About this 1.71ct natural cushion diamond

This 1.71ct natural cushion sits in the one-and-a-half to two carat band, graded I colour (near-colourless) and SI2 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 6405453710. Listed at 19 retailers as of October 31, 2026, with prices from $8,485 to $15,917, a $7,433 spread on the same certified stone. MOH London lists it at $15,917. 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.
