ABOUT TOPAZ
Icy blue. Honey yellow. Fiery orange. Cyclamen pink. In warm or cool tones, topaz is a lustrous and brilliant gem.
Topaz actually has an exceptionally wide color range that, besides brown, includes various tones and saturations of blue, green, yellow, orange, red, pink, and purple. Colorless topaz is plentiful, and is often treated to give it a blue color. Topaz is also pleochroic, meaning that the gem can show different colors in different crystal directions.
TOPAZ JEWELLERY
Topaz has been used for thousands of years to create striking earrings, necklaces, bracelets and cocktail rings. The bright hue of Swiss blue and striking depth of London topaz are particularly desirable, adding a vibrant richness to fine jewellery that is more affordable than many other gemstones.
To best highlight your topaz's blue tones, we recommend settings in white metals such as sterling silver, white gold and platinum. Rose gold and yellow gold will create stunning impact when paired with yellow, orange or red-toned topaz.
