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 H 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 6525495680. Listed at 15 retailers as of November 4, 2026, with prices from $3,886 to $7,392, a $3,506 spread on the same certified stone. MOH London lists it at $7,392. 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.
