Blue topaz and aquamarine are relatively similar in appearance, however they are very different gemstones. Aquamarine is generally much more expensive than blue topaz as a result of its superior clarity and natural colour.
Blue topaz is usually treated with heat, whereas the best quality aquamarine, including the pieces which feature in our collection, are completely natural, unenhanced, and a real rarity . As a result of this, a vintage aquamarine ring is likely to sell for double the price of a blue topaz ring.
