About this 1.09ct lab-grown marquise diamond

This 1.09ct 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 LG605350969 or 605350969. Listed at 28 retailers as of October 30, 2026, with prices from €226 to €1,144, a €917 spread on the same certified stone. Reve Diamonds lists it at €1,144. 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.
