About this 3.5ct lab-grown cushion diamond

This 3.5ct lab-grown cushion sits in the three to five carat band, graded E colour (colourless) and VS2 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG821658145 or 821658145. Listed at 17 retailers as of October 27, 2026, with prices from $539 to $6,100, a $5,561 spread on the same certified stone. Brilliant Earth lists it at $6,100. 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.
