About this 1.29ct natural cushion diamond

This 1.29ct natural cushion sits in the one-and-a-quarter to one-and-a-half 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 5553493585. Listed at 4 retailers as of November 4, 2026, with prices from $2,174 to $4,115, a $1,941 spread on the same certified stone. MOH London lists it at $4,115. 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.
