This 4.64ct lab-grown cushion sits in the three to five carat band, graded E colour (colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG735581812 or 735581812. Listed at 3 retailers as of October 30, 2026, with prices from $10,255 to $12,296, a $2,040 spread on the same certified stone. Kay Jewelers lists it at $12,296. 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.
