About this 3.51ct lab-grown cushion diamond

This 3.51ct lab-grown cushion sits in the three to five carat band, graded E colour (colourless) and VVS1 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG768694885 or 768694885. Listed at 18 retailers as of October 31, 2026, with prices from $905 to $5,120, a $4,215 spread on the same certified stone. Brilliant Earth lists it at $5,120. 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.
