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 SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 2145970060. Listed at 24 retailers as of November 2, 2026, with prices from HK$66,025 to HK$125,122, a HK$59,097 spread on the same certified stone. NZ Jewellers lists it at HK$125,122. 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.
