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 SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 2564628299. Listed at 3 retailers as of November 6, 2026, with prices from £22,869 to £29,134, a £6,265 spread on the same certified stone. Yorxs lists it at £29,134. 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.
