Read our commitment →We do not list run-of-mine goods. What you read on the list is what we hold in stock, and there is only one quality level.
Extra white, the top of the scale. We never go below F, not even on melee: that is what keeps a pavé consistent.
VVS1, VVS2, VS1, VS2. No SI or lower stone enters our stock, including the smallest sizes.
Proportions, polish and symmetry checked stone by stone. Anything below Very Good is set aside.
Fourteen cuts, all held in permanent stock, from melee sizes to centre stones.
For every size: the average weight per stone, the number of stones per carat, the price per carat and the price per stone. Enough to cost a complete piece without calling us. Any special shape is also cut from your drawing, from 1 to 150 mm.
