About this 1.21ct lab-grown marquise diamond

This 1.21ct lab-grown marquise sits in the classic one-carat band, graded G colour (near-colourless) and VVS1 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG494177484 or 494177484. Listed at 8 retailers as of October 27, 2026, with prices from €380 to €1,035, a €655 spread on the same certified stone. MOH London lists it at €1,035. 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.
