What is described as a number of cultured pearl strands bundled together?

The term that describes a number of cultured pearl strands bundled together is known as a hank. In the jewelry industry, a hank typically refers to a collection of pearls that have been strung together. This is often done to facilitate easier handling and sale of the pearls, especially in bulk.

A strand of pearls refers to a single line of pearls that are strung together, which doesn't capture the concept of multiple strands. A pearl necklace is a more finished piece of jewelry, usually made from multiple pearls, but it generally suggests a complete design meant for wearing, rather than just a collection of strands. Similarly, a pearl bracelet implies a specific type of jewelry designed to be worn around the wrist, indicating a lack of multiple strands as a single unit. The term hank, however, accurately encapsulates the idea of numerous strands of cultured pearls grouped together, making it the appropriate choice in this context.
