Singularity

A gravitational singularity, spacetime singularity or simply singularity is a condition in which gravity is so intense that spacetime itself breaks down catastrophically.

Or....

1. the condition or quality of being singular.

2. a unique, distinct, or peculiar feature or thing.

This is a collection of the later two definitions. Unique and amazing items I have picked up around India and the rest of the world.

Could also be something that the ladies made, one-of-a-kind.

One-of-a-kind, unique, singularities - once they are gone, they are gone.
