About this 3.58ct lab-grown cushion diamond

This 3.58ct lab-grown cushion sits in the three to five carat band, graded E colour (colourless) and IF clarity (flawless or internally-flawless), with a standard cut grade and certified by IGI LG737584113 or 737584113. Listed at 20 retailers as of October 30, 2026, with prices from $5,119 to $16,938, a $11,819 spread on the same certified stone. Taylor and Hart lists it at $16,938. 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.
