About this 1.2ct lab-grown marquise diamond

This 1.2ct lab-grown marquise sits in the classic one-carat band, graded E colour (colourless) and VVS1 clarity (very-very-slightly-included) and certified by IGI LG794610637 or 794610637. Listed at 22 retailers as of October 27, 2026, with prices from $249 to $1,520, a $1,271 spread on the same certified stone. Brilliant Earth lists it at $1,520. 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.
