About this 1.06ct natural cushion diamond

This 1.06ct natural cushion sits in the classic one-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 1559493546. Listed at 4 retailers as of November 4, 2026, with prices from $1,759 to $3,485, a $1,726 spread on the same certified stone. MOH London lists it at $3,485. 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.
