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 VS1 clarity (very-slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 6451130406. Listed at 22 retailers as of October 30, 2026, with prices from HK$43,671 to HK$98,068, a HK$54,397 spread on the same certified stone. NZ Jewellers lists it at HK$98,068. 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.
