About this 1.06ct lab-grown marquise diamond

This 1.06ct lab-grown marquise sits in the classic one-carat band, graded F colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG845650882 or 845650882. Listed at 12 retailers as of November 3, 2026, with prices from £222 to £966, a £744 spread on the same certified stone. Brilliant Earth lists it at £966. 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.
