About this 1.09ct lab-grown oval diamond

This 1.09ct lab-grown oval sits in the classic one-carat band, graded D colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG829618903 or 829618903. Listed at 8 retailers as of November 4, 2026, with prices from $583 to $1,581, a $998 spread on the same certified stone. MOH London lists it at $1,581. 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.
