About this 0.51ct natural round diamond

This 0.51ct natural round sits in the half to three-quarter carat band, graded D colour (colourless) and FL clarity (flawless or internally-flawless), with a top-tier cut grade and certified by GIA 6551574139. Listed at 18 retailers as of October 30, 2026, with prices from £1,127 to £3,220, a £2,093 spread on the same certified stone. NZ Jewellers lists it at £3,220. 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.
