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 IF clarity (flawless or internally-flawless), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 3555179654. Listed at 11 retailers as of October 27, 2026, with prices from HK$4,320 to HK$7,663, a HK$3,343 spread on the same certified stone. Frank Darling lists it at HK$7,663. 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.
