About this 1.1ct lab-grown oval diamond

This 1.1ct lab-grown oval sits in the classic one-carat band, graded H colour (near-colourless) and SI1 clarity (slightly-included), with a standard cut grade and certified by IGI LG459193909 or 459193909. Listed at 4 retailers as of November 2, 2026, with prices from £244 to £732, a £488 spread on the same certified stone. MOH London lists it at £732. 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.
