About this 1.09ct lab-grown oval diamond

This 1.09ct lab-grown oval sits in the classic one-carat band, graded F colour (colourless) and VVS1 clarity (very-very-slightly-included) and certified by IGI LG778666090 or 778666090. Listed at 22 retailers as of October 29, 2026, with prices from $207 to $1,040, a $833 spread on the same certified stone. MOH London lists it at $1,040. 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.
