Onyx is black and white banded agate (cryptocrystalline or chalcedony quartz). It should not to be confused with onyx marble, which is limestone. The banding of onyx is parallel and consistent. Some varieties of onyx differ in color, such as sard onyx, which has a brown base and white upper layer, cornelian onyx, which has a red base and white upper layer, and niccolo onyx, which has a very thin upper layer, allowing the black base color to show through as grey or blue. Onyx takes its name from the Greek word "onyx", which means fingernail; this could be due to a Greek legend, in which Eros mischievously cut the fingernails of Aphrodite with an arrowhead whilst she slept, and the gods turned the clippings into stone.
Blue topaz is the state gemstone of the US state of Texas. Naturally occurring blue topaz is quite rare. Typically, colorless, gray or pale yellow and blue material is heat treated and irradiated to produce a more desired darker blue.
