About this 1.09ct lab-grown oval diamond

This 1.09ct lab-grown oval sits in the classic one-carat band, graded E colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG850690105 or 850690105. Listed at 6 retailers as of October 29, 2026, with prices from $295 to $1,208, a $912 spread on the same certified stone. MOH London lists it at $1,208. 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.
