About this 1.5ct natural radiant diamond

This 1.5ct natural radiant sits in the one-and-a-half to two carat band, graded D colour (colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 7551699481. Listed at 20 retailers as of November 5, 2026, with prices from HK$36,514 to HK$82,214, a HK$45,700 spread on the same certified stone. NZ Jewellers lists it at HK$82,214. 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.
