This 1.3ct natural marquise sits in the one-and-a-quarter to one-and-a-half carat band, graded J colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI 780669353. Listed at 6 retailers as of October 31, 2026, with prices from HK$22,297 to HK$48,404, a HK$26,106 spread on the same certified stone. NZ Jewellers lists it at HK$48,404. 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.
