This 1.07ct natural heart sits in the classic one-carat band, graded J 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 3445115587. Listed at 19 retailers as of October 31, 2026, with prices from $2,789 to $8,104, a $5,315 spread on the same certified stone. NZ Jewellers lists it at $8,104.
