This 4.25ct 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 LG784642755 or 784642755. Listed at 11 retailers as of October 31, 2026, with prices from $5,851 to $36,515, a $30,664 spread on the same certified stone. Do Amore Diamonds lists it at $36,515. 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.
