About this 1.12ct lab-grown radiant diamond

This 1.12ct lab-grown radiant sits in the classic one-carat band, graded F colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG620498262 or 620498262. Listed at 24 retailers as of November 6, 2026, with prices from £149 to £1,442, a £1,293 spread on the same certified stone. Brilliant Earth lists it at £1,442. 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.
