About this 1.2ct natural radiant diamond

This 1.2ct natural radiant sits in the classic one-carat band, graded D colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 2446121072. Listed at 15 retailers as of November 5, 2026, with prices from HK$37,996 to HK$77,144, a HK$39,148 spread on the same certified stone. NZ Jewellers lists it at HK$77,144. 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.
