About this 1.81ct natural cushion diamond

This 1.81ct natural cushion sits in the one-and-a-half to two 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 7451255837. Listed at 14 retailers as of November 4, 2026, with prices from $2,642 to $5,742, a $3,100 spread on the same certified stone. MOH London lists it at $5,742. 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.
