About this 1.18ct lab-grown oval diamond

This 1.18ct lab-grown oval sits in the classic one-carat band, graded E colour (colourless) and IF clarity (flawless or internally-flawless), with a standard cut grade and certified by IGI LG735573159 or 735573159. Listed at 17 retailers as of October 29, 2026, with prices from £153 to £891, a £738 spread on the same certified stone. MOH London lists it at £891. 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.
