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 VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG842631112 or 842631112. Listed at 7 retailers as of October 31, 2026, with prices from $421 to $2,160, a $1,740 spread on the same certified stone. Taylor and Hart lists it at $2,160. 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.
