About this 1.5ct lab-grown oval diamond

This 1.5ct lab-grown oval sits in the one-and-a-half to two carat band, graded E colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG838651986 or 838651986. Listed at 5 retailers as of November 2, 2026, with prices from £303 to £807, a £504 spread on the same certified stone. MOH London lists it at £807. 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.
