About this 1.24ct lab-grown oval diamond

This 1.24ct lab-grown oval sits in the classic one-carat band, graded G colour (near-colourless) and VVS1 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG830620330 or 830620330. Listed at 8 retailers as of October 30, 2026, with prices from £188 to £1,067, a £880 spread on the same certified stone. Brilliant Earth lists it at £1,067. 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.
