This 3.18ct lab-grown cushion sits in the three to five carat band, graded H colour (near-colourless) and VVS2 clarity (very-very-slightly-included), with a standard cut grade and certified by IGI LG6442700314 or 6442700314. Listed at 2 retailers as of November 1, 2026, with prices from $1,810 to $8,960, a $7,150 spread on the same certified stone. Do Amore Diamonds lists it at $8,960. 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.
