About this 1.2ct natural radiant diamond

This 1.2ct natural radiant sits in the classic one-carat band, graded E colour (colourless) and SI2 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 2557492640. Listed at 15 retailers as of November 5, 2026, with prices from HK$16,490 to HK$46,656, a HK$30,166 spread on the same certified stone. NZ Jewellers lists it at HK$46,656. 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.
