This 1.21ct natural oval sits in the classic one-carat band, graded I colour (near-colourless) and SI2 clarity (slightly-included), with a very-good cut grade and certified by IGI 737595428. Listed at 15 retailers as of November 5, 2026, with prices from HK$9,397 to HK$25,205, a HK$15,808 spread on the same certified stone. NZ Jewellers lists it at HK$25,205.
