About this 3.5ct lab-grown cushion diamond

This 3.5ct lab-grown cushion sits in the three to five carat band, graded G colour (near-colourless) and VVS2 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG480177471 or 480177471. Listed at 8 retailers as of October 29, 2026, with prices from $868 to $4,620, a $3,752 spread on the same certified stone. Brilliant Earth lists it at $4,620. 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.
