About this 0.7ct lab-grown oval diamond

This 0.7ct lab-grown oval sits in the half to three-quarter carat band, graded D colour (colourless) and SI2 clarity (slightly-included), with a very-good cut grade and certified by IGI LG407915271 or 407915271. Listed at 5 retailers as of October 27, 2026, with prices from £398 to £829, a £431 spread on the same certified stone. Yorxs lists it at £829. 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.
