About this 1.29ct lab-grown oval diamond

This 1.29ct lab-grown oval sits in the one-and-a-quarter to one-and-a-half carat band, graded E colour (colourless) and FL clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG818653734 or 818653734. Listed at 19 retailers as of October 29, 2026, with prices from £188 to £2,380, a £2,193 spread on the same certified stone. Brilliant Earth lists it at £2,380. 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.
