How is our jewelry waterproof?

The Stack was founded with the intention to provide affordable long lasting jewelry to the minimalist and active person. Made with a strong base of stainless steel or titanium steel and PVD coated in either 14 or 18k gold- our pieces are made and tested to last. You can wear them to work out, swim, shower and sleep.

Stainless steel does not react with other metals, thus making it less resistant to tarnishing than other metals like copper or brass.
