About this 1.09ct lab-grown marquise diamond

This 1.09ct lab-grown marquise sits in the classic one-carat band, graded F colour (colourless) and VVS1 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG844657530 or 844657530. Listed at 17 retailers as of November 1, 2026, with prices from £191 to £946, a £756 spread on the same certified stone. Brilliant Earth lists it at £946. 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.
