what is the chrysoberyl
Since chrysoberyl is a very hard and tough gemstone, it is a natural constituent of alluvial, deposits in areas in which pegmatite dikes are found. Sources and Recovery Methods Despite the fact that chrysoberyl is a comparatively rare mineral, it is found in a number of places in the world, in two or three of which fine gem qualities are mined. Gem material is almost invariably recovered from alluvial gravels, rather than being mined from primary deposits.
