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 stated by the retailer rather than the lab and certified by GIA 2534614829. Listed at 15 retailers as of October 30, 2026, with prices from $10,727 to $43,109, a $32,383 spread on the same certified stone. Blue Nile lists it at $43,109. 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.
