This 1.21ct natural heart sits in the classic one-carat band, graded I colour (near-colourless) and VVS1 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI 828654399. Listed at 18 retailers as of November 5, 2026, with prices from HK$16,890 to HK$47,369, a HK$30,480 spread on the same certified stone. NZ Jewellers lists it at HK$47,369.
