This 0.86ct lab-grown cushion sits in the just-under-one-carat band, graded E colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG689535249 or 689535249. Listed at 14 retailers as of October 29, 2026, with prices from $256 to $2,397, a $2,141 spread on the same certified stone. MOH London lists it at $2,397. 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.
