Sancy Diamant The Sancy Diamond in a white gold setting (1)

Although it is not known exactly when the Sancy Diamond was found, its discovery is dated before 1477, when it was already in the possession of Charles the Bold.

The 55.23-carat yellow-green Sancy diamond stands out due to its special shield-shaped cut . Unlike usual, it does not have a pavilion - the lower part of a gemstone - but is made up of two adjacent crowns. Its facets are arranged symmetrically, which was a novelty at the time.
