So, you want to buy solid gold. Let's walk through everything you need to know about karats, alloys, and how to spot the real thing so you can build a collection you'll wear for a lifetime.
Solid Gold is…
Timeless
Valuable
Durable
Solid gold is made to be worn often, not saved for a special occasion. It can be cleaned, polished, repaired, and enjoyed for years to come.
Buy nice, not twice. Why buy something you’ll have to replace when you can buy something made to last? Solid gold is durable, valuable, and meant to be worn. Build a jewelry box with pieces you’ll reach for every day, not pieces you’ll forget about when they start to tarnish.
Understanding Gold Karats:
Gold purity is expressed as a fraction of 24. Think of it as “parts pure gold out of 24 total parts.” The higher the karat, the higher the percentage of pure gold. Choosing a karat really comes down to personal taste. If you love a bright, vivid yellow, go for higher karats like 22k or 24k. If you prefer a more balanced tone, 18k or 14k is a great choice.
24k — 99.99% gold: Pure gold is naturally soft and has a bright yellow tone.
18k — 75% gold: Rich in color with a higher gold content. A popular choice for fine jewelry, particularly in Europe.
14k — 58.3% gold: The most popular karat in the United States, offering a balance of gold content, durability, and warmth.
10k — 41.7% gold: The minimum karat generally recognized as gold in the United States. More durable and affordable, with a slightly paler gold tone.
9k– 37.5% gold: Most common in the UK. Affordable option with a pale gold tone.
Understanding Alloys:
Pure 24k gold is beautiful, but it’s also very soft and not always practical for everyday jewelry. That’s where alloys come in. Alloys are other metals mixed with gold to make it stronger and more durable. Common alloying metals include silver, copper, palladium, and platinum.
Those alloys also give gold its different colors. Yellow gold is typically mixed with metals like silver and copper, while rose gold gets its pink tone from a higher proportion of copper. White gold is mixed with white metals such as palladium and silver.
A 14k gold piece is 58.3% pure gold and 41.7% alloy. Those alloy metals help:
- Harden the metal
- Increase durability for everyday wear
- Create the color of the gold
At Yeah It’s Jewelry, we primarily carry 14k and 18k gold—a sweet spot between beauty, durability, and value.
The Price of Gold
The price of gold changes daily based on the global spot price of gold, which is influenced by supply and demand as well as factors like inflation, interest rates, currency strength, and geopolitical events.
The price of an individual piece of gold jewelry depends on more than the market price of gold. Its weight, karat, design, craftsmanship, and rarity all play a role. That’s why the value of a vintage or unusual piece can go far beyond the raw value of its gold.
How to identify your gold:
Already own a piece of gold jewelry and not sure what karat it is? Start by looking for a hallmark—a small stamp that indicates the metal’s purity. You’ll often find it on the back of a pendant, on the bail, or inside a ring band. A jeweler’s loupe can help you spot a tiny or worn stamp.
Common gold purity marks include:
- 14K or 585
- 18K or 750
- 24K or 999
A hallmark is a helpful starting point, but a stamp alone doesn’t guarantee that a piece is genuine. If you’re unsure about a piece or its value, a professional jeweler can test the metal to confirm its karat.
Method 2: Acid Scratch Test
If there’s no hallmark, a jeweler can perform an acid scratch test to help determine the karat of the metal. The jeweler makes a small mark on a testing stone and applies different acid solutions to see how the metal reacts. Acid testing can be a useful way to estimate gold purity, although more advanced testing methods can provide greater accuracy.
Understanding Solid Gold vs. Gold Plated & Gold Filled Jewelry
This is one of the most important distinctions to understand when shopping for gold. Gold-plated and gold-filled jewelry are not solid gold.
Gold-plated jewelry has a thin layer of gold applied over a base metal. The thickness and durability of that layer can vary, but it can eventually wear away with regular use, exposing the metal underneath.
Gold-filled jewelry has a much thicker layer of gold mechanically bonded to a base metal. It contains significantly more gold than gold-plated jewelry and can be more durable, but it is still not solid gold.

Shopping for gold can feel intimidating, but it doesn’t have to be. We want to make buying gold feel exciting, approachable, and easy to understand. At Yeah It’s Jewelry, everything we sell is solid gold, always. That’s our promise.
