About this 1.23ct lab-grown marquise diamond

This 1.23ct 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 LG697512705 or 697512705. Listed at 18 retailers as of October 29, 2026, with prices from £216 to £1,081, a £864 spread on the same certified stone. MOH London lists it at £1,081. 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.
