About this 0.51ct natural heart diamond

This 0.51ct natural heart sits in the half to three-quarter carat band, graded I colour (near-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 7546085420. Listed at 14 retailers as of November 6, 2026, with prices from €401 to €1,125, a €724 spread on the same certified stone. MOH London lists it at €1,125. 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.
