About this 0.4ct lab-grown oval diamond

This 0.4ct lab-grown oval sits in the sub-half-carat band, graded E colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG753504663 or 753504663. Listed at 9 retailers as of October 25, 2026, with prices from $117 to $810, a $693 spread on the same certified stone. MOH London lists it at $810. 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.
