This 0.81ct 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 2547545572. Listed at 13 retailers as of November 2, 2026, with prices from $1,267 to $4,305, a $3,037 spread on the same certified stone. NZ Jewellers lists it at $4,305.
