Listed at 5 retailers as of October 31, 2026, with prices from £306 to £411, a £105 spread on the same certified stone. Blue Nile lists it at £411. 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.
