This 4.3ct 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 LG784646949 or 784646949. Listed at 10 retailers as of October 30, 2026, with prices from $5,831 to $36,928, a $31,097 spread on the same certified stone. Do Amore Diamonds lists it at $36,928. 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.
