About this 0.78ct lab-grown cushion diamond

This 0.78ct lab-grown cushion sits in the just-under-one-carat band, graded D colour (colourless) and VVS1 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG826603897 or 826603897. Listed at 4 retailers as of October 31, 2026, with prices from $912 to $1,215, a $303 spread on the same certified stone. Kay Jewelers lists it at $1,215. 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.
