About this 1.18ct lab-grown cushion diamond

This 1.18ct lab-grown cushion sits in the classic one-carat band, graded G colour (near-colourless) and VVS2 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG578350616 or 578350616. Listed at 5 retailers as of November 4, 2026, with prices from $302 to $1,456, a $1,155 spread on the same certified stone. Michael Trio lists it at $1,456. 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.
