This 0.5ct natural oval sits in the half to three-quarter 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 2556170083. Listed at 14 retailers as of November 5, 2026, with prices from £318 to £1,321, a £1,003 spread on the same certified stone. NZ Jewellers lists it at £1,321. 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.
