About this 1.51ct natural radiant diamond

This 1.51ct natural radiant sits in the one-and-a-half to two carat band, graded H 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 1453008466. Listed at 12 retailers as of November 2, 2026, with prices from HK$35,486 to HK$78,924, a HK$43,438 spread on the same certified stone. Belgium Diamonds lists it at HK$78,924. 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.
