Are lotus pearls made of glass?

Lotus pearls are not made of glass; they are actually crafted from a type of natural material, often derived from freshwater mollusks. These pearls are formed when an irritant, such as a piece of sand, gets trapped inside the mollusk, prompting it to secrete layers of nacre around the irritant. The result is a lustrous pearl that can be used in jewelry. Some synthetic variations may exist, but genuine lotus pearls are organic in origin.
