About this 0.78ct lab-grown round diamond

This 0.78ct lab-grown round sits in the just-under-one-carat band, graded E colour (colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG797609873 or 797609873. Listed at 6 retailers as of October 26, 2026, with prices from £149 to £810, a £661 spread on the same certified stone. MOH London lists it at £810. 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.
