About this 1.09ct lab-grown marquise diamond

This 1.09ct lab-grown marquise sits in the classic one-carat band, graded E colour (colourless) and IF clarity (flawless or internally-flawless) and certified by IGI LG783642363 or 783642363. Listed at 22 retailers as of November 1, 2026, with prices from £195 to £1,035, a £841 spread on the same certified stone. Reve Diamonds lists it at £1,035. 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.
