About this 4.02ct natural cushion diamond

This 4.02ct natural cushion sits in the three to five 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 GIA 2196763572. Listed at 13 retailers as of November 1, 2026, with prices from £24,049 to £43,336, a £19,286 spread on the same certified stone. MOH London lists it at £43,336. 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.
