I have a skin but no scales, a stone but no heart, and though I am often purple, I was once a tiny white flower. If you dry me out, I change my name entirely. What am I?

Designed to hold from dirt to gold, durable in climates hot to cold, filled with fortune or so im told, a pirates dream it may seem

I AM versatile, thanks for noticing! Most know me by my support role, I hold up my responsibility and take it seriously. Sometimes, I even need to hold it back! Occasionally, I don't want to be seen and trust me, you'll never find me, except maybe if I popped out for whatever reason. Sometimes I need to be a part of the show so I'll swap to something more decorative and pretty, definitely catch the light. Don't get the wrong idea, I could be used to pick locks, and can describe a tight turn usually found on steep hills. Be careful on those!

I can speak without a mouth, I capture waves from north to south, i can entertain you from in your house, i can be loud like a whale or quiet like a mouse.
