This 0.81ct natural oval sits in the just-under-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 2566578137. Listed at 13 retailers as of October 30, 2026, with prices from £525 to £2,200, a £1,675 spread on the same certified stone. NZ Jewellers lists it at £2,200.
