About this 1.58ct natural cushion diamond

This 1.58ct natural cushion sits in the one-and-a-half to two carat band, graded J colour (near-colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 6555097162. Listed at 19 retailers as of November 1, 2026, with prices from $4,610 to $9,853, a $5,243 spread on the same certified stone. MOH London lists it at $9,853. 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.
