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 1568428839. Listed at 32 retailers as of November 5, 2026, with prices from HK$45,512 to HK$100,522, a HK$55,011 spread on the same certified stone. NZ Jewellers lists it at HK$100,522. 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.
