About this 1.2ct lab-grown oval diamond

This 1.2ct lab-grown oval sits in the classic one-carat band, graded F colour (colourless) and VS2 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG839654906 or 839654906. Listed at 5 retailers as of November 1, 2026, with prices from £291 to £766, a £475 spread on the same certified stone. MOH London lists it at £766. 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.
