This 1.86ct lab-grown cushion sits in the one-and-a-half to two carat band, graded F colour (colourless) and VVS1 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG849657529 or 849657529. Listed at 3 retailers as of October 29, 2026, with prices from $661 to $1,245, a $584 spread on the same certified stone. Taylor and Hart lists it at $1,245. 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.
