Different Types of Gold Jewelry Explained (10k, 14k, 18k, 24k)

Let’s be honest—choosing gold jewelry is almost as tricky as picking your Starbucks order. Is 14k gold better than 18k? What even is PVD gold? And wait—is gold-filled jewelry waterproof?

Don’t worry. We’ve got you. Whether you're shopping for waterproof earrings that can handle a dive into the ocean, or work friendly jewelry that won’t quit on you by 2 p.m., this guide breaks down every gold type, so you know exactly what sparkles best for your style—and your skin.

24k Gold: Pure, Pricey, and (Kind of) Problematic

24k gold is 100% pure gold—a luxurious, buttery metal straight from treasure chests and royal crowns. Sounds perfect, right?

Well, not so fast.

Pure gold is soft. Like, bend-it-with-your-fingernail soft. That means it's not ideal for everyday wear. It scratches, warps, and won’t hold up if you’re living your best beach safe jewelry life.

Best for: Collectors, heirlooms, or pieces that won’t be worn often.

Avoid if: You want sweat-proof jewelry, ocean proof jewelry, or anything remotely waterproof.

18k Gold: Luxe Meets Practical

18k gold contains 75% pure gold, with 25% alloyed metals to give it strength. It has that rich golden tone everyone dreams of, without being overly soft.

It’s a great middle ground if you want that high-end look in something a little more durable. But heads-up: it's still on the softer side.

Best for: Special occasion pieces, or elevated wedding guest jewelry vibes.

Not ideal for: Everyday jewelry or active lifestyles (hello, gym girlies 👋).

14k Gold: The Real MVP

14k gold is the go-to for tarnish free jewelry lovers. It’s 58.3% pure gold, and the rest is a perfect blend of metals that make it stronger, more durable, and much more affordable.

Bonus? It’s the most common choice for waterproof jewelry, jewelry that doesn’t tarnish, and jewelry that is safe for sensitive skin.

Best for: Literally everyone. From beach brides to boardroom babes.

Also great for: Waterproof rings, hypoallergenic jewelry, and jewelry that doesn't make your skin turn green.

10k Gold: Tough Love

Containing just 41.7% gold, 10k is durable, budget-friendly, and definitely tough enough for everyday wear.

But here's the thing: It’s not as yellow or rich-looking as higher karats. Some people also find it slightly more reactive on sensitive skin (depending on the alloy mix).

Best for: Teen jewelry, stacking pieces, or items that take a beating.

Still counts as: Tarnish free, sweat-proof, and work friendly jewelry.

Is Gold-Filled Jewelry Waterproof?

Gold-filled jewelry sounds fancy—and it kinda is. It’s made by mechanically bonding a thick layer of real gold over a base metal (usually brass).

So, is gold-filled jewelry waterproof? Mostly yes! It holds up beautifully against sweat and splashes, but avoid hot tubs and harsh chemicals to make it last.

It’s a solid pick for: Waterproof anti tarnish jewelry, beach safe jewelry, and jewelry that doesn’t make your skin turn green.

What Is PVD Gold? (And Why It’s a Game Changer)

PVD stands for Physical Vapor Deposition, which is a high-tech way to coat stainless steel with real gold in a super durable finish.

Unlike regular plating, PVD gold doesn’t flake or rub off easily. It’s waterproof, hypoallergenic, and tarnish-resistant—a favorite for new jewelry styles that need to survive your wild weekends and 9-to-5 hustle.

Perfect for: Gold plated stainless steel lovers who want long-lasting shine without babying their pieces.

Is Stainless Steel Waterproof?

Yes, and hell yes. Stainless steel is the MVP of waterproof jewelry. It’s rust-proof, corrosion-resistant, and tough enough for the pool, gym, and yes—even the ocean.

When combined with PVD gold plating, you’ve got an unstoppable piece of waterproof anti tarnish jewelry that looks luxe and doesn't tarnish.

Also: It’s naturally hypoallergenic, so it’s perfect for sensitive skin jewelry.

Does Gold Stainless Steel Tarnish?

Not really. Especially if it’s PVD gold plated. It stays shiny and golden for a long time—even with daily wear.

Pro tip: If you want your jewelry to keep looking fresh, rinse it after saltwater dips and avoid soaking it in lotions or perfumes. (But you already knew that, right?)

So... What’s the Best Gold for Waterproof Jewelry?

If you’re here for ocean proof jewelry, beach safe jewelry, and waterproof earrings that won’t flinch at a cannonball, go for:

• 14k gold (for real gold lovers)

• Gold-filled (for a budget-friendly waterproof win)

• PVD gold plated stainless steel (for trendsetters who want long wear and zero drama)

Final Sparkle: Match Your Gold to Your Glow-Up

Choosing gold jewelry isn’t just about looks—it’s about lifestyle. From everyday jewelry that holds up on a hike, to wedding-ready waterproof rings, there’s a golden match for everyone.

With the rise of new jewelry trends focusing on function and fashion, there's never been a better time to build a collection that shines through sweat, waves, and workdays.

So go ahead—get golden.✨
