About this 1.5ct natural radiant diamond

This 1.5ct natural radiant sits in the one-and-a-half to two carat band, graded I colour (near-colourless) and SI2 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 2557877387. Listed at 18 retailers as of November 5, 2026, with prices from HK$22,650 to HK$52,393, a HK$29,743 spread on the same certified stone. NZ Jewellers lists it at HK$52,393. 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.
