About this 1.5ct natural radiant diamond

This 1.5ct natural radiant sits in the one-and-a-half to two 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 7501718262. Listed at 23 retailers as of October 30, 2026, with prices from HK$18,641 to HK$49,561, a HK$30,920 spread on the same certified stone. NZ Jewellers lists it at HK$49,561. 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.
