About this 3.12ct natural cushion diamond

This 3.12ct natural cushion sits in the three to five carat band, graded M 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 HRD 200000024423. Listed at 6 retailers as of November 4, 2026, with a relatively tight 18% 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.
