C. Dunaigre Reports
Over the past years, C. Dunaigre Reports have gained worldwide recognition and acceptance on all the major markets. They are perceived as documents providing a truly independent & professional third party opinion on any gemstone submitted for analysis.
Not being involved in the buying, selling or appraising of Gem Material allows us to provide unbiased, precise and concise information about a gemstone being tested to the final client in a readable format. We specialize in the analysis of coloured gemstones and report on various aspects of that gemstone such as identification, treatment and most probable geographical origin.
It is important to note that due to the similar geological settings found at the various mining sites of different countries, there may be an overlap in the gemmological properties of gemstones from different geographical origins. We may therefore not always be in a position to come up with a statement on the probable provenance of the item being tested.

Gemstone Reports
The Gemstone Report is designed to offer all relevant information on the gem material being tested. This includes weight, measurements, shape & cut, colour, identification, and treatment. An opinion on the most probable geographical origin is also being given, whenever possible, for natural rubies, sapphires, emeralds, spinels, Chrysoberyls, Tanzanites, Tzavorites, Opal and Paraiba tourmalines.It is important to note that due to the similar geological settings found at the various mining sites of different countries, there may be an overlap in the gemmological properties of gemstones from different geographical origins. We may therefore not always be in a position to come up with a statement on the probable provenance of the item being tested.
Any relevant additional information regarding the gemstone is addressed as a footnote at the bottom of the Report (see sample Reports).
Note that the Report is a statement of the condition of the Gemstone at the time of the examination only and will therefore not reflect subsequent changes that may be made to that gemstone after its examination and reporting. Also note that we do not report on loose diamonds and pearls.
