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 SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 1439197082. Listed at 17 retailers as of November 5, 2026, with prices from HK$44,736 to HK$93,108, a HK$48,372 spread on the same certified stone. NZ Jewellers lists it at HK$93,108. 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.
