This 0.78ct lab-grown cushion sits in the just-under-one-carat band, graded E colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG729567243 or 729567243. Listed at 19 retailers as of October 28, 2026, with prices from $263 to $2,670, a $2,407 spread on the same certified stone. Do Amore Diamonds lists it at $2,670. 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.
