About this 1ct natural radiant diamond

This 1ct natural radiant sits in the classic one-carat band, graded D 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 2556353422. Listed at 16 retailers as of November 5, 2026, with prices from HK$12,438 to HK$35,245, a HK$22,807 spread on the same certified stone. NZ Jewellers lists it at HK$35,245. 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.
