About this 1.01ct lab-grown marquise diamond

This 1.01ct lab-grown marquise sits in the classic one-carat band, graded F colour (colourless) and VS2 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG831618674 or 831618674. Listed at 17 retailers as of November 4, 2026, with prices from £116 to £780, a £665 spread on the same certified stone. Reve Diamonds lists it at £780. 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.
