About this 0.9ct natural radiant diamond

This 0.9ct natural radiant sits in the just-under-one-carat band, graded J colour (near-colourless) and SI2 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 6401219607. Listed at 25 retailers as of October 30, 2026, with prices from HK$9,744 to HK$30,229, a HK$20,485 spread on the same certified stone. NZ Jewellers lists it at HK$30,229. 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.
