About this 4ct lab-grown marquise diamond

This 4ct lab-grown marquise sits in the three to five carat band, graded G colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG828680375 or 828680375. Listed at 15 retailers as of October 26, 2026, with prices from €832 to €2,426, a €1,593 spread on the same certified stone. Rare Carat lists it at €2,426. 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.
