About this 1.04ct lab-grown cushion diamond

This 1.04ct lab-grown cushion sits in the classic one-carat band, graded E colour (colourless) and VVS1 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG816607817 or 816607817. Listed at 16 retailers as of October 27, 2026, with prices from $342 to $1,829, a $1,487 spread on the same certified stone. Queensmith lists it at $1,829. 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.
