More ABOUT TOPAZ…

People are often surprised to learn that topaz is actually usually brown. It is often treated to give it colour. Nowadays the most popular colour is blue, but they are also found in other colours, including pinks and purples. The blue topaz is commonly categorised in to three distinct shades: London Blue (a gray-blue), Sky Blue (a lighter blue) and Swiss Blue (a bright mid blue).

The name ‘imperial topaz’ simply refers to topaz that can range from yellow to a deep golden colour often likened to cognac and you can enjoy both to toast your 23rd wedding anniversary.

YOUR CARE GUIDE

Topaz rates 8.0 on the Mohrs hardness scale, but its toughness rating is poor due to its cleavage. High heat or sudden temperature changes can cause breaks in topaz. The gem’s colour is generally stable to light, but prolonged exposure to heat or sunlight might cause fading in yellow-to-brown, reddish brown, or dark brown topaz. Topaz is affected only very slightly by chemicals.

It’s important to avoid steam or ultrasound for cleaning topaz: warm, soapy water works best.
