We issue grading and testing reports for D-Z colourless diamonds of any type (IIa, Ia, IIb, etc.) as well as for fancy coloured diamonds and even the complicated green diamond. Our reports mention authenticity, clarity treatment, and colour origin (whenever relevant and possible). 

Diamond parcels “melee”

Our melee diamond services can contain the 4cs. They include authenticity and treatment for colourless diamonds and colour origin reports for coloured diamonds. These services are available for melee of any size and shape.

Diamond Jewellery 

The setting of a diamond is no barrier to us. We offer authenticity reports for any piece of diamond jewellery, no matter the colour, shape or size. If you wish to know more about the mounted diamond, un-setting may be required for further testing.
