Women's Signet Rings - 18 Carat Gold

Women’s 18 carat gold signet ring: the criteria that matter

A signet ring is chosen first by its hallmark. 18 carat gold corresponds to a 750/1000 alloy, meaning 75% pure gold combined with copper, silver or palladium depending on the desired shade: yellow, white or rose. 9 carat gold (375/1000) also exists on the market, less rich in gold, so lighter in yellow tone and more resistant to everyday knocks, but less sought after for a piece meant to last several decades.

The plate, oval or square, changes how the jewel reads on the hand. An oval plate visually elongates the finger and suits slender hands; a square plate, wider, showcases a complex heraldic engraving or a multi-quartered coat of arms better. Between the two shapes, the thickness of the band also plays a role: a thin band (1.5 to 2 mm) stays discreet under other rings, while a wider band (3 mm and above) asserts the jewel as a centrepiece. To compare the two approaches, the plain solid gold signet ring and the stone-set version serve different purposes.

What signet ring size should a woman choose

Measuring your finger size

Women’s ring sizes most often range between 48 and 65, the measurement corresponding to the circumference of the finger in millimetres. A jeweller can take it in a few minutes with a set of ring sizers; failing that, a flexible ribbon wrapped around the finger and then measured against a ruler gives an approximate value, to be checked before any final purchase since the fit determines how comfortable the ring is to wear.

Weight, a reliable benchmark

A women’s signet ring weighs on average 2 to 3 grams of gold, compared with 4 to 5 grams for a model designed for a man’s hand. Some wide-plate or stone-set models exceed 10 grams, band and stone included. This figure remains a useful indicator for comparing two pieces that look visually similar.

Which finger to wear a women’s signet ring on

The left little finger, the most common practice in France

Wearing the signet ring on the little finger of the left hand remains the most common practice in France, inherited from the customs of families bearing a coat of arms. This choice also has a practical reason: the little finger is the finger that gets in the way least in everyday life for a piece of jewellery worn permanently, unlike the index or middle finger, which are used more.

The right hand, a matter of preference

Nothing requires the left hand. Many women wear their signet ring on the right, particularly when the left hand is already occupied by a wedding band or engagement ring. The choice comes down to personal preference rather than a strict rule.

18 carat gold signet ring or stone-set signet ring: what’s the difference

The solid 18 carat gold signet ring relies on the simplicity of the metal alone, engraved with initials or a coat of arms on the plate. The stone-set version adds a plate in lapis lazuli, carnelian, garnet or citrine, on which the engraving stands out through colour contrast rather than through the relief of the metal alone. The choice mainly depends on what you want to highlight: the engraving alone stands out better on polished gold, while a coloured stone catches the eye even before the motif is read. The semi-precious stone-set signet ring thus differs clearly from a plain solid gold piece, including in terms of care: a stone requires avoiding direct knocks, which gold alone withstands better.

Engraving your women’s signet ring: initials or coat of arms

The space available on the plate

A signet ring plate most often measures between 10 and 14 mm wide. This surface limits the engraving to a few clean letters rather than an elaborate design: two or three interlaced initials remain legible, while a multi-quartered coat of arms requires a wide plate and fine engraving, achievable but requiring greater precision in the design before execution.

Initials, monogram or family coat of arms

Engraved initials remain the most legible option on a small plate. The coat of arms or crest, on the other hand, follows precise codes specific to heraldry (division of the field, charges, colours) and is generally passed down as is within the same family. A young woman bearing her family’s coat of arms can, on her wedding day, combine it with her spouse’s if he also has one. To place these choices in context, the guide page for choosing your signet ring details the possible combinations between plate, material and engraving.

Women’s signet ring and men’s signet ring: what changes

Beyond the weight already mentioned, the overall proportions differ: a wider plate, a thicker band and often a more elaborate engraving on models designed for a man’s hand. The wearing conventions remain similar, with the little finger leading, but the choice of plate, oval for delicacy or square for asserting the coat of arms, applies to both. The men’s signet ring thus shares the same personalisation logic, with dimensions suited to a larger hand.
