"Natural Shell Blisters and Blister Pearls: What's the Difference?"
Article by GIA
According to Elisabeth Strack in her amazing book, Pearls, blister pearls are pearls which originally formed as free pearls within the connective tissue of the mantle and which merged later with the shell. At first the pearl will only touch the shell at one point before a first stem-like connection forms.
The inter-growing of pearl and shell takes place in several stages and eventually leads to a complete merger. This means that the pearl will be integrated in the normal growth process of the shell, which increases in thickness during the mollusk's life.
Experienced pearl fishers and pearl dealers are usually aware that certain techniques will enable the original round pearl to be exposed and this can often prove a valuable surprise.
Blisters, sometimes confused with blister pearls, are formed by internal protuberances produced on the inside of the shell.
Blisters form when foreign objects such as larvae, worms, snails, crabs, fishes, tiny pieces of fish bones or tiny stones are flooded into the space between shell and mantle tissue, where they are trapped.
Blisters have irregular shapes and are sometimes hollow on the inside, where they are usually filled with a liquid and /or the rotting or dead remnants of the intruder.
Blisters must be cut out of the inside of the shell if they are to be used in jewelry. The same is true of blister pearls. Both blisters and blister pearls differ from free pearls insofar as the mother-of-pearl layers correspond to those of the shell. In the case of blister pearls, the outer layers have an even, parallel and not concentric arrangement, while the pearl within possesses a concentric structure.
