About this 1.17ct lab-grown oval diamond

This 1.17ct lab-grown oval sits in the classic one-carat band, graded D colour (colourless) and SI1 clarity (slightly-included), with a standard cut grade and certified by IGI LG530208304 or 530208304. Listed at 16 retailers as of November 1, 2026, with prices from $227 to $1,085, a $858 spread on the same certified stone. MOH London lists it at $1,085. 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.
