About this 1.2ct lab-grown oval diamond

This 1.2ct lab-grown oval sits in the classic one-carat band, graded E colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG815649523 or 815649523. Listed at 6 retailers as of October 29, 2026, with prices from £259 to £876, a £617 spread on the same certified stone. MOH London lists it at £876. 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.
