About this 1.18ct lab-grown cushion diamond

This 1.18ct 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 LG800663086 or 800663086. Listed at 15 retailers as of October 30, 2026, with prices from $481 to $2,518, a $2,038 spread on the same certified stone. Michael Trio lists it at $2,518. 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.
