About this 1.31ct natural radiant diamond

This 1.31ct natural radiant sits in the one-and-a-quarter to one-and-a-half carat band, graded D colour (colourless) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 3505747015. Listed at 12 retailers as of November 4, 2026, with prices from £3,071 to £6,173, a £3,102 spread on the same certified stone. MOH London lists it at £6,173. 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.
