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 E colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 11992451. Listed at 7 retailers as of October 29, 2026, with prices from £5,125 to £9,340, a £4,215 spread on the same certified stone. MOH London lists it at £9,340. 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.
