About this 0.7ct lab-grown oval diamond

This 0.7ct lab-grown oval sits in the half to three-quarter carat band, graded E colour (colourless) and SI2 clarity (slightly-included), with a very-good cut grade and certified by IGI LG407915274 or 407915274. Listed at 11 retailers as of October 26, 2026, with prices from £370 to £1,234, a £864 spread on the same certified stone. Friendly Diamonds lists it at £1,234. 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.
