There's no official gemstone or stone recognized as the "Bermuda Lucky Stone". The term seems to be a modern, informal reference to pink sand, which is a unique characteristic of many Bermuda beaches.

Here's why it's not considered a traditional gemstone:

* Pink sand is not a single mineral or crystal: It's made up of crushed coral, seashells, and other marine debris.

* There's no formal designation: There's no geological or gemological classification for a "Bermuda Lucky Stone."

While the term is likely used to represent the beauty and luck associated with Bermuda, it doesn't refer to a specific type of stone.
