About this 3.01ct natural cushion diamond

This 3.01ct natural cushion sits in the three to five 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 HRD 170001831859. Listed at 3 retailers as of November 4, 2026, with prices from £11,689 to £17,319, a £5,630 spread on the same certified stone. MOH London lists it at £17,319. 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.
