TL;DR: The gallery is the open area beneath the centre stone. The basket is the structure of metal (often several bars or a solid cup) that holds the stone above the gallery. The bridge connects the setting to the shank. A hidden halo sits within this structure, beneath the stone rather than around it, adding sparkle invisible from above.
Why These Terms Matter
These four components make up the structural core of most engagement ring settings, sitting beneath and around the centre stone. Understanding what each one actually does makes it much easier to follow a CAD design or a jeweller's explanation of why a setting is built a particular way.
The Gallery
The gallery is the open space directly beneath the centre stone, between the setting and the shank. Light enters and exits through this space, which is why an overly enclosed gallery can dull a stone's brilliance — the gallery needs to allow light through, not just hold the stone in place.
The Basket
The basket is the metal structure that actually holds the centre stone, sitting within or around the gallery. It can take several forms: a simple cage of thin bars, a more solid cup-like structure, or an ornate pierced design with decorative detail. The basket's design affects both how much light reaches the stone and how secure the setting feels structurally.
The Bridge
The bridge is the structural connection between the basket and the shank — the part that transitions from the setting itself down into the band. A well-designed bridge distributes stress evenly rather than creating a single weak point where the setting meets the band, which matters more for structural longevity than most buyers realise when first looking at a design.
The Hidden Halo
A hidden halo sits within this same structural area — typically built into the basket or gallery — placing small diamonds beneath the girdle of the centre stone rather than visibly around it from above. From above, the ring reads as a clean solitaire; from the side or in motion, the hidden stones catch light. See our full halo engagement ring guide for how this compares to a standard visible halo, and our hidden halo engagement rings page for design options.
How These Elements Work Together
A well-designed setting balances all four: enough gallery to let light through, a basket that holds the stone securely without overwhelming it visually, a bridge that distributes structural stress properly, and, if included, a hidden halo integrated without compromising the security of the main setting.

Frequently Asked Questions
What is the gallery on an engagement ring? The open space directly beneath the centre stone, between the setting and the shank, which allows light to enter and exit the stone from below.
What is the difference between a basket and a gallery? The gallery is the open space itself; the basket is the metal structure within that space that actually holds the stone.
What is a hidden halo? Small diamonds set beneath the girdle of the centre stone, within the basket or gallery structure, invisible from directly above but adding sparkle from the side or in motion.
