Cat's Eyes - Just A Couple of Variants
Nothing much really, just a couple of variants of cat's eyes - with copyright-free (a rarity: possibly rarer than the cats eyes themselves, really) pictures that I found over at Cochise College. But before we go to the variants, let us start with a few basics regarding cat's eyes.
True cat's eyes are varieties of chrysoberyl, and are valuable gemstones. It's (chrysoberyl's) chemical composition is BeAl2O4 (i.e. Beryllium Aluminium Oxide). They can come in a range of colours between yellow, green and brown.
A large part of a cat's eye's value is judged from its richness of colour, sharpness and clarity - especially that of its inside band. For example, a cat's eye with a sharp, straight and brilliant inside band is considered more valuable than one with a fuzzy inside band.
Now, back to our two variants:
Remember, chrysoberyl cat's eyes are the true cat's eyes. Apatite may appear to be similar to chrysoberyl, but it is actually a softer and less valuable stone. Other chrysoberyl cat's eye substitutes include quartz and glass.
