The short answer: in Britain a man's signet ring is traditionally worn on the little finger of the non-dominant hand, which for most people means the left. That is a convention, not a rule. Antique signet rings have been worn on the index finger, the ring finger and even the thumb, and today the right finger is simply the one where the ring fits well and feels like yours. Here is how we advise customers on choosing the finger, getting the size right and wearing an antique men's signet ring every day.
Why the little finger?
For most of their history signet rings were tools. The engraved head, cut in reverse, was pressed into hot wax to seal letters, deeds and documents, and a seal was as good as a signature. Worn on the hand you did not write with, the ring was out of the way of the pen and ready to press into the wax once the letter was folded. The little finger also kept a broad, heavy head clear of the other fingers, and left the ring finger free for a wedding band.
The habit hardened into etiquette in Victorian and Edwardian England, when gentlemen's signets were made in large numbers in Birmingham and Chester and worn by men of every profession, not only the landed gentry. By then few men sealed their own letters, but the little finger of the left hand had become the accepted place for a family ring, and it remains so in Britain. For the wider history, from Roman seals to Victorian crests, see our buyer's guide to antique signet rings.

Which finger? The options, and what they say
The little finger (pinky)
The classic choice for a men's signet ring, and the one we see most often. It suits stone-set seals and small oval heads particularly well, and it pairs comfortably with a wedding band and a watch. Many of the Georgian and Victorian rings that pass through our hands are pinky sizes, because that is how they were worn. Our Victorian 18ct gold banded agate signet of about 1870, at UK R½ / US 8¼, is a typical gentleman's pinky ring of the period.
The ring finger
On the Continent a signet ring is often seen on the ring finger, and some men wear one there in place of, or alongside, a wedding band. In Britain a ring on the third finger of the left hand will usually be read as a wedding ring, so if that is not the message you want, the right hand or the little finger is the safer choice.
The index finger and thumb
Look at Renaissance portraits and you will see signet rings worn on the index finger and even the thumb, often several to a hand. Large medieval and Renaissance seal rings were frequently made to be worn this way, which is one reason so many of them are generous sizes. A big ring on the index finger is a confident look today and works well with the heavier antique pieces, such as our medieval Duhamel silver signet of about 1480, a large UK V / US 10½.
Left hand or right?
Tradition says the non-dominant hand, which keeps the ring away from the knocks of daily work. In practice many men wear a signet on the right hand so that it does not compete with a wedding ring, or on whichever hand they wear their watch so that the gold or metals match. There is no wrong answer; the ring should simply feel natural.
Which way should the crest face?
This is the question we are asked most often after "which finger", and the honest answer is that families differ. A crest or monogram is usually engraved upright to the wearer's eye, running along the finger. Some old families prefer it set to read the right way up for someone looking at the hand. On a stone-set seal or intaglio, such as our Victorian carnelian intaglio ring with the laureate head of a Roman emperor, the image is usually cut to sit upright as you look down at your hand. Wear it the way it was made.

Sizing an antique men's signet ring
Getting the size right matters more with a signet than with almost any other ring. The heavy head wants to roll round to the palm side if the ring is loose, and a ring that is too tight on the little finger quickly becomes uncomfortable.
Measure the finger you will actually wear it on
A little finger is usually several sizes smaller than the ring finger of the same hand, so do not order a pinky ring in your wedding-band size. The best method is to have the finger measured by a jeweller with a set of ring gauges, ideally at the end of the day when fingers are at their largest. British sizes run in letters (a man's pinky is often somewhere around M to Q, and a ring finger around R to V) and American sizes in numbers; we give both in our listings.
Allow for the width of the band
A broad, heavy shank fits more snugly than a slim one of the same nominal size. For a wide signet many men prefer half a size larger than they would take in a slim band. The ring should slide over the knuckle with a little resistance and sit without spinning.
Can an antique signet ring be resized?
Usually, yes. A solid gold shank can normally be made larger or smaller by a skilled jeweller, and a neat old resizing is perfectly normal on an antique signet; our banded agate signet shows one. There are exceptions. Rings with decorated shoulders need care so that the ornament is not distorted, very old silver may need strengthening first, and some materials cannot be altered in the usual way at all. Our Berlin iron signet ring of about 1820, cast in iron during the Napoleonic Wars, is a case in point: iron cannot be stretched or soldered like gold, so it is a ring to buy in your size, and at UK Y½ / US 12¼ it is a rare large one.

How to wear an antique signet ring today
With a wedding ring
The traditional arrangement is a wedding band on the ring finger and a signet on the little finger of the same hand. If the two rings rub, move the signet to the other hand. Mixing yellow gold with a platinum or white gold band is perfectly acceptable; antique jewellery has always mixed metals.
One ring, or several?
A single good signet says more than a handful of rings. If you want to wear two, keep them on different hands and let one be clearly the main piece. An antique ring with a story, such as our Victorian hidden key ring of about 1870, whose hinged head opens to reveal a tiny Bramah key, does not need competition.
Plain, crested or stone-set?
You do not need a family crest to wear a signet ring. Many of the most handsome antique men's signet rings are set with an uncarved hardstone such as agate, bloodstone, carnelian or onyx, or with a classical intaglio. Some men have their own initials or device engraved on a plain head; others prefer to wear an old ring with someone else's crest, as a piece of history in its own right. We would always advise keeping original engraving rather than polishing it away. Our guide to bloodstone signet rings and our collector's guide to intaglio rings explore the stone-set options further.
Looking after it
An antique signet ring was made to be worn, and gentle daily wear suits it. Take it off for heavy lifting, gardening and the gym, and keep it away from chlorine. Clean gold with warm soapy water and a soft brush, but do not soak stone-set rings, which can trap water behind the stone. Iron and old silver should be kept dry and simply wiped with a soft cloth. As with any fine antique jewelry, have the ring checked by a jeweller every few years, particularly the setting of any stone.

Frequently asked questions
Which finger should a man wear a signet ring on?
Traditionally the little finger of the non-dominant hand, usually the left. The ring finger, index finger and right hand are all perfectly acceptable; choose the finger where the ring fits and feels comfortable.
What does a signet ring on the pinky mean?
Historically it showed that the wearer had a seal of his own, usually bearing a family crest or initials. Today it is simply the classic way to wear a signet, and it carries no special meaning beyond that.
What size signet ring should I buy?
Have the finger you plan to wear it on measured, as a little finger is usually several sizes smaller than a ring finger. For a wide, heavy band, consider half a size larger.
Can I wear a signet ring with someone else's crest on it?
Yes. Many collectors wear antique signets engraved with an unknown family's crest or initials and enjoy them as pieces of history. Original engraving adds to an antique ring's interest and should be kept.
Can women wear men's antique signet rings?
Of course. Signet rings have never been men's jewelry alone; many were worn by both men and women, and a gentleman's pinky ring often makes an ideal size for a woman's index or middle finger.
