The Ursus, a no-nonsense tanto with a faceted blade and impact pommel, here reaches the top of the Doppler chase: Ruby. Instead of the usual blue-and-black marble, the candy coat over the marbleized base resolves into a deep translucent red across the faceted steel. It's one of the rare Doppler pulls and sits at the ceiling of the line.

Doppler phases
Doppler and Gamma Doppler are split into phases. Standard Doppler has Phase 1–4 plus the rare Ruby (red), Sapphire (blue) and Black Pearl. Gamma Doppler adds Emerald as its top phase.
The phase is part of the item and changes both the look and the value — Ruby, Sapphire, Emerald and Black Pearl trade well above the numbered phases. On this page the phase is shown in the name and selectable where variants exist.
