This 1.03ct lab-grown cushion sits in the classic one-carat band, graded F colour (colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG818658582 or 818658582. Listed at 15 retailers as of November 3, 2026, with prices from $274 to $1,572, a $1,298 spread on the same certified stone. Reve Diamonds lists it at $1,572. 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.
