About this 0.64ct natural marquise diamond

This 0.64ct natural marquise sits in the half to three-quarter carat band, graded G colour (near-colourless) and I1 clarity (included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 6193059985. Listed at 2 retailers as of November 1, 2026, with prices from HK$5,641 to HK$7,807, a HK$2,165 spread on the same certified stone. Rare Carat lists it at HK$7,807. 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.
