About this 1.06ct lab-grown cushion diamond

This 1.06ct lab-grown cushion sits in the classic one-carat band, graded E colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG800610824 or 800610824. Listed at 12 retailers as of November 6, 2026, with prices from $379 to $1,963, a $1,585 spread on the same certified stone. Reve Diamonds lists it at $1,963. 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.
