About this 1.05ct lab-grown cushion diamond

This 1.05ct lab-grown cushion sits in the classic one-carat band, graded G colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG648417762 or 648417762. Listed at 4 retailers as of October 31, 2026, with prices from $786 to $1,131, a $345 spread on the same certified stone. Kay Jewelers lists it at $1,131. 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.
