therefore, wear and collectors should avoid high temperature and exposure.
Quality requirements and technical standards
Identification of crystal technical standards are as follows:
Color: Light purple profound
Luster: vitreous luster
Cleavage: None
Fracture: conchoidal
Mohs hardness: 7
Density: 2.66 (+0.03, -0.027) g/cm3
Optical characteristics: non-homogeneous body, a-axis crystal, Masamitsu, there has been bovine intervention Pearl bracelet
Zoom examination: ribbon, liquid and gas-liquid two-phase inclusions, gas, liquid, solid three-phase inclusions, needle-like rutile, tourmaline, and other solid mineral inclusions, negative crystal and so on.
