About this 1.08ct lab-grown marquise diamond

This 1.08ct 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 LG848690404 or 848690404. Listed at 10 retailers as of November 4, 2026, with prices from £179 to £981, a £802 spread on the same certified stone. Brilliant Earth lists it at £981. 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.
