Is Gold Plated Jewellery "Waterproof"?
For traditional gold plating, the short answer is no. Standard gold electroplating is not considered waterproof. While the gold layer itself doesn't readily react with pure water, the overall construction (a thin layer over a potentially reactive base metal) makes it highly susceptible to damage from moisture, chemicals, and salts found in various water sources. Plated items simply don't have the inherent resilience of solid materials.
However, it's important to note that advancements in plating technology offer exceptions. For instance, here at Kaleya Studio, we utilise an advanced 18k gold Physical Vapor Deposition (PVD) coating, often applied over a durable 316L stainless steel base. This PVD process creates a much stronger, denser, and more resilient bond compared to traditional electroplating.
Consequently, jewellery made with this specific combination (PVD on stainless steel) is designed to be effectively waterproof, capable of handling daily activities like swimming, showering, and sweating with significantly higher resistance to tarnish and wear, making it ideal for daily life.
Truly water-resistant or fully waterproof materials (distinct from coatings) typically include high-karat solid gold, platinum, surgical-grade stainless steel (as a base or on its own), and titanium. These materials have inherent properties that resist water damage far better than traditionally plated base metals.
Why Water Exposure is Risky for Gold Plating
It's not usually the thin gold layer itself that reacts dramatically with plain water, but rather how water interacts with the entire piece:
It's All About the Base (Metal)
The primary culprit is the base metal beneath the gold. Brass, copper, nickel, and other alloys are much more reactive than gold. Water acts as a catalyst, allowing these metals to interact with air, salts, or chemicals. Even microscopic pores in the plating or areas where wear has begun can allow moisture to reach this reactive base layer.
Triggering Tarnish & Corrosion
When moisture reaches the base metal, it can cause:
- Oxidation: Reacting with oxygen in the air, leading to tarnish (darkening).
- Chemical Reactions: Interacting with chlorine, sulphur (in some soaps), salts, and acids, causing corrosion or discolouration. This tarnish often looks like black, green, or brown spots that can become visible through thin plating or creep out from edges.
Accelerating Plating Wear
While pure water isn't abrasive, the things in water can be. Chlorine is corrosive, salts can be abrasive, and minerals in hard UK tap water can leave deposits. Furthermore, the process of repeatedly wetting and then rubbing jewellery dry increases friction, physically wearing down the delicate gold layer over time.
The Problem with Trapped Moisture
Intricate designs, chain links, clasps, and stone settings can easily trap water. This hidden moisture means prolonged contact between water, air, and the base metal, creating an ideal environment for tarnishing and corrosion long after you thought the piece was dry.
Different Types of Water, Different Levels of Risk
Not all water is created equal when it comes to gold plating:
- Plain Tap Water: Quick, accidental splashes are the least damaging, provided you dry the piece immediately and thoroughly. However, repeated exposure is still ill-advised, and hard water minerals can build up.
- Showering/Bathing: Definitely avoid. This involves prolonged exposure not just to water but also to soaps, shampoos, conditioners, and body washes containing various chemicals and surfactants that can dull, corrode, or tarnish the piece rapidly.
- Swimming Pools (Chlorine): Extremely damaging. Chlorine is a potent chemical that actively attacks many base metals and can even degrade the gold plating itself. It's one of the fastest ways to ruin plated jewellery.
- The Sea & Salt Water: Very damaging. Salt is highly corrosive to base metals and can also be abrasive, accelerating wear on the plating.
- Sweat (Perspiration): Contains salts and can be acidic. Exercising or wearing plated jewellery in hot weather where you sweat significantly can contribute to tarnishing and wear over time. Always remove pieces before a workout!
What Does Water Damage Look Like on Gold Plating?
If your gold-plated piece has suffered water damage, you might observe:
- Dullness or Fading: The bright, reflective gold shine diminishes.
- Tarnishing: Noticeable dark spots or patches – often black, greenish (especially with copper bases), or brownish.
- Visible Base Metal: The plating wears thin or flakes, revealing the different coloured metal underneath, particularly on high-friction areas like ring bands or clasp edges.
- Skin Discolouration: Occasionally, a green or black mark may appear on your skin where the jewellery sat. This is a harmless reaction to the base metal (often copper or nickel) interacting with your skin's chemistry, amplified by moisture.
Oops! What to Do if Your Gold Plated Jewellery Does Get Wet
Accidents happen! If your piece gets wet:
- Act Fast: Don't let water sit on it.
- Rinse (If Necessary): If it was exposed to chlorine, salt water, or heavy soaps, give it a very quick rinse under cool, plain tap water to remove harmful residues.
- Dry Thoroughly & Immediately: This is CRITICAL. Use a soft, absorbent, lint-free cloth (microfibre cloths are excellent). Gently pat and wipe every surface dry. Pay close attention to details like chain links, clasps, and around stone settings. Do not rub aggressively.
- Air Dry Further (Optional but Recommended): Leave the piece on a dry towel or cloth for an hour or so to ensure any hidden moisture evaporates before storing it.
Prevention is Key: Keeping Your Plated Jewellery Dry & Beautiful
The best strategy is always prevention:
- Make it a habit: Remove gold-plated jewellery before showering, bathing, swimming, washing dishes, doing household cleaning, or applying lotions, perfumes, hairspray, or hand sanitisers.
- Last On, First Off: Put jewellery on after getting dressed and applying toiletries, and take it off first before undressing or washing up.
- Store Smart: Keep pieces in a dry environment (your bathroom is often too humid). Store them individually in soft pouches or a lined jewellery box to prevent scratching and minimise air exposure.
Is Gold Plated Jewellery "Waterproof"?
In short, no. Gold plated jewellery is not considered waterproof. While the gold layer itself doesn't readily react with pure water, the overall construction (thin layer over a reactive base metal) makes it highly susceptible to damage from moisture, chemicals, and salts found in various water sources.
Truly water-resistant or waterproof jewellery materials typically include high-karat solid gold, platinum, surgical-grade stainless steel, or titanium. Plated items simply don't have the same resilience.
Conclusion: Protect Your Plated Treasures from Water
For most traditionally gold-plated jewellery, getting it wet is a gamble that often doesn't pay off. Water, especially when combined with chemicals like chlorine or salt, primarily attacks the base metal beneath the thin gold layer, leading to unsightly tarnish, corrosion, and accelerated wear.
While a quick splash of plain water, dried immediately, might not cause instant ruin for standard plating, consistent exposure or contact with harsh substances will undoubtedly shorten its life and diminish its beauty. Unless you have jewellery specifically designed with advanced water-resistant technology like PVD coating on stainless steel, the golden rule remains: Keep your gold-plated jewellery dry. By taking these simple preventative steps, you can ensure your affordable and stylish accessories stay looking their best for much longer.
