About this 0.91ct lab-grown cushion diamond

This 0.91ct lab-grown cushion sits in the just-under-one-carat band, graded D colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG576348287 or 576348287. Listed at 4 retailers as of October 31, 2026, with prices from $708 to $982, a $275 spread on the same certified stone. Kay Jewelers lists it at $982. 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.
