About this 0.77ct natural cushion diamond

This 0.77ct natural cushion sits in the just-under-one-carat band, graded D colour (colourless) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 6562503019. Listed at 4 retailers as of November 1, 2026, with a relatively tight 15% spread, which is unusual at this carat range and suggests competitive pricing across the listings. 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.
