About this 3.51ct natural cushion diamond

This 3.51ct natural cushion sits in the three to five carat band, graded F colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 2504163221. Listed at 13 retailers as of November 4, 2026, with prices from $67,788 to $111,582, a $43,795 spread on the same certified stone. MOH London lists it at $111,582. 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.
