What kind of rock is this?

[LDennis24]

Found this rock on the beach and decided I had to have it. Almost gave me a hernia picking it up! Awkward shape and weighed over 100 lbs.  It's really teal colored and almost translucent like jade would be.

What beach?

[Knocker of rocks]

I hate identifying rocks on the web, there is so much you can’t see. Salt water also turns the surficial color orange or green.

By the beach, I assume the Washington coast?  Rocks there are surficial greywacke seds and lavas of the crescent. Deeper portions of the crescent are also exposed in some places that Roland tabor refered to as ophiolite like.   

All that said, it looks like a green fine grained andesitic clast in a coarse matrix like a sand. Submarine landslides can also jumble all those ingredients together.
