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 LG807613909 or 807613909. Listed at 20 retailers as of November 3, 2026, with prices from $449 to $3,835, a $3,386 spread on the same certified stone. Do Amore Diamonds lists it at $3,835. 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.
