About this 0.99ct lab-grown marquise diamond

This 0.99ct lab-grown marquise sits in the just-under-one-carat band, graded E colour (colourless) and VVS2 clarity (very-very-slightly-included), with a standard cut grade and certified by IGI LG654401065 or 654401065. Listed at 17 retailers as of October 28, 2026, with prices from £139 to £814, a £675 spread on the same certified stone. Reve Diamonds lists it at £814. 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.
