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 2526003007. Listed at 5 retailers as of November 2, 2026, with prices from €841 to €1,668, a €827 spread on the same certified stone. MOH London lists it at €1,668. 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.
