About this 0.9ct natural marquise diamond

This 0.9ct natural marquise sits in the just-under-one-carat band, graded H colour (near-colourless) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 6555474780. Listed at 11 retailers as of October 30, 2026, with prices from HK$15,473 to HK$39,521, a HK$24,048 spread on the same certified stone. NZ Jewellers lists it at HK$39,521. 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.
