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 29, 2026, with prices from $2,885 to $9,546, a $6,661 spread on the same certified stone. Taylor and Hart lists it at $9,546. 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.
