About this 0.81ct natural radiant diamond

This 0.81ct natural radiant sits in the just-under-one-carat band, graded J 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 2444836681. Listed at 18 retailers as of October 30, 2026, with prices from HK$4,720 to HK$19,992, a HK$15,272 spread on the same certified stone. NZ Jewellers lists it at HK$19,992. 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.
