About this 1.2ct lab-grown cushion diamond

This 1.2ct lab-grown cushion sits in the classic one-carat band, graded F colour (colourless) and FL clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG790644838 or 790644838. Listed at 13 retailers as of November 6, 2026, with prices from $1,499 to $5,482, a $3,983 spread on the same certified stone. Taylor and Hart lists it at $5,482. 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.
