About this 3.33ct lab-grown cushion diamond

This 3.33ct 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 LG651420724 or 651420724. Listed at 4 retailers as of November 2, 2026, with prices from $1,590 to $3,190, a $1,600 spread on the same certified stone. Kay Jewelers lists it at $3,190. 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.
