About this 1.12ct lab-grown oval diamond

This 1.12ct lab-grown oval sits in the classic one-carat band, graded E colour (colourless) and SI1 clarity (slightly-included), with a standard cut grade and certified by IGI LG559281159 or 559281159. Listed at 15 retailers as of October 29, 2026, with prices from £131 to £761, a £631 spread on the same certified stone. MOH London lists it at £761. 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.
