About this 3.15ct lab-grown cushion diamond

This 3.15ct lab-grown cushion sits in the three to five carat band, graded I colour (near-colourless) and VS1 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG544273613 or 544273613. Listed at 11 retailers as of November 2, 2026, with prices from $659 to $5,227, a $4,569 spread on the same certified stone. Do Amore Diamonds lists it at $5,227. 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.
