About this 1.18ct lab-grown marquise diamond

This 1.18ct lab-grown marquise sits in the classic one-carat band, graded E colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG733574293 or 733574293. Listed at 17 retailers as of November 2, 2026, with prices from €195 to €1,447, a €1,251 spread on the same certified stone. Brilliant Earth lists it at €1,447. 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.
