Garnet identification method: There are very few imitations of garnet. It's easy to tell. Identify the garnet mainly from the following four points:
1, garnet if the color is super bright and ultra-transparent, if the price is very attractive, leisurely, there are problems.
2, look at the cotton wool impurities, garnet is easy to have black spots, ice cracks.
3, garnet is heavier than the general crystal, take it under the hand, if it is lighter than the powder crystal, it is necessary to be vigilant.
4, the garnet is more delicate, the surface feels very slippery, feels very comfortable and very oily feeling ~ and there is a feeling of cold in the hand, the heart of the people, not the "glass" feeling of powder crystal.
Gemstones similar to garnets include rubies, red spinels, and the like. Ruby is a heterogeneous body with dichroism, characteristic chromium absorption spectrum, obvious fluorescence reaction, and can have a flat ribbon. The needle-like inclusion can form an angle of 120°; the refractive index of the spinel is low. Fluorescence reaction, visible octahedral inclusions. Garnet is homogeneous and has no dichroism. It has no reaction under Charles mirror and can have a horsetail-like inclusion.
The high quality water calcium aluminum garnet is bright green and very similar to jade. The water calcium aluminum garnet often has black spots with a refractive index of 1.73, and the red zone has no characteristic absorption.
