About this 1.2ct natural radiant diamond

This 1.2ct natural radiant sits in the classic one-carat band, graded I colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 3565124196. Listed at 14 retailers as of October 30, 2026, with prices from HK$17,858 to HK$40,454, a HK$22,597 spread on the same certified stone. NZ Jewellers lists it at HK$40,454. 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.
