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 4, 2026, with prices from £34,274 to £62,234, a £27,960 spread on the same certified stone. MOH London lists it at £62,234. 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.
