Pendant vs Necklace vs Locket: What’s the Difference?

You discover a piece of jewellery that catches your eye.

One website calls it a pendant. Another calls something almost identical a pendant necklace. Then a locket appears, and suddenly three very familiar words start feeling unnecessarily complicated.

The good news?

The difference is actually quite simple.

A necklace is the complete piece of jewellery worn around your neck. A pendant is the decorative element that hangs from a necklace or chain. A locket is a particular type of pendant that typically opens to hold something small and personal inside.

So yes, one piece of jewellery can technically be more than one of these things at the same time.

Here’s how to tell them apart.

What Is a Necklace?

A necklace is the broadest term of the three.

If a complete piece of jewellery is designed to be worn around your neck, it can be described as a necklace. It might be a simple chain, a stone-set design, a layered style, or a chain carrying a pendant.

And importantly, a necklace does not need a pendant.

A necklace can consist of just a chain, without any additional features. It can also feature decorative details along its entire length.

This is often where the misunderstanding begins. When you buy a pendant necklace, you are still buying a necklace—the pendant simply describes the focal detail hanging from it.

Think of a necklace as the overall category. Pendant and locket tell you more about what is happening within that necklace. 

What Is a Pendant?

A pendant is an ornamental piece designed to hang from a necklace chain.

It could be a heart, star, solitaire stone, cross, evil eye, teardrop, initial, geometric shape or almost any other design.

The pendant often draws attention first because of its distinctive design.

Some pendants can be paired with different chains, while others are permanently attached to the necklace. 

This also explains the difference between a pendant and a pendant necklace.

A pendant refers to the hanging ornament itself.

A pendant necklace refers to the complete piece of jewellery, including both the chain and the pendant.

Small distinction.

Useful distinction.

Especially when you are shopping online and need to know whether you are buying just the pendant or the complete necklace.

What Is a Locket?

A locket is a pendant that features a small, usually hinged compartment for storing keepsakes.

Traditionally, this space might hold a photograph, tiny portrait, note, or another small memento.

This feature distinguishes a locket from an ordinary pendant.

A heart-shaped pendant and a heart-shaped locket may look very similar from the outside. The key difference is that a locket has an interior space where a small item can be kept.

Because of this personal element, lockets often carry sentimental value. They are popular choices for birthdays, anniversaries, and other occasions when jewellery is meant to express a personal connection rather than simply complement an outfit.

Pendant vs Necklace vs Locket: What Is the Main Difference?

Here is the easiest way to separate them:

And there is one relationship worth remembering:

A locket can be a pendant, and a pendant can be part of a necklace—but not every necklace has a pendant, and not every pendant is a locket.

That one sentence clears up most of the confusion.

Why Are Pendant and Necklace Used Interchangeably So Often?

Because in everyday shopping, people usually talk about the complete piece rather than separating every component.

If someone says, “I bought a heart pendant,” they may actually mean they bought the heart pendant with its chain.

Technically, that complete piece is a pendant necklace.

But normal conversation does not always follow jewellery terminology perfectly—and it does not need to.

Where the distinction becomes useful is when you are buying online.

If a product is described simply as a “pendant,” check whether a chain is included. Look at the product images and description instead of assuming.

For a locket, check whether it actually opens or whether “locket” is simply being used loosely to describe the shape.

Those small details can prevent a very annoying surprise when the order arrives.

Which Should You Choose: a Pendant, Necklace or Locket?

That depends less on terminology and more on what you want from the piece.

Choose a pendant necklace if you want one clear focal point and something easy to repeat with everyday outfits. Pendants are especially versatile because the design can add personality without making the entire necklace feel heavy.

Choose a plain or detailed necklace without a pendant if you prefer the chain or overall necklace design to be the focus. These also work well for layering.

Choose a locket when the sentimental element matters. It is particularly suited to meaningful gifts or jewellery that carries a personal memory.

And once you have chosen a pendant, placement matters too. Our guide on how to style pendant necklaces for different necklines explains how necklace length and pendant shape interact with what you wear.

What Should You Check When Buying a Pendant Necklace or Locket Online?

Do not stop at the product name.

Check the chain length, pendant dimensions, material, clasp, weight and whether the chain is included.

For pendants, check whether the pendant is fixed or movable and whether its size suits the kind of jewellery you normally wear.

For lockets, check how the opening mechanism works and whether the design is actually intended to hold something inside.

Wearability matters too.

A beautiful piece that constantly flips, feels too heavy or sits awkwardly against your usual necklines will spend far more time inside your jewellery box than around your neck.

So, Is a Pendant the Same as a Necklace or Locket?

Not exactly.

A necklace is the complete neck-worn piece. A pendant is a decorative element that hangs from it. A locket is a type of pendant that typically opens and holds something personal inside.

Once you understand that relationship, the terminology stops being confusing.

More importantly, you know what to look for when you shop.

Because whether you choose a simple pendant, a sentimental locket or a necklace that needs no pendant at all, the best piece is the one that makes sense for how—and why—you actually want to wear it.
