About this 3.3ct lab-grown marquise diamond

This 3.3ct lab-grown marquise sits in the three to five carat band, graded D colour (colourless) and FL clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG821641066 or 821641066. Listed at 9 retailers as of October 30, 2026, with prices from €4,630 to €19,193, a €14,563 spread on the same certified stone. With Clarity lists it at €19,193. 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.
