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 LG831693671 or 831693671. Listed at 6 retailers as of October 28, 2026, with prices from £252 to £1,351, a £1,099 spread on the same certified stone. Rare Carat lists it at £1,351. 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.
