About this 1.01ct lab-grown oval diamond

This 1.01ct lab-grown oval sits in the classic one-carat band, graded E colour (colourless) and FL clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG816615866 or 816615866. Listed at 18 retailers as of October 29, 2026, with prices from £193 to £1,870, a £1,677 spread on the same certified stone. Brilliant Earth lists it at £1,870. 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.
