This 1.01ct lab-grown cushion sits in the classic one-carat band, graded E colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG816607704 or 816607704. Listed at 8 retailers as of October 28, 2026, with prices from $447 to $1,749, a $1,302 spread on the same certified stone. Reve Diamonds lists it at $1,749. 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.
