About this 0.8ct lab-grown round diamond

This 0.8ct lab-grown round sits in the just-under-one-carat band, graded D colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG480148000 or 480148000. Listed at 5 retailers as of November 2, 2026, with prices from £200 to £772, a £572 spread on the same certified stone. MOH London lists it at £772. 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.
