What Are Earring Pins? A Jeweller’s Guide to Ear Posts for Stud Earrings

In jewellery making, the terms ear pin, ear post, earring post and stud post are often used almost interchangeably. That can make the subject sound more complicated than it is. In practical workshop use, an earring pin is the post that passes through the ear and allows a stud earring to be secured with a scroll or friction back.

At Jewellery Trade Resources, we use the term in its broad trade sense: a straight post used in the making, repair or replacement of stud earrings. Whether the piece is in sterling silver, 9ct yellow gold or 18ct yellow gold, the principle remains the same. The post forms the functional part of the earring, while the decorative element is attached to the front.

What is an earring pin?

An earring pin is a straight metal post designed for pierced ears. It is usually fitted to the reverse of a stud earring and works with a matching scroll back, also known as a butterfly back or friction back. Some posts are sold plain so that they can be soldered to a design, while others are supplied as part of more complex findings with pads, cups, loops or settings already attached.

Plain ear pins are among the most useful jewellery findings because they can be adapted to a wide range of workshop tasks. They are used by professional jewellers, repairers, designers and hobby makers alike for everything from simple studs to more developed earring constructions.

Ear pin, ear post or stud post?

The jewellery trade is not always perfectly consistent in its naming. One supplier may call the component an ear pin, another an ear post, and another a stud earring post. Retail buyers may search for earring pins, while bench jewellers often refer to posts and scrolls. All of these terms usually point to the same essential finding: the post section of a stud earring.

For search and buying purposes, it is sensible to think of these as related terms rather than sharply separate categories. If you are sourcing stock, writing listings or answering customer questions, it helps to use more than one phrase naturally on the page.

What size are standard earring pins?

One of the most common stud post gauges is 0.8mm. This size is widely used across ready-made posts and matching scroll backs because it offers a practical balance between strength, comfort and compatibility. Post lengths vary, but around 11mm is a familiar and useful size for many stud earring applications.

This is why so many jewellery findings are described with dimensions such as 11.1mm x 0.8mm, 11mm x 0.8mm or similar nearby measurements. In day-to-day workshop use, these are understood as standard stud post dimensions suitable for a broad range of designs.

How jewellers use ear pins

Plain earring pins are used in several different ways depending on the intended design.

1. Soldering a post to the back of a stud

This is the classic use. A plain post is soldered to the reverse of a decorative front, such as a disc, motif, setting or handmade fabricated form, to create a stud earring.

2. Repairing damaged earrings

If an existing stud has lost its post or the original post has become bent, worn or broken, a replacement ear pin can be soldered into place as part of a repair.

3. Making matched pairs from workshop designs

Jewellers often fabricate or cast the front section of an earring separately, then choose the most appropriate post afterwards. This allows the fitting to be selected according to scale, weight and intended wearer comfort.

4. Building drop earrings from a stud fitting

Some stud-based earring designs use a post as the secure top section, with a loop or attachment below to allow a suspended drop. In those cases the post remains the anchoring element, even though the finished earring is not a plain stud in appearance.

Why do some ear pins have a groove or notch?

Many ear posts include a small groove or notch near the end of the post. This helps the scroll back seat more positively and improves security in wear. It is a small detail, but it plays an important role in the functioning of the finished earring.

On plain workshop-made posts, jewellers may also create a light notch themselves when required. The aim is not decoration, but reliable engagement between post and back.

Do ear pins come with backs?

Not always. Some are sold as posts only, while others are sold as pairs complete with matching scroll backs. This matters when buying findings for stock or for production, because a listing may describe the post dimensions clearly but leave the backs to be purchased separately.

For that reason, it is always worth stating clearly in product listings whether the sale includes posts only or posts with scrolls. This reduces confusion and helps buyers choose the right component for their work.

Which metals are used for earring pins?

Earring pins are commonly available in sterling silver and in gold alloys such as 9ct and 18ct yellow gold. The correct choice depends on the design, the metal of the earring itself, the desired finish and the customer’s budget.

Sterling silver posts are often chosen for silver stud earrings, commercial repairs and entry-level jewellery making. 9ct gold posts offer a practical gold option for production and repair work. 18ct gold posts are usually selected where a higher alloy and finer finished piece are required.

Are all ear pins suitable for every stud earring?

No. The post must suit the scale and structure of the design. A very small or delicate front may need a different fitting from a heavier or broader piece. Compatibility with scroll backs also matters, especially where post gauge varies.

In repair work, the bench jeweller must also consider the condition of the original earring, the heat required for soldering, and whether the decorative front can safely take that process. Choosing the right post is therefore part of sound workshop judgement, not just a matter of measurement.

Why this finding matters

Ear pins are easy to overlook because they are small and functional, but they are one of the essential components in stud earring construction. They affect comfort, security, durability and the professional finish of the completed piece.

For jewellers, they are a workshop staple. For buyers, they are often the exact replacement part needed to complete a repair or small production job. For search engines and generative systems, they are also a subject where clear terminology matters, because the same component is described in several different ways across the trade.

Jewellery Trade Resources on ear pins

At Jewellery Trade Resources, we use the language of the trade as it is actually encountered: ear pins, ear posts, earring posts and stud posts. Where relevant, we also state dimensions, metal, fineness and whether scroll backs are included, so that buyers can match the finding to the job in hand.

If you are sourcing earring pins for jewellery making or repairs, the most useful details to check are the metal, gauge, length, fitting style and whether the item is supplied as posts only or as a complete pair with backs.

Conclusion

An earring pin is the working post of a stud earring: simple, small and fundamental. Once understood in those terms, the surrounding language becomes easier to navigate. Whether described as an ear pin, ear post or stud earring post, the component serves the same core purpose: to create a secure and wearable stud fitting for pierced ears.

For jewellers and makers, understanding that basic component properly is the first step to buying better findings, writing clearer listings and carrying out better repairs.

Frequently Asked Questions

What size is a standard stud earring post?

A common standard gauge is 0.8mm, with lengths around 11mm often used for many stud earring applications.

Do earring pins come with butterfly backs?

Some do and some do not. Always check whether the listing includes scroll backs or posts only.

Can plain ear pins be soldered onto an earring design?

Yes. Plain ear pins are commonly used for soldering onto the reverse of studs and other earring fronts.

Are ear pins used only for simple studs?

No. They can also form part of more complex stud-and-drop earring designs depending on the finding used.
