means A precious gemstone, typically golden-yellow but found in blue, pink, and clear varieties, prized for its hardness and clarity.

from From Greek 'topazos,' the name of a stone said by ancient writers to come from an island in the Red Sea called Topazos — though that island's gem was likely what we now call peridot, not modern topaz. The Greek name may trace back even further, possibly to Sanskrit 'tapas,' meaning heat or fire. So the word arrived attached to one stone and quietly slipped onto another over the centuries.
