About this 1.58ct lab-grown cushion diamond

This 1.58ct 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 standard cut grade and certified by IGI LG782690947 or 782690947. Listed at 11 retailers as of October 31, 2026, with prices from $1,016 to $3,953, a $2,938 spread on the same certified stone. Brilliant Earth lists it at $3,953. 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.
