About this 0.5ct natural marquise diamond

This 0.5ct natural marquise sits in the half to three-quarter carat band, graded I 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 3495457549. Listed at 15 retailers as of October 30, 2026, with prices from HK$4,323 to HK$14,688, a HK$10,365 spread on the same certified stone. NZ Jewellers lists it at HK$14,688. 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.
