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 LG508155768 or 508155768. Listed at 8 retailers as of November 5, 2026, with prices from $543 to $2,401, a $1,858 spread on the same certified stone. MOH London lists it at $2,401. 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.
