CS2 Doppler Phases Explained: Phase 1 to 4, Ruby, Sapphire, Black Pearl and Emerald

Each finish comes in phases with different colors: Doppler has Phase 1 to 4, Ruby, Sapphire and Black Pearl, and Gamma Doppler has Phase 1 to 4 and Emerald. On the same knife, the phase changes the price far more than the wear does.

This guide shows what every phase looks like, how to tell them apart, which knives have each finish and how the phases compare in price, with SkinsMonkey prices checked on November 2, 2026.

Our WIKI lists every phase of all knife skins as a separate item with its own price.

On November 2 a Factory New Karambit | Doppler Phase 3 cost $1,660.32 and a Karambit | Doppler Ruby cost $9,764.67, while the Minimal Wear copy of the same Phase 3 was less than two dollars cheaper.
