Gold Overview

When choosing jewelry, the metal you select affects more than just looks it determines durability, maintenance, value, and how well your design or gemstone “shows up.” Below is a full breakdown of three of our core metals:


10K Solid Gold

What it is:

10KT (10 karat) gold consists of 10 parts gold and 14 parts other alloy metals, giving it 41.7% pure gold content. Because pure gold is too soft on its own, alloying metals like copper, silver, nickel, and zinc are added to strengthen it.

Exceptional strength & scratch resistance: The higher proportion of alloy makes 10K more robust and less prone to bending or scratching than higher-karat golds.

More affordable: Because it contains less gold, it provides a cost-effective entry into fine jewelry.

Subtle color: Its gold tone is lighter and less intense (more muted yellow) compared to higher-karat golds.
Longevity: With proper care, it’s durable enough for daily wear in rings, bracelets, and earrings.

When to choose it
10KT is ideal when durability and value are top priorities for pieces that are expected to see heavy wear, or where cost sensitivity matters. It’s a practical choice when you want “fine jewelry” features at a more accessible price.


14K Solid Gold

What it is:
14K (14 karat) gold has 14 parts gold and 10 parts alloy metals, meaning about 58.3% pure gold. This blend is a widely accepted standard for fine jewelry because it balances beauty and performance.

Rich, warm gold color: Its higher gold percentage gives a deeper, more classic gold tone favored in engagement rings, necklaces, and heirloom pieces.

Balanced durability: While softer than 10K, 14K still holds up well to everyday use much more so than very high-karat golds (like 18K or 22K).

Popular & trusted: It sits comfortably between price, appearance, and strength which is why many fine jewelry makers use it.

Resists tarnish: Naturally more resistant to oxidation and discoloration compared to lower-gold alloys.

When to choose it
Use 14K when you want a refined gold look with strong everyday performance. It’s ideal for standout pieces like engagement rings, pendants, and anything you plan to keep and wear for decades.


14K Gold Vermeil

What it is:
Gold vermeil jewelry is made by plating a layer of real gold over a sterling silver (925 silver) base. To qualify as “vermeil,” the gold layer generally must be at least 5 microns thick, and the gold should be 10K or higher. Many premium vermeil pieces use 14K gold for the plating, and thicker layers such as 5 microns are often employed to enhance durability and lifespan.

Authentic gold appeal: Because the overlay is real gold (14K), vermeil pieces look real and elegant very close to solid gold in appearance.

Higher quality than standard plating: With a sterling silver base and thicker gold layer, vermeil resists wear and tarnish far better than thin gold-plated pieces.

Cost-effective alternative: You get much of the look of a 14K solid piece at a lower cost because the core is silver.

Hypoallergenic potential: Sterling silver core is often better tolerated than base metals like brass or copper but if the gold layer wears off in spots and exposes the silver, reactions may depend on the specific metal beneath.

When to choose it
Choose 14K vermeil when you want beautiful gold aesthetics without the full cost of solid gold.

 


Solid Gold vs. Vermeil vs. Gold-Plated

In short:

Gold-plated is the most affordable but least durable.

Vermeil improves on plating by using silver beneath and thicker gold it’s a premium “mid-tier” alternative.

Gold-filled offers the thickest, most durable gold layer (next after solid gold), making it ideal for long-term wear when solid gold is too pricey.

Not to be confused with a diamond's carat (weight), a gold's karat (K) is determined by the proportion of pure gold vs. alloys added to strengthen it. Gold purity is measured in karats; the highest karat number is 24K, which is the karat of pure gold. Since pure gold is too soft to be used in jewelry making, gold is mixed with other metals, which make the resulting alloy harder and more durable as jewelry. A higher percentage of pure gold to alloys equals a higher Karat. To determine what gold karat a piece of jewelry is, look for the gold stamp that's on the inner edge of a gold ring. For example:
  • 10 karat gold is an alloy made up of 10 parts gold + 14 parts other metals
  • 14 karat gold is an alloy made up of 14 parts gold + 10 parts other metals
  • 18 karat gold is an alloy made up of 18 parts gold + 6 parts other metals
Visually the differences among the different karats is subtle, and the polish used on jewelry can be misleading. To verify the gold Karat of jewelry, you must have jewelry tested in a nationally certified independent lab as informal tests such as scratch testing and acid testing are prone to human error.

Karat vs. Carat


Is 10K or 14K Better?

Carat refers to the weight of a diamond, whereas Karat, refers to the pure gold content in jewelry.

In some parts of the world, gold jewelry with a higher karat, such as 18K and 22K, is more is widely sought after. But in the U.S., most people opt for 10K and 14K gold; these varieties are stronger and more affordable than those with higher pure gold content.

My Trio Rings offers both 10K and 14K gold options for all our diamond ring sets. But what’s really the difference between the two?

Is 10K Lower Quality?

You'll notice that 10K jewelry is less expensive than 14K pieces. This makes sense, since 10K jewelry contains less gold. However, keep in mind that in this case, cheaper doesn't mean low quality: 14K gold may be more expensive, but its higher gold content also makes it softer and less durable than 10K gold.

Gold Color

Gold is most often found in yellow, white and rose colors. Since all gold jewelry is made by mixing pure gold with alloys (other metals), this combination of metals is what determines a gold's final shade.

Do Gold Rings Fade?

It's a common misconception that rings which fade are not authentic. But it's not the gold itself that fades - it's the polish that all gold jewelry has on its surface which gives it the lustrous shine. It's important to take gold jewelry in for a "tune-up" from time to time to get a new coat of rhodium, yellow polish or rose polish. Many jewelers also refer to this practices of having gold rings "redipped" which references how rings are dipped into an electroplating solution which is how polish adheres to the gold surface.

Nickel Allergies

Nickel is commonly used in gold alloy mixtures and is also a metal that many people are allergic to. For people with this sensitivity, jewelry made with nickel can cause a skin reaction or rash if the gold polish fades over time.
