About this 3.56ct lab-grown cushion diamond

This 3.56ct lab-grown cushion sits in the three to five carat band, graded F colour (colourless) and VVS1 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG770679689 or 770679689. Listed at 22 retailers as of November 1, 2026, with prices from $1,490 to $8,274, a $6,785 spread on the same certified stone. Brilliant Earth lists it at $8,274. 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.
