I have a ring that was my great grandmother''s. It is a two stone ring. One stone is a CZ for sure, the other is a deep purple/wine colored stone. It''s quite possible that it is just another man made something, but has anyone ever seen one that is wine colored?
Wine coloured? Is that burgundy? Based on the fact that the other stone is a CZ, it is possible that the coloured stone is either a synthetic, amethyst or garnet.
Do you see dispersion of light (i.e. rainbow flashes, like those that you can easily see in a CZ) in this stone? If you do, it''s probably another synthetic, maybe even a CZ. I''ve seen them in many colors, and this "fire" is what gives them away easily, cause there''s no natural stone of that color that has such a high degree of dispersion.
