About this 0.68ct lab-grown round diamond

This 0.68ct lab-grown round sits in the half to three-quarter carat band, graded E colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG711531154 or 711531154. Listed at 14 retailers as of October 30, 2026, with prices from £85 to £666, a £581 spread on the same certified stone. MOH London lists it at £666. 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.
