GIA-certified natural diamonds with a best price guarantee

We personally select every natural diamond in our range and supply it with a certificate from the GIA – the most respected gemmological laboratory in the world. We focus on the grades that make sense: F–H colour, VS1–SI1 clarity and an EXCELLENT cut – stones that are eye-clean yet sensibly priced. We buy directly from the cutting houses with no middlemen, which is why we guarantee the best price on the market.

Which colour and clarity should you choose? For natural diamonds we recommend G or H colour and VS1 to SI1 clarity – the best balance of beauty, value and price.

In response to your enquiry we will send you the GIA certificates of carefully selected natural diamonds, go through them with you in detail and help you choose the best available stone in terms of beauty, quality and price.

GIA certificate for a natural diamond – sample

Sample GIA certificate

This is what the GIA (Gemological Institute of America) certificate you receive with every natural diamond looks like. It contains the complete 4Cs – carat weight, colour, clarity and cut grade – together with the stone’s measurements and the number of the laser inscription on the girdle, by which the diamond can be verified at any time.
