About this 1.27ct lab-grown marquise diamond

This 1.27ct lab-grown marquise sits in the one-and-a-quarter to one-and-a-half carat band, graded E colour (colourless) and VVS2 clarity (very-very-slightly-included), with a standard cut grade and certified by IGI LG818649156 or 818649156. Listed at 22 retailers as of November 4, 2026, with prices from £153 to £900, a £746 spread on the same certified stone. Reve Diamonds lists it at £900. 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.
