About this 1.56ct lab-grown oval diamond

This 1.56ct 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 LG834612610 or 834612610. Listed at 8 retailers as of October 29, 2026, with prices from £161 to £839, a £678 spread on the same certified stone. MOH London lists it at £839. 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.
