You see a piece of jewelry that says "waterproof" and another that says "water resistant." Are they the same? Can you shower with both? Is one better than the other? They're not the same , and understanding the difference can prevent you from ruining your jewelry.
In this article, we explain exactly what each term means, what level of protection they offer, and how to identify truly water-resistant jewelry. Because you deserve to know exactly what you're buying.
Waterproof vs Water Resistant: The Key Difference
Water Resistant
We have seen hundreds of times how Meaning: The product can withstand some exposure to water , but is not designed to be fully submerged or for prolonged use in water.
In jewelry it means:
- ✅ You can wash your hands without taking it off
- ✅ Resists light splashes
- ✅ It can withstand sweat and ambient humidity
- ⚠️ You should NOT shower with it
- ⚠️ You should NOT swim with her
- ⚠️ You should NOT submerge it completely
Protection duration: Limited. Resistance may decrease over time.
Waterproof
Meaning: The product is designed to withstand complete immersion in water without damage.
In jewelry it means:
- ✅ You can shower with it
- ✅ You can swim (pool and sea)
- ✅ Withstands prolonged immersion
- ✅ Resists intense sweat (gym)
- ✅ It does not rust or deteriorate with water
Protection duration: Permanent (if the material is inherently waterproof, such as 316L steel).
The confusion of marketing
Here's the problem: there's no strict regulation on the use of these terms in jewelry. Some brands overuse "waterproof," while others are more honest with "water resistant."
Misleading terms you'll see:
- "Water friendly": Vague, can mean anything
- "Splash resistant": Only withstands splashes, not immersion
- "Shower safe": This can mean it's shower safe, but not suitable for swimming.
- "Water resistant up to 30m": This is for watches, it rarely applies to jewelry
The reality: In jewelry, what really matters is not the label, but the material .
What materials are truly waterproof?
| Material | Actual classification | Can you take a shower? | Can you swim? | Grades |
|---|---|---|---|---|
| 316L Stainless Steel | Waterproof | ✅ Yes | ✅ Yes | Completely waterproof, it won't rust |
| Titanium | Waterproof | ✅ Yes | ✅ Yes | Extremely durable |
| Platinum | Waterproof | ✅ Yes | ✅ Yes | It does not rust, it is very durable |
| 18k Gold+ | Waterproof | ✅ Yes | ✅ Yes (with caution) | It doesn't rust, but it's soft. |
| 14k gold or less | Water Resistant | ⚠️ Occasional | ❌ Not recommended | It contains alloys that can oxidize |
| 925 Silver | Water Resistant | ⚠️ Occasional | ❌ No | It oxidizes quickly in water. |
| durable gold finish | NOT resistant | ❌ No | ❌ No | The coating wears away with water. |
| Brass/Copper | NOT resistant | ❌ No | ❌ No | It oxidizes and stains the skin |
| Silicone | Waterproof | ✅ Yes | ✅ Yes | Perfect for water sports |
As you can see, 316L stainless steel is one of the few materials that are truly waterproof. That's why we recommend stainless steel jewelry for use in water .
What about stones and pearls?
Even if the metal is waterproof, the stones may not be:
Waterproof stones (safe in water):
- ✅ Diamonds
- ✅ Sapphires
- ✅ Rubies
- ✅ Quartz, amethyst, citrine
- ✅ Cubic zirconia (synthetic)
Non-waterproof stones (avoid water):
- ❌ Pearls (they dry out and crack)
- ❌ Turquoise (absorbs water and fades)
- ❌ Opal (may crack)
- ❌ Emerald (has internal fractures)
- ❌ Coral, amber (organic materials)
Conclusion: A piece of jewelry may have waterproof metal but stones that are not. Always check both components.
Water resistance levels (as in watches)
Watches use a scale of ATM (atmospheres) or meters to indicate water resistance. While this rarely applies to jewelry, it's helpful to understand:
| Classification | Pressure | What does it mean | Can you swim? |
|---|---|---|---|
| Water Resistant | Unspecified | Light splashes only | ❌ No |
| 3 ATM / 30m | 3 bar | Splashes and rain | ❌ No |
| 5 ATM / 50m | 5 bar | Shower and surface swimming | ✅ Yes (superficial) |
| 10 ATM / 100m | 10 bar | Swimming and snorkeling | ✅ Yes |
| 20 ATM / 200m+ | 20+ bar | Professional diving | ✅ Yes (deep) |
NoteThis scale is primarily used for watches. In jewelry, if the material is inherently waterproof (such as 316L stainless steel), it doesn't need an ATM rating because it simply isn't damaged by water.
How to identify truly waterproof jewelry
Don't rely solely on the label. Ask these questions:
1. What material is it made of?
If it's made of 316L stainless steel, titanium, platinum, or high-purity gold, it's waterproof. If it's made of silver, a durable gold finish, or cheap alloys, it's not.
2. Does it have stones? Which ones?
Check that the stones are water-resistant (diamonds, sapphires, rubies). If it has pearls, turquoise, or opals, it is not waterproof.
3. How are the stones set?
If the stones are glued (not prong-set or bezel-set), water may dissolve the glue. It is not waterproof.
4. Does it have parts made of other materials?
Some necklaces have steel chains but brass clasps. Or steel rings with copper details. Those parts are NOT waterproof.
5. Does the brand specify the material?
Reputable brands specify "316L Stainless Steel" or "Grade 5 Titanium." If it only says "metal" or "alloy," it's probably not waterproof.
At PENDELAU , all our waterproof jewelry is made from certified 316L stainless steel. We don't use materials that rust or coatings that wear off.
Myths about waterproof jewelry
Myth 1: "All steel jewelry is waterproof"
FALSE. Only high-quality stainless steel (316L or higher) is truly waterproof. Stainless steel (304 or lower grade) can rust with prolonged exposure to water.
Myth 2: "If it's expensive, it's waterproof"
FALSE. Price does not determine water resistance. A €200 silver jewel is not waterproof, but a €20 steel one can be.
Myth 3: "Water resistant means it can't get wet"
FALSE. Water resistant means it can withstand some water (washing hands, rain), but not prolonged immersion.
Myth 4: "Waterproof means it will never get damaged"
FALSE. Waterproof refers only to water. The jewelry can be damaged by other factors (impacts, harsh chemicals, etc.).
Myth 5: "If it has a warranty, it's waterproof"
FALSE. Read the fine print. Many warranties exclude water damage if the jewelry is not genuinely waterproof.
Care for waterproof jewelry
Even if your jewelry is waterproof, these care tips will keep it perfect:
1. Rinse after swimming in the sea or pool
Salt and chlorine won't damage steel, but they can leave residue. A quick rinse with fresh water will remove it.
2. Dry thoroughly
Although steel doesn't rust, hard water can leave stains when it dries. Dry with a soft cloth.
3. Clean regularly
Water won't damage steel, but sweat, lotions, and sunscreen can build up. Clean it with soap weekly.
4. Check the closures
Even though the metal is waterproof, the locking mechanisms can accumulate sand or dirt. Check them after the beach.

What jewelry is best for water sports?
If you practice swimming, surfing, diving, or any water sport, these are the best options:
Ideal characteristics:
- Waterproof material: 316L steel or titanium
- No loose stones: Avoid jewelry with stones that could fall off.
- Secure closures: Screw or click, no open hooks
- Simple design: No parts that catch on each other
- Firm fit: It shouldn't move around too much during activity.
Specific recommendations:
- Earrings: Small with screw-on closure
- Necklaces: Short chokers that don't move
- Bracelets: Rigid or single chain
- Rings: Plain, without stones
Conclusion: The material matters more than the label
Don't be fooled by marketing terms. The difference between "waterproof" and "water resistant" is important, but what really matters is the material .
If you want jewelry you can wear in the shower, pool, sea, and gym without worry, choose 316L stainless steel . It's genuinely waterproof, requires no special care, and maintains its perfect shine no matter how wet it gets.
