Trends come and go. Some do bring value, and sometimes it's got more to do with marketing. One that’s splashing into focus right now is waterproof jewellery.
According to various brands, there is a new jewellery option that is completely waterproof and tarnish-free. However, all jewellery is vulnerable to water.
Solid gold (9k to 18k jewellery) stands up to water better than plated jewellery, which is logical since plated or vermeil jewellery consists of a micro-thin film of gold over a base of other metals.
The reality is that even solid gold will lose its shine, pit, or tarnish with repeated water exposure. Water itself is tough—just look at the erosion it is capable of creating in nature. Water can cut deep into the earth and create lasting environmental effects over time. No metal is invincible against water over time. Water types and pH levels can cause even the toughest metals to be damaged, not to mention the added chemicals in water, like chlorine.
To extend the life of plated pieces, Physical Vapor Deposition (PVD) is a modern coating process that is ‘flooding’ the market right now. It involves a thin film of one atom or molecule deposited onto the metal, which reconditions the surface of a jewellery piece.
Essentially, it is a surface modification rather than an added layer of material. It is considered a stronger alternative to standard silver or gold-plated jewelry, but it is still just a coating. It is a nice addition to keep your jewellery shining for longer, but it is not going to last despite how much the marketers put their spin on it.
For jewellery to really last, it requires considered wear, gentle cleaning, and sensible storage.
Metals to Protect
Silver really dislikes water and soap. Over time, it will turn black and can potentially be irreversibly damaged by water exposure.
Gold in yellow or rose fare better than most but constant exposure will cause wear and damage over time. Gold contains traces of copper and zinc, so prolonged exposure to chemicals will certainly dull its shine.
Gold in white has plated finish in rhodium, a metal more expensive than gold itself but that coating will wear off and need re-plating. Water will speed that process along.
Gold-plated or vermeil pieces will also lose shine and worse still, it will likely see the surface chip off, exposing the metal underneath.
Silver and solid gold are strong and durable enough to withstand reasonable daily wear. They can last forever with the right care.
