Object
Platinum Signet Ring
A heavy platinum ring with a wide, flat bezel engraved with Hyde's personal sigil—a stylized alchemical symbol denoting temporal inversion. Its surface bears faint scratches from years of use, and a small chip is visible where the sigil meets the band. Ruth initially handles it with medical caution before placing it on the work surface, while the Doctor absentmindedly spins it between his fingers during technical explanation. The Brigadier ignores it entirely, dismissing Hyde's personal effects as irrelevant clutter.

Purpose
No explicit functional purpose is shown beyond serving as Hyde's identifying personal item.
Significance
The ring functions as Hyde's emblem of authority within his apartment, but its inclusion among scavenged materials demonstrates its lack of importance to the Doctor's attempted solution. Its abandonment alongside the failed device underscores the futility of their attempts to counter the Master's accurate temporal manipulations.
