Before we get things started, let’s clear up a very important and very dangerous misconception! Lots of products nowadays, especially technology, come with descriptions or warnings that tell you whether an item is waterproof or water resistant. Considering its similarities, these two things tend to be used interchangeably, when in fact they are very different and could very much ruin the very important and possibly even very expensive wedding jewelry you just purchased.
Water resistance means that an item can only withstand the penetration of water up to certain amounts, but not entirely. Water resistant items are usually safe for when you have to wash your hands or take a shower, but may get water damage when having a swim at the pool for a prolonged period of time.
Waterproof means that an item is completely impervious to water and can resist it entirely, no matter how much time it is spent in water. Waterproof items are safe to use at pools and beaches without the threat of rusting and corrosion. However, do take note that while some materials are waterproof, they may still be vulnerable to other harsh chemicals that may potentially be mixed with water, like chlorine.
