About this 1.24ct lab-grown marquise diamond

This 1.24ct lab-grown marquise sits in the classic one-carat band, graded E colour (colourless) and VS1 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG757507351 or 757507351. Listed at 16 retailers as of October 30, 2026, with prices from £144 to £834, a £690 spread on the same certified stone. MOH London lists it at £834. 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.
