About this 0.5ct natural marquise diamond

This 0.5ct natural marquise sits in the half to three-quarter carat band, graded H colour (near-colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI 810634454. Listed at 16 retailers as of November 1, 2026, with prices from HK$5,917 to HK$20,197, a HK$14,280 spread on the same certified stone. NZ Jewellers lists it at HK$20,197. 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.
