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 standard cut grade and certified by IGI LG821645435 or 821645435. Listed at 8 retailers as of October 25, 2026, with prices from £143 to £600, a £456 spread on the same certified stone. MOH London lists it at £600. 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.
