Listed at 8 retailers as of November 4, 2026, with prices from £2,406 to £3,213, a £807 spread on the same certified stone. Jared lists it at £3,213. 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.
