Engagement Ring Basics

The Band

Also known as the Shank

The band — often called the shank — is the circular part of the ring that encircles the finger. It is sized precisely to ensure a comfortable, secure fit. Bands vary enormously in width and profile: some are slender and delicate, others are broader and more substantial. The band can be plain polished metal or decorated with diamonds set along its surface. It is the structural foundation that everything else is built upon.

The Setting

Also known as the Mount

When jewellers and designers refer to the "setting" or "mount," they mean the entire metalwork of the ring — everything except the gemstone itself. This includes the band, the claws, any decorative elements, and the framework that holds the stone. The setting can be kept beautifully plain, relying purely on the metal and its polish, or it can be embellished with additional diamonds or gemstones for extra sparkle and character.

The Centre Stone

The Star of the Ring

The centre stone is the hero of the ring — the primary gemstone that draws the eye and anchors the entire design. For most engagement rings, this is a diamond, though sapphires, moissanites, and other precious stones are also widely chosen. The centre stone is held securely within the setting by a combination of claws and its carefully shaped seat. The shape, size, and quality of this stone are often the first things chosen when designing a ring.

Claws

Also known as Prongs

Claws — sometimes called prongs — are the slim, curved pieces of precious metal that fold over and grip the edges of the centre stone. Their job is twofold: they keep the gemstone firmly in position and provide a layer of protection around its edges. The number of claws can vary; four-claw settings are classic and allow more light to enter the stone, while six-claw settings offer additional security. The shape of the claw tips (rounded, pointed, or flat) can also subtly influence the ring's overall character.

Gallery Rail

Structural Elegance

Positioned midway between the band and the underside of the centre stone, the gallery rail is a horizontal band of metal that adds structural integrity to claw-set rings. It reinforces the connection between the claws and prevents the setting from flexing over time. While primarily functional, the gallery rail can also be a beautiful design detail — particularly when set with small diamonds along its surface to create the effect known as a hidden halo.

Hidden Halo

A Subtle Surprise

A hidden halo is one of the most charming details a ring can have. It consists of a ring of tiny diamonds set into the gallery rail — invisible from above but visible when the ring is tilted, catching the light from the side. The effect is one of secret sparkle: the ring appears clean and classic from the front, yet radiates an unexpected glimmer when seen from a different angle. It's a wonderful choice for those who love understated luxury with a touch of surprise.

Halo

A Crown of Diamonds

Unlike the hidden halo, a traditional halo is fully visible: it is a frame of small diamonds surrounding the centre stone and seen clearly from above. This encircling band of brilliance serves to amplify the visual impact of the centre stone — making it appear larger and more luminous than it is on its own. Halo settings are enduringly popular and suit a wide variety of stone shapes, from round brilliants to ovals and cushion cuts. The halo can be a single row or a double row for even more drama.

Side Stones

Also called Accent Stones

Side stones — or accent stones — are any additional gemstones positioned to either side of the centre stone. They are not there simply to take up space; their purpose is to complement and elevate the main stone, drawing the eye to it and adding depth and movement to the overall design. Side stones can mirror the shape of the centre stone (as in a trilogy ring) or contrast it for visual interest. They may be round brilliants, tapered baguettes, or pear shapes, among many others.

The Bridge

Connecting Everythingk

The bridge is the metal component situated directly beneath the centre stone, connecting the setting above to the band below. It acts as a structural link that holds the ring together as a cohesive whole. While it is rarely seen without a close inspection, the bridge plays an important role in the ring's strength and durability. On some ring designs, the bridge is also a canvas for decorative detail such as engraving or milgrain edging.

Cathedral

Architectural Grace

The cathedral setting takes its name from the sweeping arches of Gothic architecture. In ring terms, it refers to the graceful slopes of metal that rise from the band on either side and curve upward to support and frame the centre stone. This elevated design not only adds a sense of grandeur and height to the stone but also provides protection for its sides. Cathedral settings have a timeless, romantic quality that suits both classic and contemporary styles.

Pavé

A Paved Path of Diamonds

Derived from the French word for "paved," pavé refers to a technique in which small diamonds are set closely together along the band of the ring, held in place by tiny claws or beads. The result is a continuous ripple of sparkle that runs along the shank — typically covering two-thirds of the band's circumference. Pavé is one of the most popular ways to add brilliance to a ring without adding unnecessary bulk, and it pairs beautifully with almost any centre stone setting style.

Turn any engagement ring over and look carefully inside the band — you will find a small stamped mark. This is the hallmark: an official certification that confirms the type and purity of the precious metal used. In the UK, hallmarking is a legal requirement and provides buyers with an independent assurance of quality. Many couples also choose to add a personal engraving alongside the hallmark — perhaps initials, a date, or a short phrase meaningful to them. These small inscriptions transform a beautiful ring into a truly personal keepsake.
