This 4.22ct lab-grown cushion sits in the three to five carat band, graded D colour (colourless) and FL clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG784642595 or 784642595. Listed at 10 retailers as of October 31, 2026, with prices from $5,813 to $36,273, a $30,461 spread on the same certified stone. Do Amore Diamonds lists it at $36,273. 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.
