About this 1.7ct natural cushion diamond

This 1.7ct natural cushion sits in the one-and-a-half to two carat band, graded K colour (faint-tinted) and VS1 clarity (very-slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 2231982478. Listed at 15 retailers as of November 2, 2026, with prices from $4,340 to $9,647, a $5,307 spread on the same certified stone. MOH London lists it at $9,647. 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.
