Noah's gemstone statue

A statue encrusted with topaz, rubies, sapphires, and tourmaline

Topaz was a gemstone.

In the holodeck adventure Julian Bashir, Secret Agent, Bashir, posing as geologist Patrick Merriweather, had his knowledge of gemstones tested by Hippocrates Noah, showing him a statue encrusted with various kinds of gems, including topaz. Bashir successfully surmised that the statue contained not only topaz, but rubies, sapphires, and tourmaline, as well. (DS9: "Our Man Bashir")
