About this 1.34ct lab-grown round diamond

This 1.34ct lab-grown round sits in the one-and-a-quarter to one-and-a-half carat band, graded E colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG722514138 or 722514138. Listed at 13 retailers as of October 29, 2026, with prices from £128 to £742, a £615 spread on the same certified stone. MOH London lists it at £742. 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.
