About this 1.21ct natural marquise diamond

This 1.21ct natural marquise sits in the classic one-carat band, graded I colour (near-colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI 809692830. Listed at 6 retailers as of November 3, 2026, with prices from HK$23,614 to HK$45,888, a HK$22,274 spread on the same certified stone. NZ Jewellers lists it at HK$45,888. 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.
