This 1.54ct lab-grown cushion sits in the one-and-a-half to two carat band, graded G colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG615387583 or 615387583. Listed at 12 retailers as of November 4, 2026, with prices from $334 to $2,851, a $2,517 spread on the same certified stone. Do Amore Diamonds lists it at $2,851. 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.
