About this 0.8ct lab-grown cushion diamond

This 0.8ct 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 LG510187213 or 510187213. Listed at 6 retailers as of October 29, 2026, with prices from $417 to $1,861, a $1,444 spread on the same certified stone. MOH London lists it at $1,861. 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.
