About this 0.5ct natural radiant diamond

This 0.5ct natural radiant sits in the half to three-quarter carat band, graded I colour (near-colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 1437842598. Listed at 14 retailers as of October 29, 2026, with prices from HK$6,316 to HK$13,870, a HK$7,554 spread on the same certified stone. MOH London lists it at HK$13,870. 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.
