Topaz is a crystal that will brings out divine will. It is a stone of truth and clarity. Interestingly enough, like quartz, topaz is also piezoelectric - only a few crystals have this property.
Watch out with the big clusters as it is very light sensitive. Only the pink topaz fades in sunlight but all topaz can break into 1000 very sharp pieces when exposed to heat - so keep it in the shade.
Imperial topaz is a rare and highly prized variety of topaz known for its rich golden to reddish-orange hues, often with a pink or peach overtone. It is not the same as common yellow or orange topaz.
