About this 1.2ct natural marquise diamond

This 1.2ct natural marquise sits in the classic one-carat band, graded J colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI 780669590. Listed at 7 retailers as of November 5, 2026, with prices from HK$15,479 to HK$40,817, a HK$25,338 spread on the same certified stone. NZ Jewellers lists it at HK$40,817. 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.
