Over the past several months, due to various enhancements amongst various colored stones, the demand for untreated or unenhanced stones has increased. If a stone is in fact unenhanced, there can be no question as to what treatment has or hasn’t been applied to it. However, pending on what type of gem we’re talking about, these are more or less common-and priced accordingly.

I came across some piece of information that said if you wish to tell if an aquamarine is heated or not, a gemologist with a standard loupe can tell. If you’re very lucky, and/or you’re looking at a rough specimen, that may be one thing.

The other bad news is, if you want something natural, and good, anymore you’re going to pay for it if it’s of quality and pending the size and specifics.

Natural opals anymore have become quite expensive pending on the exact type. Yes, there is more than one type of opal. Pending what kind of opal it is, and it’s particulars, you will pay more or less for it. They were quite popular during the 1980’s as they have a myriad of colors which fit into the outrageous trends of the time. So suddenly they became popular, and they were relatively more affordable than they are now. The demand increased, the mines in Australia are simply not producing as much material. The strength in the Aussie dollar against the US dollar forced a doubling in the prices alone, so something had to give. That something was the quality and the rise of synthetics with the exception of certain higher end jewelers.

I’ve always been a fan of the more unusual stones, and things you don’t ordinarily see. The illustration below is a natural opal showing no evidence of enhancements that was purchased from AJS Gems. This is a 0.97 carat trillion cabochon magnified 45x.
