This 2.66ct lab-grown cushion sits in the two to three carat band, graded G colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG741528327 or 741528327. Listed at 6 retailers as of November 2, 2026, with prices from $1,740 to $5,187, a $3,447 spread on the same certified stone. Taylor and Hart lists it at $5,187. 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.
