About this 3.09ct natural cushion diamond

This 3.09ct natural cushion sits in the three to five carat band, graded I colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 5222927210. Listed at 8 retailers as of November 4, 2026, with a relatively tight 25% 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.
