About this 1.02ct lab-grown marquise diamond

This 1.02ct lab-grown marquise sits in the classic one-carat band, graded G colour (near-colourless) and VS1 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG844672367 or 844672367. Listed at 16 retailers as of October 26, 2026, with prices from £245 to £662, a £416 spread on the same certified stone. MOH London lists it at £662. 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.
