About this 1.02ct lab-grown oval diamond

This 1.02ct 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 LG831692128 or 831692128. Listed at 8 retailers as of October 29, 2026, with prices from £193 to £1,032, a £838 spread on the same certified stone. Reve Diamonds lists it at £1,032. 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.
