About this 3.48ct lab-grown cushion diamond

This 3.48ct lab-grown cushion sits in the three to five carat band, graded E colour (colourless) and VS2 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG820605478 or 820605478. Listed at 16 retailers as of October 29, 2026, with prices from $1,211 to $10,790, a $9,579 spread on the same certified stone. Brilliant Earth lists it at $10,790. 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.
