Engraved Gemstone Signet Rings

Hand-engraved carnelian, sardonyx, agate and bloodstone rings. Made to order.

A gemstone signet ring is engraved directly into the stone, in the traditional way of an heraldic seal. You can choose how your stone is engraved. Engraved for seal, the design is cut in reverse, so it prints the right way round in wax. Engraved for show, the design reads correctly on the ring itself, so a motto or lettering can be read as the ring is worn. Each ring is a bespoke commission, made on any signet ring head size and shape, in gold, silver or platinum. See the shapes and sizes in choosing your signet ring.

Our senior master craftsman William Wright has 50 years' experience as a heraldic seal engraver on gold and gemstone rings, and engraves gemstone rings full time. His son Simon, head engraver and managing director of Dexter Rings Ltd, has hand engraved signet rings for 30 years and concentrates mainly on precious metal.

Because of the technical complexity of gemstone engraving, we don't offer a buy-now service. Each ring is quoted individually. Tell us what you would like engraved, your preferred stone and metal, the head size and where you are in the world, and we will send you a gemstone signet ring quotation. If you would prefer to buy today, see our full gold signet ring range.

Gemstone Signet Rings by Stone

The stones below are the traditional choices for engraved seals. Each is hard-wearing enough for a ring, and each gives a different look to the engraving. If you're unsure which suits your design, tell us in your quote request and we'll advise.

Sardonyx Signet Rings

Sardonyx is banded stone with layers of colour, usually red over white or blue over black. The engraver cuts through the top layer so the design shows in contrast against the layer below, which gives coats of arms and crests real definition. It is one of the most popular choices for heraldic rings.

Carnelian (cornelian) Signet Rings

Carnelian, also spelled cornelian, is a translucent orange-red stone and the classic seal stone, used for signets since ancient times. Usually set in an open-back mount, so light passes through the stone and shows off the detail of the engraving.

Agate Signet Rings

Agate is available in several colours, including the blue and green agates used on our rings. It is a fine-grained stone that holds crisp detail, and suits crests, insignia and monograms.

Onyx Signet Rings

Black onyx gives a bold, dark, formal, masculine look. Engraving shows as subtle shading against the stone, which works well for simple, strong designs such as a lion, a griffin or a monogram.

Bloodstone Signet Rings

Bloodstone is a dark green stone flecked with red, with a long history as a gentleman's signet stone. It has a distinctive, understated character.

Lapis Lazuli Signet Rings

Lapis lazuli is a deep blue stone, striking for simpler engraving. It is softer than the other stones here, as such not suitable for really fine detail of a coat of arms. Additionally the lapis ring should be worn with some care.


Open-Back or Closed-Back?

Opaque gemstones are supplied set within closed-back rings. For translucent stones such as carnelian, we recommend open-back mounts in the traditional style, which let light pass through and show off the stone and the engraving.
