About this 0.5ct natural marquise diamond

This 0.5ct natural marquise sits in the half to three-quarter carat band, graded D colour (colourless) and SI2 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 6531371102. Listed at 22 retailers as of October 30, 2026, with prices from HK$3,849 to HK$15,613, a HK$11,764 spread on the same certified stone. NZ Jewellers lists it at HK$15,613. 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.
