About this 1ct natural cushion diamond
This 1ct natural cushion sits in the classic one-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 6381887861. Listed at 22 retailers as of November 4, 2026, with prices from $2,278 to $4,799, a $2,521 spread on the same certified stone. MOH London lists it at $4,799. 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.
