About this 0.78ct lab-grown cushion diamond

This 0.78ct lab-grown cushion sits in the just-under-one-carat band, graded E colour (colourless) and VS2 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG659416423 or 659416423. Listed at 4 retailers as of October 29, 2026, with prices from €408 to €546, a €138 spread on the same certified stone. Kay Jewelers lists it at €546. 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.
