Product introduction

Opals are a Chrysoberyl mineral in the Chrysoberyl family. Chrysoberyl is beryllium aluminum oxide with chemical molecular formula BeAl2O4. It belongs to the rhombic system. The crystal form is usually short columnar or platy.

Strictly speaking, "cat's eye" is not the name of a gem, but rather an optical phenomenon that appears on certain gems. Namely ground into a hemispheric gem with strong light irradiation, the surface will appear a thin and narrow bright reflection, called "cat eye flash" or "cat eye live light", and then according to what the gem is named, if the gem is quartz, called "quartz cat eye", if it is emeralds, then called "golden green cat eye". May have cat eye flash gemstone kind is very much, according to statistics may amount to 30 kinds, the more common on the market besides quartz cat eye and gold green cat eye, basically still have "pyroxene cat eye", "aquamarine cat eye" and so on. Because the golden green cat eye is the most famous and the most precious, it is also used to be referred to as "cat eye", other cat eyes can not be called so.

Cat eye: An opal made of artificial fiberglass and available in brown, blue, and red.

But the artificial opal appears 2-3 bright bands at the top of the arc at the same time, while the natural opal only appears one bright band. Using a magnifying glass, it can be seen that the artificial opal has a hexagonal honeycomb structure with a low hardness of about 5, a small density of 2.46 g/cm3 and a refractive index of 1.44
Opal is a kind of precious gem. Its quality is mainly determined by color, eyeliner, weight, etc. The following are briefly described:

1. Color: There are a variety of cat eye colors, mainly yellow with other tones

2. Eyeliner: Eyeliner should be straight and even, continuous and continuous, clear but not cloudy, bright but not dark;

3. Weight: For gemstones, the greater the weight, the more their value will increase geometrically. For cat eyes, it is no exception, there are few on the market, and those with diameter greater than 5cm are even less common.

Notes:
Due to the light and screen setting difference, the item's color may be slightly different from the pictures.
Please allow slight dimension difference due to different manual measurement.
