This 1.83ct lab-grown cushion sits in the one-and-a-half to two carat band, graded D colour (colourless) and FL clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG840634991 or 840634991. Listed at 17 retailers as of October 31, 2026, with prices from $915 to $5,548, a $4,633 spread on the same certified stone. Brilliant Earth lists it at $5,548. 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.
