About this 3.02ct natural cushion diamond

This 3.02ct 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 GIA 5242023799. Listed at 12 retailers as of November 4, 2026, with prices from £11,663 to £20,119, a £8,456 spread on the same certified stone. MOH London lists it at £20,119. 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.
