This 1.01ct natural cushion sits in the classic 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 3545376007. Listed at 13 retailers as of November 4, 2026, with prices from £650 to £1,602, a £952 spread on the same certified stone. MOH London lists it at £1,602. 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.
