This 0.78ct lab-grown cushion sits in the just-under-one-carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG756513797 or 756513797. Listed at 13 retailers as of November 4, 2026, with prices from $525 to $3,436, a $2,911 spread on the same certified stone. Do Amore Diamonds lists it at $3,436. 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.
