About this 1.59ct natural cushion diamond

This 1.59ct natural cushion sits in the one-and-a-half to two carat band, graded J 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 6432021039. Listed at 16 retailers as of October 29, 2026, with prices from $2,865 to $6,270, a $3,405 spread on the same certified stone. MOH London lists it at $6,270. 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.
