This 1.01ct natural heart sits in the classic one-carat band, graded I colour (near-colourless) and SI2 clarity (slightly-included), with a top-tier cut grade stated by the retailer rather than the lab and certified by GIA 5191662130. Listed at 19 retailers as of October 30, 2026, with prices from €1,025 to €3,330, a €2,304 spread on the same certified stone. NZ Jewellers lists it at €3,330. SI-grade stones are eye-clean roughly 60 to 70% of the time at this carat range. Check the inclusion plot on the cert and ask the retailer for high-resolution video before buying.
