About this 5.1ct lab-grown cushion diamond

This 5.1ct lab-grown cushion sits in the over five carat band, graded I colour (near-colourless) and VS1 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG571309475 or 571309475. Listed at 10 retailers as of October 30, 2026, with prices from €545 to €3,249, a €2,704 spread on the same certified stone. Brilliant Earth lists it at €3,249. 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.
