About this 1.02ct natural marquise diamond

This 1.02ct natural marquise sits in the classic one-carat band, graded D colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 2556143149. Listed at 9 retailers as of October 30, 2026, with prices from HK$25,502 to HK$48,144, a HK$22,642 spread on the same certified stone. NZ Jewellers lists it at HK$48,144. 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.
