Doppler: Phase 1 to 4 and the three gems
Doppler knives come in four regular phases plus three “gem” variants. The regular phases mix black, pink, purple, blue and green in different proportions; Phase 2 is the pink-heavy one most players picture when they think of a Doppler. The gems are single-colour and rare: Ruby (red), Sapphire (blue) and Black Pearl (dark purple-black).

FAQ
What are Doppler phases in CS2?
Doppler and Gamma Doppler knives come in several colour variations called phases. Each phase is technically its own finish with its own paint index, so the same knife can look and cost very differently depending on the phase.
Which Doppler phase is the most expensive?
The gem phases (Ruby, Sapphire and Black Pearl for Doppler, Emerald for Gamma Doppler) are far rarer than Phase 1-4 and usually sell for several times more. Among regular phases, Phase 2 usually carries a premium for its pink colour; the table below shows the current price of every phase.
Does float matter on Doppler knives?
Doppler and Gamma Doppler only exist in Factory New and Minimal Wear, so wear is never heavy. Most buyers prefer Factory New, but the phase has a much bigger effect on price than the float.
