About this 1.05ct lab-grown marquise diamond

This 1.05ct 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 LG783642791 or 783642791. Listed at 20 retailers as of October 30, 2026, with prices from £134 to £844, a £709 spread on the same certified stone. Reve Diamonds lists it at £844. 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.
