Listed at 7 retailers as of November 6, 2026, with prices from $2,525 to $4,600, a $2,075 spread on the same certified stone. Frank Darling lists it at $4,600. 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.
