This 4.15ct 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 LG844629527 or 844629527. Listed at 7 retailers as of October 29, 2026, with prices from €1,516 to €3,509, a €1,993 spread on the same certified stone. Cape Diamonds lists it at €3,509. 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.
