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 LG800684852 or 800684852. Listed at 10 retailers as of October 31, 2026, with prices from $1,248 to $7,588, a $6,339 spread on the same certified stone. Do Amore Diamonds lists it at $7,588. 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.
