About this 4.18ct lab-grown cushion diamond

This 4.18ct 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 LG717552861 or 717552861. Listed at 12 retailers as of October 31, 2026, with prices from €528 to €2,380, a €1,852 spread on the same certified stone. MOH London lists it at €2,380. 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.
