Quick answer: Gamma Doppler is the green family of the Doppler finish —
4 phases + Emerald, set by paint index
568–572 on knives (and
1119–1123 on the Glock-18, the only firearm with it). Emerald is the family's gem and trades at
3–4× Phase 2 on big knives; on budget models the multiplier passes 70×.
What is Gamma Doppler?
Released June 15, 2016 in the Gamma Case, Gamma Doppler swaps classic Doppler's pink/blue spectrum for greens and cyans — there is no pink or red anywhere in the family. The paint index table:
| Paint index (knives) | Paint index (Glock-18) | Variant |
|---|
| 568 | 1119 | Emerald |
| 569 | 1120 | Phase 1 |
| 570 | 1121 | Phase 2 |
| 571 | 1122 | Phase 3 |
| 572 | 1123 | Phase 4 |
Just like classic Doppler: the phase is rolled at unbox via the
index (immutable); the seed only shifts texture placement.
How to tell the phases apart
- Phase 1 — bright cyan (in CS2 it almost reads like a blue gem).
- Phase 2 — dark green with cyan highlights; closest to Emerald and the priciest numbered phase.
- Phase 3 — even cyan/green mix; divisive.
- Phase 4 — darker cyan with green accents; near-identical to P3 since CS2's engine change.
- Emerald — vivid, uniform gem green. The family's crown jewel.
Where Gamma Doppler exists
| Source | Items |
|---|
| Gamma Case + Gamma 2 Case (2016) | Bayonet, Flip, Gut, Karambit, M9 Bayonet |
| Operation Riptide Case (2021) + Dreams & Nightmares (2022) | Bowie, Butterfly, Falchion, Huntsman, Shadow Daggers |
| 2021 Train Collection (Sep 2021) | Glock-18 Gamma Doppler — the only gun |
10 knives + 1 pistol. Key Glock detail: as a collection skin its float runs
0.00–0.50 (Battle-Scarred exists, unlike the knives) and there's
no StatTrak version.
2026 prices
Value order: Emerald >> Phase 2 > Phase 1 ≈ Phase 4 ≈ Phase 3. Mid-2026 anchors:
| Item | Numbered phases | Emerald |
|---|
| Karambit Gamma Doppler | P2 ~$2,920; P3/P4 ~$2,000 | ~$8,400 |
| M9 Bayonet | — | ~$7,730 |
| Butterfly | — | ~$9,700+ |
| Shadow Daggers (budget entry) | ~$110 | ~$230 |
| Glock-18 | ~$160–170 | ~$600 (float-sensitive) |
Emerald occupies the same rarity slot as Ruby/Sapphire (Classified grade; community estimates ~5–10% of Gamma rolls — Valve publishes no odds). Like classic Doppler, the October 2025 crash hit the gems hard with recovery through 2026 — distrust guides showing older prices.

How to verify before buying
- Copy the inspect link and read the paint index: 568/1119 = Emerald; 569–572/1120–1123 = P1–P4.
- On the Steam Market all phases share one listing — inspect every unit. Third-party marketplaces (like NTSkins) badge the phase for you.
- A very blue Phase 1 ≠ Sapphire, and a dark P2 ≠ Emerald: the index never lies.
FAQ
Is Emerald worth more than Ruby and Sapphire?
Depends on the knife. Generally same class: on the Butterfly the Emerald (~$9,700) rivals Ruby; on the Karambit, Ruby (~$8,760) still edges out Emerald (~$8,400) in 2026.
Which numbered phase should I buy?
Phase 2 for the best look and resale; Phase 3/4 for the cheapest entry into the family (they're nearly identical visually since CS2).
Does the Glock Gamma Doppler have StatTrak?
No — it's a collection skin (2021 Train Collection): no StatTrak, and float runs down to Battle-Scarred. The FN Emerald is the collector's version (~$600+).
Does Gamma Doppler exist in Field-Tested?
On knives, no (float 0.00–0.08, like classic Doppler). On the Glock, yes — float up to 0.50.
