About this 0.51ct natural radiant diamond

This 0.51ct natural radiant sits in the half to three-quarter carat band, graded E colour (colourless) and IF clarity (flawless or internally-flawless), with a top-tier cut grade stated by the retailer rather than the lab and certified by GIA 2557513756. Listed at 12 retailers as of November 2, 2026, with prices from £530 to £1,313, a £783 spread on the same certified stone. MOH London lists it at £1,313. Flawless clarity in sub-one-carat stones is rarely visible to the naked eye over VS1, so you are paying a meaningful premium for grade rather than appearance.
