18K Gold: Frequently Asked Questions

Q: What Does 18kt Hge Mean?

“18kt HGE” means 18-karat gold electroplated. It refers to a base metal (usually brass or silver) finished with a thin layer of genuine 18kt gold using a process called High-Grade Electroplate (HGE). This thick plating method is used to give jewelry a gold appearance at a lower price compared to solid gold.

Q: Is 18kt Gold Real?

Yes — 18kt gold is real gold. It’s made of 75% pure gold, blended with 25% alloy metals for strength and durability. The result? Fine jewelry that’s luxe and lasting — without the price of 24kt solid gold.

Q: Will 18kt Gold Tarnish?

Yes — 18kt gold can tarnish over time, but it’s far more resistant than lower-karat options. Pure gold itself doesn’t tarnish, and since 18kt gold is 75% pure, it holds its glow beautifully. That said, the remaining alloy metals (like copper or silver) can react to moisture, chemicals, or humidity, causing slight discoloration if not cared for properly.

To keep your 18kt pieces looking their best? Store them thoughtfully, avoid harsh chemicals, and give them a gentle clean now and then. Treat them right — they’ll shine for years.

Q: Can 18k Gold Rust?

No — 18kt gold doesn’t rust. Rust happens when iron reacts with water and air, and since 18kt gold contains no iron, you’re in the clear. That said, because it’s 75% pure gold and 25% alloy metals (like copper or silver), you might notice a bit of tarnish over time — but that’s not rust, and it’s nothing a quick polish can’t fix.

Q: Can You Wear 18kt Gold in the Shower?

You can wear 18kt gold jewelry in the shower — but we don’t recommend it. While 18kt gold is durable, repeated exposure to water, soaps, and shampoos can dull its shine over time. An occasional rinse won’t ruin it, but if you want to keep that rich glow, it’s best to take your pieces off before you lather up.

Q: Is 18kt Gold Hypoallergenic?

Yes — 18kt gold is generally considered hypoallergenic. With 75% pure gold content, it’s far less likely to irritate skin than lower-karat options that contain more reactive metals (like nickel). That said, no metal is 100% allergy-proof — but for most people, 18kt gold is a safe and skin-friendly choice.

Q: Does 18kt Gold Turn Green?

No — 18kt gold typically won’t turn your skin green. With 75% pure gold, it’s much less likely to cause the reactions you sometimes see with lower-karat gold or metals like copper or nickel. In rare cases, the alloy metals (usually in the remaining 25%) can react with sweat, lotions, or chemicals — but it’s uncommon. To keep your skin and your jewelry looking flawless, just keep your pieces clean, dry, and away from harsh products when possible.

Q: Is 18kt Gold Durable?

Yes — 18kt gold is durable enough for everyday wear. It’s crafted from 75% pure gold blended with 25% alloy metals (like copper or silver), giving it way more strength than softer 24kt gold. That means you get the rich glow of gold, plus the resilience to handle your daily stack.

Q: Can You Wear 18kt Gold Everyday?

Yes, you can wear 18kt gold jewelry every day. It strikes a good balance between durability and purity, making it ideal for daily wear.

Q: How to Clean 18kt Gold?

Keep your pieces glowing with this quick, no-fuss routine:

You’ll need:

Small bowl
Mild soap
Soft-bristled toothbrush
Lint-free cloth

1. Mix your solution:

Add a few drops of gentle dish soap to warm water in a small bowl. Skip harsh cleaners — they’ll do more harm than good.

2. Soak + clean:

Let your 18kt gold pieces soak for 15–20 minutes. Then, use a soft toothbrush or cloth to gently clean them, especially around detailed, hard-to-reach areas.

3. Rinse + dry:

Rinse under lukewarm water to remove soap residue, then pat dry with a soft cloth. Done.

For best results, clean your 18kt gold jewelry regularly and store it in a safe, dry place to prevent tarnishing and scratching.

Q: What Is The Difference Between 14kt And 18kt?

It comes down to gold content and durability:

Gold content: 14kt gold is 58.3% pure gold, while 18kt gold is 75% pure. That extra gold gives 18kt pieces a richer, deeper yellow tone.

Durability: 14kt gold contains a higher percentage of less expensive, alloy metals, making it tougher and more scratch-resistant than 18kt gold.

Bottom line: If you want that luxe gold glow, go 18kt. If you’re hard on your jewelry or need something ultra-durable, 14kt may be the better bet.

Q: What Is The Difference Between 18kt And 22kt?

It’s all about gold content and wearability:

Gold content: 18kt gold is 75% pure gold; 22kt gold is 91.6% pure. While 22kt sounds more luxe, its high gold content can give it an overly saturated, almost orangish tone — a common buyer complaint. 18kt offers a rich, balanced gold hue that’s more versatile for modern jewelry.

Durability: 22kt gold is softer and more prone to scratches and dents, which is why it’s typically used for special occasion pieces — not everyday wear. 18kt gold, with its stronger alloy mix, holds up beautifully for daily life.

Bottom line: If you want fine jewelry you can wear on repeat, 18kt gold is the sweet spot between beauty and practicality.

Wrapping Up:

The takeaway? 18kt gold hits that perfect balance — luxe enough to turn heads, durable enough for the everyday. With its rich glow and lasting quality, it’s a go-to for both statement pieces and jewelry you’ll wear on repeat. Know how to care for it, and your 18kt favorites will stay shining for years to come.
