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 5186144501. Listed at 13 retailers as of November 1, 2026, with prices from $60,701 to $109,441, a $48,740 spread on the same certified stone. MOH London lists it at $109,441. 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.
