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 VVS2 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG659431356 or 659431356. Listed at 16 retailers as of November 1, 2026, with prices from $235 to $1,640, a $1,405 spread on the same certified stone. Do Amore Diamonds lists it at $1,640. 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.
