Emerald is the top tier of the Gamma Doppler series, the rare case where the marbled metallic coat comes out fully saturated green across the blade rather than only in patches. On the M9 Bayonet that means an almost solid deep-green finish, which is exactly why these emerald pulls are so scarce and prized.

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.
