About this 1.2ct lab-grown marquise diamond

This 1.2ct lab-grown marquise sits in the classic one-carat band, graded E colour (colourless) and VS2 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG845650813 or 845650813. Listed at 10 retailers as of October 28, 2026, with prices from £152 to £853, a £701 spread on the same certified stone. Reve Diamonds lists it at £853. 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.
