The Emerald is the top tier of the Gamma Doppler line, where the marbleized metallic base coat happens to cure into an almost fully green blade. That deep, even emerald color is rare across the Flip's back-swept Persian blade, which is why it sits well above the standard phases. It is a Doppler-family finish judged entirely on how much pure green the candy coat reveals.

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.
