About this 1.51ct natural radiant diamond

This 1.51ct 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 1453307957. Listed at 18 retailers as of October 28, 2026, with prices from HK$38,797 to HK$84,702, a HK$45,905 spread on the same certified stone. NZ Jewellers lists it at HK$84,702. 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.
