About this 1.5ct lab-grown cushion diamond

This 1.5ct 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 LG683565149 or 683565149. Listed at 16 retailers as of October 30, 2026, with prices from $1,126 to $6,142, a $5,016 spread on the same certified stone. With Clarity lists it at $6,142. 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.
