Earth mined Topaz. Possible irradiation treatment . Irradiation occurs naturally to cause color in Topaz, but is also a safe and accepted treatment on most topaz on the market today. Blue topaz directly from the ground is very rare, so I always assume all topaz has been irradiated. This very deep colour of blue is known as London Blue.
If you wish, we can have a retail replacement appraisal done by a master valuer for an additional $50. If our price does not beat his appraisal by at least 40%, we will adjust the price so it does. BUT. We never charge you more if the appraisal is higher than anticipated.
