This 0.8ct natural heart sits in the just-under-one-carat band, graded I colour (near-colourless) and SI1 clarity (slightly-included), with a top-tier cut grade stated by the retailer rather than the lab and certified by GIA 2537907559. Listed at 18 retailers as of October 30, 2026, with prices from £472 to £2,032, a £1,560 spread on the same certified stone. NZ Jewellers lists it at £2,032. 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.
