About this 1.51ct natural radiant diamond

This 1.51ct natural radiant sits in the one-and-a-half to two carat band, graded D 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 1226247495. Listed at 30 retailers as of October 30, 2026, with prices from HK$56,866 to HK$128,316, a HK$71,451 spread on the same certified stone. NZ Jewellers lists it at HK$128,316. 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.
