About this 1.02ct lab-grown cushion diamond

This 1.02ct lab-grown cushion sits in the classic one-carat band, graded E colour (colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG841637101 or 841637101. Listed at 17 retailers as of October 28, 2026, with prices from $326 to $1,975, a $1,649 spread on the same certified stone. Reve Diamonds lists it at $1,975. 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.
