About this 1.01ct natural cushion diamond

This 1.01ct 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 6531983557. Listed at 17 retailers as of November 1, 2026, with prices from $1,280 to $3,035, a $1,755 spread on the same certified stone. MOH London lists it at $3,035. 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.
