About this 1.51ct natural radiant diamond

This 1.51ct natural radiant sits in the one-and-a-half to two carat band, graded F colour (colourless) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 6445035342. Listed at 11 retailers as of November 4, 2026, with prices from HK$20,965 to HK$46,911, a HK$25,946 spread on the same certified stone. MOH London lists it at HK$46,911. 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.
