Limitation of Identification Service

Treatment identification is obtained based on the current knowledge at the time of examination. Results given for the same item may lead to different results with continuing research. Often, gemstones (example, yellow sapphires) are irradiated to modify / improve the colour. Irradiation is unidentifiable by the current gemmological tests and hence, its presence or absence will not be indicated on the IIGJ-RLC identification reports. Colour of certain stones (example, orange –yellow sapphires) may fade with the time. IIGJ-RLC Jaipur shall not be held responsible for any compensation if the colour of stones (including sapphires) fade after the certification. In certain cases, because of the lack of evidence / characteristic features in the samples or lack of some specific equipment, the sample may be returned without any identification report. IIGJ-RLC Jaipur in routine employs non-destructive methods of identification, however, in certain cases destructive methods shall be employed on the permission of the Customer / depositor.

OTHER GEMSTONES

Most of the gemstones such as aquamarine, chalcedonies, feldspars, quartzes, tanzanite, tourmaline, topaz, spodumene, etc. are heated or irradiated to produce commercially important colours. These treatments are currently unidentifiable by gemmological analyses, and hence, IIGJ-RLC reports do not comment anything about presence or absence of such methods. However, such stones are considered for disclosure for fissure filling, impregnations, dyeing or coating.
