About this 1.02ct natural marquise diamond

This 1.02ct natural marquise sits in the classic one-carat band, graded J colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI 803629414. Listed at 17 retailers as of November 5, 2026, with prices from HK$12,179 to HK$33,090, a HK$20,910 spread on the same certified stone. NZ Jewellers lists it at HK$33,090. Cut grade matters more than carat or clarity for visible brilliance. If you can shift budget toward an Excellent or Ideal cut, do it before chasing higher colour or clarity.
