Our natural topazes
Topaz is a fluorine-aluminium silicate belonging to the orthorhombic crystal system. Naturally, it comes in shades ranging from pale blue to golden yellow, orange-pink and brown, although the intense blue and saturated red shades are generally obtained by irradiation or heat treatment. With a hardness of 8 on the Mohs scale, it offers excellent resistance to scratches, making it a favourite gem in jewellery, particularly for sophisticated cuts that highlight its high light dispersion.
At A&L Gemstones, we carefully select our topazes, but not all are visible on our site. Some rare and exceptional stones are only available on request. If you are looking for a specific topaz, please contact us or fill in our dedicated form.
Did you know? In the Middle Ages, topaz was often confused with other gems because of its diversity of colours. Its name is said to come from the island of Topazos (now Zabargad) in the Red Sea, although the stones mined there are actually peridots.
