This 3.11ct lab-grown cushion sits in the three to five carat band, graded H colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG447069256 or 447069256. Listed at 8 retailers as of November 6, 2026, with prices from $1,243 to $6,273, a $5,030 spread on the same certified stone. Do Amore Diamonds lists it at $6,273. 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.
