About this 0.51ct natural radiant diamond

This 0.51ct natural radiant sits in the half to three-quarter carat band, graded H colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 6551315215. Listed at 9 retailers as of November 5, 2026, with prices from HK$3,997 to HK$7,018, a HK$3,021 spread on the same certified stone. Frank Darling lists it at HK$7,018. 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.
