About this 1ct natural radiant diamond

This 1ct 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 1455156310. Listed at 16 retailers as of October 30, 2026, with prices from HK$28,033 to HK$55,508, a HK$27,476 spread on the same certified stone. NZ Jewellers lists it at HK$55,508. 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.
