About this 1.05ct lab-grown cushion diamond

This 1.05ct 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 LG816615873 or 816615873. Listed at 13 retailers as of October 25, 2026, with prices from $403 to $2,295, a $1,892 spread on the same certified stone. Brilliant Earth lists it at $2,295. 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.
