According to several sources, Ruby Beach was named because of the ruby-like crystals, possibly garnets, that washed up on the beach.

So beach combing on Ruby Beach had me on the lookout for red jewels but I couldn’t find anything precious and valuable.

But in many ways, just wandering along Ruby Beach, the sea stacks rising out of the salt haze, is valuable enough.
This is a sea stack with hole in it. 
The hole turns this sea stack into a rock with a view.
If you continue down the beach there is a series of shallow caves covered in green algae.
Outside the caves, looking in.
Inside the caves, looking out.
Driftwood embedded with beach pebbles.
The beach is a mix of smoothly rounded pebbles and sand. Here is a family of beach pebbles.
