I made jewelry from a Chladni plate! 

Silver and gold Chladni plate turned in to jewelry!
The gold patterns are made thru a process called cymatic, gold dust is sprinkled on to a silver plate and and sound (high frequency tones) are sendt thru the metall and patterns develope, I then heat the it so much that the silver and gold fuses.
The metal is then shaped in to two half spheres using goldsmith techniques.
The two stones you see is rutile quartz and is a perfect fit for this piece!
