About this 3.05ct lab-grown marquise diamond

This 3.05ct lab-grown marquise sits in the three to five carat band, graded E colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG844607814 or 844607814. Listed at 6 retailers as of October 30, 2026, with prices from €1,403 to €5,112, a €3,709 spread on the same certified stone. Taylor and Hart lists it at €5,112. 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.
