About this 1.2ct lab-grown cushion diamond

This 1.2ct lab-grown cushion sits in the classic one-carat band, graded E colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG702592174 or 702592174. Listed at 8 retailers as of October 29, 2026, with prices from $674 to $3,800, a $3,126 spread on the same certified stone. Do Amore Diamonds lists it at $3,800. 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.
