The Egyptians believed that topaz was colored by the golden glow of the mighty sun god, Ra. This made topaz a very powerful amulet that protected the faithful against harm. The most sought after of all natural topaz is called "imperial topaz". Its rich golden color with reddish and orange overtones is generally not enhanced by any kind of treatment. The most important deposit was found in Minas Gerais, Brazil. The fine golden-yellow imperial topaz is relatively scarce.
Topaz shows pleochroism, the appearance of several colors in one and the same stone, depending on the viewing angle. Colored topaz usually gets a step- or scissor-cut. Due to its hardness (8 on the Mohs scale) imperial topaz is durable and qualifies for any kind of jewelry. Topaz is a very hard gemstone but it can be split with a single blow, a trait it shares with diamond. As a result it should be protected from hard knocks.

I have purchased gems from Gem Select twice a year, for more than a few years.Gem select is the best place to buy gems. The selection and presentation are genuine. What you see is what you get, keeping in mind the carat weight, and measurements they have listed. Never have I been disappointed with any gem I have received from them. Nan
GemSelect has a great selection of smaller cabochons. Many other retailers do not. Plus, the photo of the stone is the one you are purchasing. Shipping from Thailand is nearly as fast as from within the US. Stones are tightly and neatly packaged.
