CS2 Doppler Phases & Gems Guide

Doppler is a knife finish with several randomly-assigned phases. The phase isn't shown in the item name, so you read it from the pattern — and it hugely changes value.

Standard Dopplers

• Phase 1 — heavy black with sharp blue/purple; popular for the dark look.
• Phase 2 — pink and magenta tones.
• Phase 3 — blue with green/teal mixes.
• Phase 4 — mostly blue with minimal black; clean and popular.

The gems (rarest)

• Ruby — full deep red. Very valuable.
• Sapphire — full bright blue. Among the most expensive finishes in the game.
• Black Pearl — dark with a pearlescent swirl (Gamma Doppler only).
• Emerald — full green (Gamma Doppler gem).

Gamma Doppler uses green tones and its own gem set (Emerald / Black Pearl), while regular Doppler uses blue/pink/red with Ruby & Sapphire.
