About this 0.5ct lab-grown marquise diamond

This 0.5ct lab-grown marquise sits in the half to three-quarter carat band, graded E colour (colourless) and VS2 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG844671591 or 844671591. Listed at 3 retailers as of October 31, 2026, with prices from £197 to £363, a £165 spread on the same certified stone. Taylor and Hart lists it at £363. 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.
