About this 1.3ct natural cushion diamond

This 1.3ct natural cushion sits in the one-and-a-quarter to one-and-a-half 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 7551719174. Listed at 8 retailers as of November 4, 2026, with prices from $2,446 to $4,630, a $2,184 spread on the same certified stone. MOH London lists it at $4,630. 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.
