Short answer
The Jewelry Table sits in the Theology tech tree and guides list its build cost as 4 Wooden Planks, 12 Bronze Nails and 3 Glass. It crafts Zombie Collars, which cost 3, 5 or 10 Faith by tier. A corpse needs a collar to be resurrected, and the collar tier caps how many red skulls the zombie can keep: bronze is the lowest, golden covers up to 10, and steel is used for the strongest builds.

Unlocking and building it
Research the table in the Theology tree, then build it with 4 Wooden Planks, 12 Bronze Nails and 3 Glass. Story guides place one in the Writing Basement, close to where you prepare bodies.
Keep a steady nail supply first; our Bronze Nails and Faith guides cover both inputs.
Collar tiers
Bronze collars come first and only suit low red-skull bodies. The Golden Zombie Collar takes 1 Golden Ingot, 1 Blue Crystal and 5 Faith and allows up to 10 red skulls.
The Steel Zombie Collar is the late-game tier. Combined with improved body parts and Solution for Zombies it is used for the highest-skill zombies.
Guides disagree on the exact skull range of each tier, so check the tooltip in-game before you embalm.
Why the collar matters
A zombie's red skulls set its work skill. Putting a strong body in a cheap collar wastes it, so match the collar to the body before resurrecting at the Resurrection Table.
