F SI1 Natural Diamonds

F colour SI1 clarity is an unusual but effective combination — pairing colourless appearance with a budget-friendly clarity grade. This appeals to buyers who prioritise colour purity above clarity, knowing that a well-chosen SI1 diamond can be completely eye-clean.

F colour ensures the diamond appears perfectly white in any setting, while SI1 clarity offers significant savings over VS grades. The key is selecting an SI1 stone where the inclusions are located away from the table facet and masked by the diamond's brilliance.

Our gemmologists specialise in finding these "best of grade" SI1 diamonds — stones that perform visually like VS2 but price like SI1.
