Diamonds
Buying a loose diamond is a different exercise from buying a finished ring. You are judging the stone on its own merits before any setting flatters it. People come to Hatton Garden for this exact reason: to compare individual stones, source a centre for a commission, or match a diamond to a piece they already own.
Reading a stone properly
The 25 dealers and jewellers listed in this category supply individual diamonds across the popular cuts, round brilliant, oval, emerald, cushion and princess, with more unusual shapes turning up depending on stock. The thing that separates a good purchase from a regret is documentation and plain talk. A reputable seller will walk you through the 4Cs, show you the inclusions under magnification rather than glossing over them, and hand you an independent grading report, commonly from GIA.
- Is there an independent lab report, and from which laboratory?
- Natural or lab-grown, and are there any treatments or enhancements?
- What is the fluorescence, and how do the proportions actually measure up?
- What are the returns terms, and how is the stone insured in transit?
Coloured diamonds are around too, though supply and price swing widely with colour and intensity, so treat those as a special order. Once you have settled on a stone, the same street can set it, certify it or value it. Compare the listings below, then book a viewing to see your shortlist in daylight.
