This 1.01ct lab-grown cushion sits in the classic one-carat band, graded D colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG847632688 or 847632688. Listed at 12 retailers as of November 1, 2026, with prices from $368 to $1,925, a $1,557 spread on the same certified stone. Reve Diamonds lists it at $1,925. 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.
