This 4.99ct 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 LG816625863 or 816625863. Listed at 6 retailers as of November 3, 2026, with prices from $9,947 to $20,278, a $10,330 spread on the same certified stone. Brilliant Earth lists it at $20,278. 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.
