This 4.5ct lab-grown marquise sits in the three to five carat band, graded E colour (colourless) and VS2 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG833652726 or 833652726. Listed at 6 retailers as of October 28, 2026, with prices from €1,224 to €4,905, a €3,681 spread on the same certified stone. Rare Carat lists it at €4,905. 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.
