Topaz is the November birthstone and the best anniversary gemstone gift for the 4th wedding anniversary. Topaz comes in a variety of colours ranging from pink, yellow, blue, red, orange, etc., with brown being the most valuable. However; a pure topaz gem is colourless or transparent. Topaz is so rare that many people have not even seen what a real topaz appears like.
Topaz is used in jewellery items for both men and women. A real topaz is called the imperial topaz. It is available in all shapes and sizes required for making fine jewellery items. It is a hard gem similar to a diamond. This November gemstone is a symbol of love and friendliness. However, in jewellery stores, all you find is a citrine or quartz topaz which is nothing but glass.
