About this 3.16ct lab-grown cushion diamond

This 3.16ct 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 LG603358564 or 603358564. Listed at 14 retailers as of November 1, 2026, with prices from $745 to $5,907, a $5,163 spread on the same certified stone. Do Amore Diamonds lists it at $5,907. 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.
