About this 3.4ct lab-grown cushion diamond

This 3.4ct lab-grown cushion sits in the three to five carat band, graded I colour (near-colourless) and VS1 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG557237384 or 557237384. Listed at 9 retailers as of October 31, 2026, with prices from €557 to €4,413, a €3,856 spread on the same certified stone. Do Amore Diamonds lists it at €4,413. 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.
