About this 5.31ct lab-grown marquise diamond

This 5.31ct lab-grown marquise sits in the over five carat band, graded D colour (colourless) and VVS2 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG843655298 or 843655298. Listed at 15 retailers as of October 31, 2026, with prices from £1,337 to £5,061, a £3,724 spread on the same certified stone. Michael Trio lists it at £5,061. 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.
