About this 1.5ct natural radiant diamond

This 1.5ct natural radiant sits in the one-and-a-half to two carat band, graded L colour (faint-tinted) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 1399367190. Listed at 8 retailers as of November 5, 2026, with prices from £1,546 to £3,232, a £1,686 spread on the same certified stone. NZ Jewellers lists it at £3,232. 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.
