About this 1.05ct lab-grown marquise diamond

This 1.05ct lab-grown marquise sits in the classic one-carat band, graded G colour (near-colourless) and VVS2 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG813615815 or 813615815. Listed at 7 retailers as of November 2, 2026, with prices from £217 to £842, a £625 spread on the same certified stone. MOH London lists it at £842. 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.
