About this 3.51ct natural cushion diamond

This 3.51ct natural cushion sits in the three to five carat band, graded H colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 3555137190. Listed at 11 retailers as of November 4, 2026, with prices from $59,226 to $109,794, a $50,568 spread on the same certified stone. MOH London lists it at $109,794. 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.
