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 SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 7568727567. Listed at 12 retailers as of October 30, 2026, with prices from HK$3,374 to HK$14,020, a HK$10,647 spread on the same certified stone. NZ Jewellers lists it at HK$14,020. 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.
