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 5556456772. Listed at 18 retailers as of October 28, 2026, with prices from HK$23,700 to HK$62,823, a HK$39,123 spread on the same certified stone. Queensmith lists it at HK$62,823. 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.
