About this 1.51ct lab-grown oval diamond

This 1.51ct lab-grown oval sits in the one-and-a-half to two carat band, graded E colour (colourless) and SI2 clarity (slightly-included), with a very-good cut grade and certified by IGI LG851602943 or 851602943. Listed at 6 retailers as of October 26, 2026, with prices from $185 to $963, a $778 spread on the same certified stone. MOH London lists it at $963. 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.
