About this 1.24ct natural cushion diamond

This 1.24ct natural cushion sits in the classic one-carat band, graded D colour (colourless) and SI2 clarity (slightly-included) and certified by GIA 2125067351. Listed at 2 retailers as of October 31, 2026, with a relatively tight 6% 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.
