About this 3.5ct natural cushion diamond

This 3.5ct natural cushion sits in the three to five carat band, graded F colour (colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 5563607154. Listed at 15 retailers as of November 6, 2026, with prices from $66,766 to $120,908, a $54,142 spread on the same certified stone. MOH London lists it at $120,908. 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.
