Yellow Sapphire Update

Wednesday, October 10th, 2012

Popular for many years, fancy color sapphires have claimed their rightful place in the world of gems. The yellow color is among the favorites, of which certain shades duplicate the desirable yellow diamond colors. Up to the late 1990’s, all yellow sapphires were either unheated or basically “just heated”. This has changed, at present, they are divided into unheated, beryllium treated and “just heated”.

As firm members of AGTA, we have an ethical obligation to always reveal the correct enhancement on any gem we sell. So we have to make sure we are fully informed of the type of treatment. We have seen that over the last few years “just heated” yellows have become scarce. The reason being that most of these yellow sapphires are cooked in the same ovens where batches of heating along with beryllium diffusion happens, thus contaminating consequent batches even if not intentionally. For stones to be truly “just heated” a single cutter needs to have processed the rough and heating themselves, in ovens never used for diffusion.

What has also changed in the present world market is the larger demand from other countries outside of the US and Europe for better, larger, quality gems. On top of that list is fine unheated yellow sapphires, particularly cherished by the strong Indian market. As prices for fine clean unheated yellows have gone up, availability on “just heated” yellows have also gone down. There still is some availability on beryllium treated stones in the market. Due to scarcity of supply, “BE” treated yellow sapphires have become more expected as the norm and accepted by the trade in general. To best reflect fair market prices on gems per their treatment, we certify all our unheated yellow sapphires to offer a confident market value to our customers.
