About this 1.04ct natural cushion diamond

This 1.04ct natural cushion sits in the classic one-carat band, graded K colour (faint-tinted) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by HRD 16017650006. Listed at 3 retailers as of November 5, 2026, with a relatively tight 16% 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.
