About this 1.01ct natural cushion diamond

This 1.01ct natural cushion sits in the classic one-carat band, graded K colour (faint-tinted) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 5242003539. Listed at 12 retailers as of November 5, 2026, with a relatively tight 20% 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.
