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 28, 2026, with prices from $144 to $1,346, a $1,202 spread on the same certified stone. MOH London lists it at $1,346. 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.
