About this 3ct natural cushion diamond

This 3ct natural cushion sits in the three to five carat band, graded D colour (colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 2566794172. Listed at 12 retailers as of November 4, 2026, with prices from £21,347 to £39,821, a £18,474 spread on the same certified stone. MOH London lists it at £39,821. 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.
