Ask the Gem Experts

Each month we answer questions from our customers. We welcome your questions and you can submit a question from our contact page.

Could you explain why blue topaz is so inexpensive compared to aquamarine which is similar colour? FH, New Zealand

Blue topaz is a very common material because it is produced by treating cheap colorless topaz with radiation. Indeed, the cost of the material is mainly in the cost of the irradiation process. The color of aquamarine is usually completely natural, and aquamarine with a fine blue color is quite rare. Hence the difference in price.


I love opal but I hear it is not durable enough for a ring. Can you advise? JB, USA

Opal has a hardness of 5.5 to 6.5, so it is somewhat soft. It can acquire scratches, but cut as a cabochon it is fairly durable. Opal is not a good choice for an everyday ring, but opal rings have been popular for centuries, so if you are careful with your opal ring and wear it on an occasional basis, it should last for a long time. A protective setting can be helpful as well.


All the best in gems,

Arnold, Rung & Ron
