About this 1.5ct natural radiant diamond

This 1.5ct natural radiant sits in the one-and-a-half to two carat band, graded I colour (near-colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 2507747553. Listed at 19 retailers as of October 28, 2026, with prices from HK$51,078 to HK$110,159, a HK$59,081 spread on the same certified stone. NZ Jewellers lists it at HK$110,159. 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.
