About this 1.55ct lab-grown cushion diamond

This 1.55ct lab-grown cushion sits in the one-and-a-half to two carat band, graded E colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG683565140 or 683565140. Listed at 15 retailers as of October 30, 2026, with prices from $1,140 to $4,671, a $3,531 spread on the same certified stone. With Clarity lists it at $4,671. 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.
