Blue Topaz

Blue topaz rivals Aquamarine in colour and charm

Found in greater abundance, it offers superb clarity and luminous colour at a fraction of the cost. Used as a central focus or combined with other gems, Blue topaz appeals to all market segments, especially as blue is the colour most favoured by population.

There is an exceptionally wide range of colours in the topaz range other than blue, they include; brown, green, yellow, orange, red, pink and purple. Colourless topaz is also another option.

Topaz is one of the US birthstones for November (the other is citrine)
