Antique pendant with blister pearl & old cut diamonds, around 1900

It is impossible to imagine the world of jewellery without the pearl. However, before the Japanese entrepreneur Mikimoto invented pearl cultivation and thus revolutionized the pearl market in the 1920s, real pearls were so rare and so precious that, depending on their size, they were priced like diamonds. For jewellery other than pearl necklaces, for which full round pearls were needed, not only round pearls were used, but also the so-called blister pearls. Such pearls are formed when predators of the mollusk try to penetrate the mollusk shell in order to reach the mollusk flesh. The defensible mussel seals the pierced shell with nacre, which also creates pearls, which, however, are firmly attached to the mussel shell. These resulting blister beads with unique shapes are regularly found in antique jewelry. A very large blister pearl is at the center of the present pendant and was apparently also the starting point for the design. A frame of 2.83 ct individually cut diamonds frames the teardrop-shaped blister pearl, the body of which is slightly baroque in shape and has a melting luster. The front of the pendant is crafted in silver, typical of the period, while the back is gold. Much attention has been paid even to the details: For example, the setting of the pearl on the back is ornamentally worked and openworked. In its design, workmanship and choice of materials, the pendant corresponds to the style of the Belle Époque, as it was represented in the ballrooms of all the major Western metropolises around 1900. We have added a matching chain to the antique pendant and had an external appraisal made.
