About this 1.5ct natural marquise diamond

This 1.5ct natural marquise sits in the one-and-a-half to two carat band, graded D colour (colourless) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 6551200028. Listed at 13 retailers as of November 5, 2026, with prices from HK$69,071 to HK$117,804, a HK$48,733 spread on the same certified stone. NZ Jewellers lists it at HK$117,804. 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.
