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 SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 1453276340. Listed at 17 retailers as of November 2, 2026, with prices from HK$22,070 to HK$49,111, a HK$27,040 spread on the same certified stone. MOH London lists it at HK$49,111. 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.
