Dopplers are among the best-looking and most desirable knives in Counter-Strike. This knife’s skin comes with a variety of color patterns, named Phases. There are seven main variants and you can buy 18 different CS2 Doppler knife models.

Phases of CS2 Doppler knives have some rather common colors, mixed on one blade. The most valuable are one-colored gem-like surfaces. Sure, they are the rarest.

Everything you need to know about Doppler Phases in CS2 has been explained in this article on DMarket Blog.

What Are Doppler Phases in CS2?

In Counter-Strike 2, “Doppler Phases” refer to the different visual patterns that appear on Doppler-patterned knife skins. All knives with this skin have the same name. Each one is categorized into a phase, which determines its color scheme, rarity, and, often, its market value.

Like with some other skins, such as Case Hardened, Doppler is based on a big digital image. The shape of a knife is placed over it to take only a specific part of a larger pattern. If a knife gets into the red corner of the Doppler image during the generation process, it becomes Ruby.

A more common situation is when a blade receives a couple of colors, so it falls into the category of one of the cheaper four Phases.

Beyond the technical explanation, CS2 Doppler Phases are simply color patterns on the knife blade.

Phase 1: Light purple and dark blue
Phase 2: Pink, with small dark purple elements
Phase 3: Deep blue, green, and black
Phase 4: Blue, with small black elements
Ruby: Red
Sapphire: Blue, with purplish shades
Black Pearl: Deep purple

Even if two knives belong to one Phase, they are different. Gradients and darker patterns are placed in unique ways over each blade.

All Doppler Phases

Among the seven possible Phases, the four with no fancy names are the most common (Phase 1, Phase 2, Phase 3 and Phase 4). In terms of CS2 knife prices, they are on the cheaper side.

Compared to CS:GO, Doppler Phases became generally brighter in Counter-Strike 2, thanks to the new lighting system of the new game engine. This upgrade is the most notable on Phase 3 and Black Pearl.

In the following sections, you’ll find more details on all Doppler Phases in CS2.

Phase 1

It’s easy to recognize Phase 1 Doppler thanks to the combination of two main colors: dark blue and light purple, with pinkish shades. Many knives also have black elements, but they are pretty small.

Such CS2 Doppler knives look nice in the game. Still, most players prefer other Doppler Phases, with one-colored blades.

The Finish Catalog number for Phase 1 is #418. The Butterfly knives and the Shadow Daggers have red handles.

Phase 2

CS2 Doppler knives of Phase 2 are mainly pink. The blades may have small dark purple parts.

These are gorgeous knives! Phase 2 Dopplers are bright and shiny. They benefit a lot from the new lighting in Counter-Strike 2. It’s the most popular variant out of the four common Phases of Doppler knives in CS2. The handles of some knife models become purple-red. All Phase 2 Doppler knives have the Finish Catalog number #419.

🔥 The best-looking CS2 knives with Doppler Phase 2: Shadow Daggers, Talon, Skeleton.

Phase 3

These Doppler knives have deep blue as the main color, while green and black parts are often just side elements. Still, having green on the blade is a key feature for Phase 3.

In CS2, this Phase is brighter, so it’s easier to distinguish the color patterns. This has become an immense improvement to the look. Such an upgrade did not affect the popularity of Phase 3, though, and most players prefer other Doppler variants.

Handles of Butterfly and some other knives are green with Phase 3 Doppler. The Finish Catalog number is always #420.

🔥 The best-looking CS2 knives with Doppler Phase 3: Nomad, Survival, Ursus.

Phase 4

The blades of Phase 4 Doppler knives are mainly blue, and only some small parts are black. At first sight, this Phase may resemble Sapphire, but the black elements make a big difference.

Having a consistent color over the knife makes Phase 4 almost as popular as Phase 2.

The blue color is transferred to the handles with Doppler Phase 4. These knives have the Finish Catalog number #421.

🔥 The best-looking CS2 knives with Doppler Phase 4: Butterfly, Bayonet, Huntsman.

Ruby

These Doppler knives are specifically red, and their pattern resembles the structure of a ruby. With some view angles, you can notice dark orange elements on a Ruby Doppler.

Not only are these CS2 knives rare and very expensive, but they also are stunningly beautiful. Red knives fit well with the general aesthetics of Counter-Strike as a bloody shooting game.

Players appreciate the Ruby Phase a lot, and only Sapphire is somewhat more popular in the community. The Finish Catalog number is #415. For the Butterfly knife, this Phase makes the handle dark orange.

🔥 The best-looking Doppler Ruby CS2 knives: Karambit, Skeleton, M9 Bayonet.

Sapphire

Sapphire is the most popular and expensive Doppler Phase in CS2. Sapphire knives look absolutely great in the game! Their blade color is blue, with beautiful purplish shades and the sapphire-like patterns on the surface. With some view angles, you can notice greenish shades as well.

To the knives with changeable handle colors, the Sapphire Phase brings metallic green elements. To make sure you have specifically a Sapphire Doppler CS2 knife, check out the Finish Catalog number: it should be #416.

🔥 The best-looking Doppler Sapphire CS2 knives: Bowie, Karambit, Bayonet.

Black Pearl

Doppler CS2 knives with the Black Pearl Phase are the rarest of them all. However, the rarity doesn’t mean popularity. It’s the least popular knife skin out of the three gem-like Phases.

Black Purple knives are distinguishable by their deep purple blades. Transitions to CS2 made this Phase more beautiful: brighter, and with a cleaner color.

The changeable handles become purple as well. The Finish Catalog is #417.

🔥 The best-looking Doppler Sapphire CS2 knives: Falchion, Butterfly, Paracord.

Market Value and Price Differences

All Doppler knives are unique thanks to a variety of factors. Combined, these aspects affect the market price.

Float Value: Most Doppler knives on the market are Factory New. Knives with a lower Float Value are more expensive.
Demand: The visual appearance is crucial for the price difference between the phases. Phase 2 is the most expensive, while Phase 3 is traditionally on the cheaper side.
Rarity: In addition to a generally better look, Ruby, Sapphire, and Black Pearl are much rarer than the usual Doppler Phase. This makes them very expensive.
Knife Type: Models such as Butterfly, Karambit, Skeleton, and M9 Bayonet are more popular among CS2 players. These Doppler skins are more expensive.
General Look: Knives of one model and one Doppler Phase can be very different from each other due to the very nature of this skin. Those with more dark spots on the blade are cheaper, even within such Phases as Sapphire and Ruby. Cleaner Doppler knives with brighter colors are more expensive.

Tips for Traders and Collectors

In general, investing in CS2 Doppler knives is a good idea. Due to the rarity and popularity in the community, these skins keep their value quite well.

📌 Ruby and Sapphire are the best for long-term investments thanks to their uniqueness and appealing look.

📌 Black Pearl is the least desirable Phase among the gem-like Dopplers. Still, depending on the specific variant, these knives can be very expensive. The highest rarity makes them a good investment option as well.

📌 Phase 2 and Phase 4 are popular in the community, and they are cheap. These knives can be better for shorter investments.

📌 Phase 1 and Phase 3 are the most common Doppler Phases.

It is very important to follow our anti-scam tips for CS2 skins trading! Expensive knives create a high risk of fraud. You can easily avoid any trouble if you make trades and payments via reliable services (DMarket, Steam Market), don’t share your sensitive info, and thoroughly check exactly what knife you are buying.

⚠️ Never make a payment outside the platform you purchase a CS2 knife on.

⚠️ Check URLs of pop-up windows and generally all tabs you open for such transactions.

⚠️ Take a closer look at screenshots: inconsistent lighting reveals fakes. It’s even better to inspect knives in the game before purchasing them.

⚠️ Be mindful of suspiciously good offers. No one sells Sapphire for the price of Phase 3 just because they “need money asap on this card.”

Not at all. Whether you’ve got a Sapphire or a Phase 1, your knife slashes the same way. Phases are purely cosmetic flex — they’re about style, not stats.
