This 1.01ct natural heart sits in the classic one-carat band, graded G 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 6451686176. Listed at 17 retailers as of November 5, 2026, with prices from $2,185 to $6,400, a $4,215 spread on the same certified stone. NZ Jewellers lists it at $6,400. 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.
