About this 3ct natural cushion diamond

This 3ct 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 5543753980. Listed at 11 retailers as of November 4, 2026, with prices from $21,381 to $38,926, a $17,545 spread on the same certified stone. MOH London lists it at $38,926. 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.
