About this 0.78ct lab-grown cushion diamond

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 30, 2026, with prices from $374 to $3,801, a $3,427 spread on the same certified stone. Do Amore Diamonds lists it at $3,801. 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.
