About this 3.11ct lab-grown cushion diamond

This 3.11ct lab-grown cushion sits in the three to five carat band, graded I colour (near-colourless) and VVS2 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG557237350 or 557237350. Listed at 6 retailers as of November 1, 2026, with prices from $913 to $4,490, a $3,577 spread on the same certified stone. Do Amore Diamonds lists it at $4,490. 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.
