About this 0.86ct lab-grown cushion diamond

This 0.86ct lab-grown cushion sits in the just-under-one-carat band, graded E colour (colourless) and VVS1 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG510187215 or 510187215. Listed at 11 retailers as of October 28, 2026, with prices from $330 to $1,793, a $1,463 spread on the same certified stone. Taylor and Hart lists it at $1,793. 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.
