About this 1.59ct lab-grown marquise diamond

This 1.59ct lab-grown marquise sits in the one-and-a-half to two carat band, graded D colour (colourless) and VS2 clarity (very-slightly-included) and certified by IGI LG787647642 or 787647642. Listed at 8 retailers as of October 30, 2026, with prices from £202 to £1,146, a £945 spread on the same certified stone. Frank Darling lists it at £1,146. 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.
