This 1.05ct 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 LG578347047 or 578347047. Listed at 16 retailers as of October 30, 2026, with prices from $209 to $1,151, a $942 spread on the same certified stone. Reve Diamonds lists it at $1,151. 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.
