This 1.5ct lab-grown cushion sits in the one-and-a-half to two carat band, graded G colour (near-colourless) and SI1 clarity (slightly-included), with a standard cut grade and certified by IGI LG524214586 or 524214586. Listed at 11 retailers as of November 6, 2026, with prices from $423 to $3,277, a $2,854 spread on the same certified stone. Do Amore Diamonds lists it at $3,277. 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.
