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 very-good cut grade stated by the retailer rather than the lab and certified by GIA 6411268329. Listed at 24 retailers as of November 5, 2026, with prices from HK$69,988 to HK$126,057, a HK$56,069 spread on the same certified stone. NZ Jewellers lists it at HK$126,057. 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.
