Do pearls come from oysters?

Do mollusks die when pearls are harvested?
Mollusks do not necessarily die when pearls are harvested, but the process can be harmful to them. If the pearl is removed carefully and the mollusk is healthy, it may survive and even produce more pearls in the future. However, in some cases, the harvesting process can lead to stress or injury that might result in death. Additionally, not all species of mollusks can survive multiple harvesting attempts.
Do sea urchins produce pearls?
Sea urchins do not produce pearls in the same way that oysters do. While oysters create pearls from irritants by secreting layers of nacre, sea urchins have a different defense mechanism. They can form structures called "urchin pearls," which are calcified deposits, but these are not true pearls and are generally not valued like those from mollusks. Instead, sea urchin pearls are often irregular and not sought after in jewelry.
How long does it take natural pearls to form?
Natural pearls can take several years to form inside oysters or mollusks. It typically takes between 5 to 7 years for a pearl to develop to a marketable size. However, some pearls can take even longer, with the most valuable ones forming over 10 years or more.
How is seashells related to pearl?
Seashells are the protective outer layer of mollusks, and pearls are formed within some types of mollusks as a defense mechanism against irritants. Pearls are created when a foreign object, like a grain of sand, enters the mollusk's shell and the mollusk secretes layers of nacre around it, forming a pearl. So, seashells provide the environment for pearls to be produced within certain mollusks.

Is pearls biotic or abiotic?
Pearls are biotic because they are formed by living organisms, specifically mollusks such as oysters and mussels. These creatures produce pearls as a defense mechanism against irritants, layering nacre around the foreign object. Thus, pearls are a natural product of biological processes.
