About this 3.15ct lab-grown cushion diamond

This 3.15ct lab-grown cushion sits in the three to five carat band, graded G colour (near-colourless) and VS1 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG833661474 or 833661474. Listed at 9 retailers as of November 1, 2026, with prices from $711 to $3,068, a $2,357 spread on the same certified stone. Rare Carat lists it at $3,068. 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.
