Onyx and Brass Desk Set with Rolling Perpetual Calendar and Twin Pen Holders, c. 1950–1970

The Piece

A desk set built on a single slab of banded onyx — milk white shot through with drifting bands of honey and amber, no two inches alike, polished to a soft glassy sheen. The stone is the whole foundation: heavy enough that nothing on it shifts, and cool to the touch in a way no substitute manages.

Mounted across the back is a rolling perpetual calendar, a brass barrel capped at both ends in chrome, with three small windows reading day, date, and month. Thumb the chrome end caps and the drums turn inside, clicking through TUE to WED, 8 to 9, SEP to OCT. It is a mechanism with no battery, no cord, and nothing to fail — you simply move it forward each morning, which is the small daily ritual that makes people love these.

At each end, a black tapered pen funnel rises from a turned brass collar, angled outward so a pen sits ready rather than flat. Between them, an oval brass plate is set flush into the stone, left blank for engraving. The underside is finished in green baize.

History & Provenance

The onyx desk set belongs to the executive office of the mid-twentieth century, when a desk was a statement of position and the objects on it were chosen accordingly. Sets like this were the standard gift for a promotion, a retirement, or a twenty-fifth anniversary with a firm — which is exactly why so many carry an engraved plate, and why this one, left blank, is the more useful version.

The stone is banded onyx-marble, quarried and worked in Mexico, Italy, and Pakistan through these decades and shipped worldwide for exactly this purpose. The rolling perpetual calendar is the older idea: mechanical desk calendars of this drum type date to the nineteenth century and were still being made through the 1970s, long enough that they became shorthand for a certain kind of office. This example carries no maker's mark, which is normal for the category — these were sold under retailer and gift-house names rather than manufacturer marks.

Why It Belongs in Your Home

A working desk deserves one object that isn't plastic, and this is it. The calendar earns its place by requiring something of you — a few seconds each morning to advance the date, which is a better way to start at a desk than looking at a screen. The stone anchors a corner of the surface and stops paper from wandering, and the pen funnels keep two good pens upright and reachable instead of rolling into a drawer.

It also reads beautifully in a room that isn't an office. On a console, a shelf, or a bedside table it works as sculpture, and the white-and-honey stone sits naturally with brass, walnut, leather, and cream. The blank oval is a genuine opportunity: engrave a name, a date, or nothing at all. A note on care: onyx is softer than granite and porous, so wipe it with a barely damp cloth rather than any cleaner, and never let alcohol, citrus, or vinegar sit on it — they etch the polish permanently. Leave the brass to its patina, or bring it up with a proper metal cream on a cloth, keeping it off the stone.
