About this 1.03ct natural cushion diamond

This 1.03ct natural cushion sits in the classic one-carat band, graded H 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 2534950820. Listed at 18 retailers as of November 4, 2026, with prices from $1,689 to $3,967, a $2,278 spread on the same certified stone. MOH London lists it at $3,967. 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.
