About this 1.66ct lab-grown cushion diamond

This 1.66ct 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 LG737526142 or 737526142. Listed at 3 retailers as of October 30, 2026, with prices from $4,001 to $4,807, a $805 spread on the same certified stone. Kay Jewelers lists it at $4,807. 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.
