About this 1.2ct natural marquise diamond

This 1.2ct natural marquise sits in the classic one-carat band, graded I colour (near-colourless) and VS2 clarity (very-slightly-included), with a very-good cut grade and certified by IGI 809692312. Listed at 8 retailers as of October 30, 2026, with prices from HK$18,759 to HK$40,554, a HK$21,795 spread on the same certified stone. NZ Jewellers lists it at HK$40,554. 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.
