About this 3.13ct lab-grown marquise diamond

This 3.13ct lab-grown marquise sits in the three to five carat band, graded E colour (colourless) and VVS1 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG800656218 or 800656218. Listed at 4 retailers as of October 30, 2026, with prices from £2,926 to £5,015, a £2,090 spread on the same certified stone. Kay Jewelers lists it at £5,015. 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.
