About this 0.51ct natural round diamond

This 0.51ct natural round sits in the half to three-quarter carat band, graded H colour (near-colourless) and FL clarity (flawless or internally-flawless), with a top-tier cut grade and certified by GIA 2538759424. Listed at 9 retailers as of October 30, 2026, with prices from €913 to €2,412, a €1,499 spread on the same certified stone. NZ Jewellers lists it at €2,412. 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.
