About this 1.5ct natural radiant diamond

This 1.5ct 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 standard cut grade stated by the retailer rather than the lab and certified by GIA 6405174570. Listed at 19 retailers as of October 30, 2026, with prices from HK$58,450 to HK$131,172, a HK$72,722 spread on the same certified stone. NZ Jewellers lists it at HK$131,172. 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.
