About this 4.06ct natural cushion diamond

This 4.06ct 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 2231967353. Listed at 8 retailers as of November 4, 2026, with prices from $45,571 to $74,078, a $28,507 spread on the same certified stone. MOH London lists it at $74,078. 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.
