About this 0.85ct natural marquise diamond

This 0.85ct natural marquise sits in the just-under-one-carat band, graded I colour (near-colourless) and SI2 clarity (slightly-included), with a very-good cut grade and certified by IGI 502165563. Listed at 13 retailers as of October 30, 2026, with prices from HK$6,186 to HK$20,345, a HK$14,159 spread on the same certified stone. NZ Jewellers lists it at HK$20,345. 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.
