| COLOURED STONES AND DIAMOND WEIGHTS |
|
It is common practice for coloured stones including jade to be treated to enhance their appearance. This includes jade that has been bleached (usually in acid), polymer/resin filled or dyed, or a combination of any of these treatments. Prospective buyers should presume that all coloured stones sold by The Canterbury Auction Galleries have been treated unless stated to the contrary in the catalogue description. Please contact us for more information regarding enhancement and treatment of coloured stones. Any dispute as to the authenticity of a lot, including signatures, age and condition, and as to the treatment of gem stones including HTHP enhanced diamonds must be brought to our attention within TWO WEEKS of the sale date. | |
Diamond weights are gauged not weighed, and should be treated as approximate. |
