About this 3.1ct lab-grown cushion diamond

This 3.1ct lab-grown cushion sits in the three to five carat band, graded E colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG694501775 or 694501775. Listed at 17 retailers as of October 27, 2026, with prices from $1,786 to $6,500, a $4,714 spread on the same certified stone. Taylor and Hart lists it at $6,500. 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.
