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 14 retailers as of November 6, 2026, with prices from $301 to $1,577, a $1,275 spread on the same certified stone. Reve Diamonds lists it at $1,577. 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.
