About this 1.46ct lab-grown cushion diamond

This 1.46ct lab-grown cushion sits in the one-and-a-quarter to one-and-a-half carat band, graded E colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG816615278 or 816615278. Listed at 17 retailers as of October 25, 2026, with prices from $490 to $2,933, a $2,443 spread on the same certified stone. Brilliant Earth lists it at $2,933. 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.
