About this 1.05ct lab-grown cushion diamond

This 1.05ct lab-grown cushion sits in the classic one-carat band, graded D colour (colourless) and VVS1 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG794629446 or 794629446. Listed at 18 retailers as of October 27, 2026, with prices from $491 to $2,676, a $2,185 spread on the same certified stone. Queensmith lists it at $2,676. 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.
