This 0.8ct natural heart sits in the just-under-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 2447578932. Listed at 16 retailers as of November 5, 2026, with prices from £619 to £2,120, a £1,500 spread on the same certified stone. NZ Jewellers lists it at £2,120. 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.
