Mozambique ruby has made a big impact on the market. Unheated material is now in abundance with plenty of really fine material available For many buyers the Burmese material has taken a back seat. For the Chinese market especially, the Mozambique material is preferable as there is much mistrust of anything that has been “treated” – even if just heat treated as is the case with much of the Burmese material.

Again, the mistrust of treated gemstones in China is making the market price of emeralds certified with “no oil” or “insignificant oiling” soar as they are very hard to find.
Stones certificated as having “moderate” or “significant oiling” are of no interest to the Chinese buyer but still acceptable to the European and US markets where oiling has been recognised as a long established, acceptable form of treatment.
Aquamarine – The fine quality dark aquamarine we used to see from localities such as Brazil and Madagascar was almost none existent on the market. The pale Nigerian material was almost all that was being offered, some of it almost too pale to be described as aquamarine.
Large good quality sapphires were readily available with some very fine Sri Lankan stones being offered , several 50ct+ fine clean examples were viewed – nice to see but a little big for most hands!
Strangely the very dark mid blue sapphire material was demanding higher prices than the pale-ish Ceylon material. Again an effect of demand in the Chinese market, maybe mirroring the 1980’s UK retail market when dark, even black sapphire was being touted as the higher quality material to a public that didn’t know better.
A new stone is currently been advertised to the trade and public . Csarite - a colour change diospore currently only found in the Anatolia region of Turkey. The stone exhibits a range of colours under different lighting conditions from soft green to raspberry purplish pink. Some stones also exhibit a chatoyant effect when suitably cut.
