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 16 retailers as of October 30, 2026, with prices from $912 to $4,861, a $3,949 spread on the same certified stone. Brilliant Earth lists it at $4,861. 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.
