About this 4.08ct lab-grown cushion diamond

This 4.08ct 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 LG735516175 or 735516175. Listed at 20 retailers as of October 31, 2026, with prices from $5,683 to $20,514, a $14,831 spread on the same certified stone. Taylor and Hart lists it at $20,514. 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.
