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 SI2 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 1425086456. Listed at 26 retailers as of October 30, 2026, with prices from HK$40,643 to HK$90,693, a HK$50,050 spread on the same certified stone. NZ Jewellers lists it at HK$90,693. 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.
