About this 1.22ct lab-grown marquise diamond

This 1.22ct lab-grown marquise sits in the classic one-carat band, graded F colour (colourless) and VS2 clarity (very-slightly-included) and certified by IGI LG796601317 or 796601317. Listed at 4 retailers as of November 6, 2026, with prices from £240 to £729, a £489 spread on the same certified stone. The Diamond Guys lists it at £729. 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.
