About this 1.5ct natural radiant diamond

This 1.5ct natural radiant sits in the one-and-a-half to two carat band, graded E colour (colourless) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 2161568491. Listed at 19 retailers as of October 27, 2026, with prices from £5,970 to £11,169, a £5,199 spread on the same certified stone. NZ Jewellers lists it at £11,169. 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.
