This 6.15ct lab-grown cushion sits in the over five carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG593371964 or 593371964. Listed at 12 retailers as of October 30, 2026, with prices from $7,677 to $46,670, a $38,993 spread on the same certified stone. Do Amore Diamonds lists it at $46,670. 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.
