Listed at 11 retailers as of October 31, 2026, with prices from $1,170,374 to $1,518,186, a $347,812 spread on the same certified stone. RockHer lists it at $1,518,186. At this carat range, natural pricing varies dramatically across retailers, so the cross-retailer spread on this exact stone is your single best indicator of fair price.
