About this 3.51ct lab-grown cushion diamond

This 3.51ct lab-grown cushion sits in the three to five carat band, graded G colour (near-colourless) and VS2 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG841661523 or 841661523. Listed at 14 retailers as of October 31, 2026, with prices from $1,136 to $5,625, a $4,489 spread on the same certified stone. Brilliant Earth lists it at $5,625. 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.
