This 1ct natural marquise sits in the classic one-carat band, graded I colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI 801639655. Listed at 18 retailers as of November 1, 2026, with prices from HK$17,026 to HK$42,047, a HK$25,021 spread on the same certified stone. NZ Jewellers lists it at HK$42,047.
