Is a topaz considered a gem?

Answer 1

Yes, topaz is a gem. It is an interesting one because it can be found in many different colors including clear or transparent, yellow, grey, blue, pink (rare), gold, and red. Many people buy "blue topaz" thinking they have the real thing, but it not that common to find naturally occuring blue topaz. Instead, the lighter shades of topaz can be heated to produce a blue tone.
