Fade and Doppler are the two most recognizable gradient finishes in CS2, but they work in fundamentally different ways: Fade's color depends on the fade percentage set by that copy's pattern index, while Doppler's look comes from one of four fixed phases or three far rarer gems. The knife versions of both finishes share a trait: a float range from 0.00 to 0.08 means they only exist in two conditions, Factory New and Minimal Wear — the lower conditions were simply never released for them. The price range is enormous: from around $100 for an ordinary Doppler phase on compact models like the Navaja Knife up to $17,000 for a ★ Butterfly Knife | Doppler in Black Pearl. Below we break down how each finish is priced, which knives carry them, and which one fits your budget and taste.
Fade: What Sets the Price
Fade is a rainbow gradient that runs from yellow through pink and purple to blue; on a knife it sits near the handle and fades out toward the tip. How much of the blade the gradient actually covers is set by the so-called fade percentage, a value derived from that copy's pattern index: as a rule, the higher the fade percentage, the higher the collector demand and the potential premium, though the exact premium depends on the knife model and the market. Copies with close to 100% coverage are noticeably rare. A full breakdown of the fade-percentage mechanic is in a separate guide.
The finish isn't limited to knives: it also shows up on several guns (AWP, Glock-18, M4A1-S, MAC-10, MP7, R8 Revolver, UMP-45) and on one glove model. Knife Fade has a StatTrak version but no Souvenir version. For gun Fade, whether StatTrak or Souvenir exists depends on the specific skin and where it's sourced from — there's no single rule. ★ Karambit | Fade is one of the most recognizable examples: from $1,890 in Factory New to $2,000 in Minimal Wear, with the StatTrak version running around $1,830.
Doppler: Phases and Gems
Unlike Fade, Doppler doesn't run on a continuous scale: a copy's look comes from one of seven fixed variants — four phases, Phase 1 through Phase 4, which trade much closer to each other in price than to the gems, plus three far rarer gems: Ruby, Sapphire, and Black Pearl. Regular Doppler and Gamma Doppler are two related but separate lineups: regular Doppler's gems are Ruby, Sapphire, and Black Pearl, while Gamma Doppler has a single gem, Emerald, and the gem sets don't overlap between the two lineups; more detail is in a separate guide to Gamma Doppler phases. Both Doppler variants only exist on knives — neither ever appears on guns or gloves.
The price gap between phases and gems is enormous. On the ★ Karambit, ordinary phases run from about $1,310 to $1,890 in Factory New, while the gems cost an order of magnitude more: Sapphire around $5,010, Ruby around $8,130, Black Pearl around $8,630. Which of the top two gems ends up pricier, Ruby or Black Pearl, depends on the specific knife model and current demand: on the ★ M9 Bayonet at the time of writing, Ruby ($8,300) edges out Black Pearl ($8,040), while on the Karambit and Butterfly Knife the order flips. Either way, the gems are a different, far more expensive league than the ordinary phases.
Doppler Gems: The Priciest Part of the Finish
On the ★ Butterfly Knife, the spread between phases and gems is even more dramatic: ordinary phases run from $2,090 to $4,430 in Factory New, while the gems go well past that range — Sapphire around $6,710, Ruby around $10,940, and ★ Butterfly Knife | Doppler Black Pearl sits around $17,000. That makes Black Pearl on the top-tier knife models one of the most expensive non-unique skins in the game. Gems are considerably rarer than ordinary Doppler phases, and Black Pearl in particular is one of the rarest variants — it's the combination of low odds, demand, and the specific knife model that explains the massive premium over ordinary phases.
Which Knives Carry Both Finishes
Fade and Doppler overlap on most premium knife models: ★ Karambit, ★ M9 Bayonet, ★ Butterfly Knife, ★ Bayonet, ★ Falchion Knife, ★ Flip Knife, ★ Gut Knife, ★ Huntsman Knife, ★ Navaja Knife, ★ Nomad Knife, ★ Shadow Daggers, ★ Skeleton Knife, ★ Stiletto Knife, ★ Survival Knife, ★ Talon Knife, and ★ Bowie Knife. A couple of exceptions: the Classic Knife and the Kukri Knife have Fade but no Doppler, so the choice isn't actually doubled on every model.
Both finishes are cheapest not on the "premium" models but on compact ones like the Navaja, the Gut Knife, and the Shadow Daggers: for example, ★ Navaja Knife | Fade starts around $100, and ordinary Doppler phases on that model start around $105. The ★ M9 Bayonet costs noticeably more — Fade from $940 — but it's still cheaper than the ★ Karambit and the Butterfly Knife, which hold the title of priciest model for almost any finish, these two included.
Getting a Knife with Fade or Doppler
Both finishes drop from the cases belonging to whichever collection carries that knife model, so which cases you need depends on which knife you're after and which finish that collection even includes. Some models are only available in a handful of older collections, so for rarer knife-and-finish combinations it's simpler to just buy directly on the market than to bank on a specific drop — as with ★ M9 Bayonet | Fade.
The second route is a trade-up contract: five regular Covert-rarity skins can be exchanged for one regular knife or pair of gloves from one of the pools tied to the skins used. The skins don't have to come from the same collection, but which collections you feed in affects the possible outcomes. Using five StatTrak Covert skins instead yields a StatTrak knife — gloves can't come out of it that way, since a StatTrak version of gloves doesn't exist. The contract doesn't let you pick the finish in advance: if you want specifically Fade or specifically Doppler on a given knife, the craft's outcome is still a lottery across the pool of possible knives, not a guarantee of a particular finish.
What Determines Fade and Doppler Prices
Knife model. The Karambit and Butterfly Knife usually cost noticeably more than many other models on the same finish — the base price comes from the model, not the finish.
Fade percentage. This is the main factor within one knife for Fade: as a rule, the higher the fade percentage on a given copy, the higher the collector demand, though the exact premium depends on the knife model and the market.
Phase or gem. For Doppler, fade percentage's role is played by the choice between four phases, which trade much closer to each other than to the gems (Ruby, Sapphire, Black Pearl, Emerald on Gamma Doppler) — the gap between an ordinary phase and a gem can run 5 to 10 times.
Condition. The knife versions of both finishes only exist in Factory New and Minimal Wear. Because of the float range from 0.00 to 0.08, the vast majority of supply lands in Factory New, while Minimal Wear is considerably rarer — so its market price can sometimes come out surprisingly high due to low liquidity and few listings, not because wear itself makes the knife more valuable.
StatTrak and Souvenir. Knife Fade and Doppler both have StatTrak versions that usually cost more than the regular ones, and neither finish has a Souvenir version on knives. For gun Fade, whether StatTrak or Souvenir exists depends on the specific skin.
Fade vs Doppler: Which to Choose
The table compares the finishes themselves on key traits, not specific skins against each other — a direct price comparison only makes sense on the same knife model:
| Trait | Fade | Doppler |
|---|---|---|
| What sets the price | That copy's fade percentage (pattern index) | Choice of phase (1 through 4) or gem (Ruby / Sapphire / Black Pearl / Emerald on Gamma Doppler) |
| Price spread within the finish | Tied to coverage percentage, premium varies by model and market | Sharp: gems cost 5x or more than ordinary phases |
| Where it appears | Knives, some guns, one glove model | Knives only |
| StatTrak | Exists on knives; depends on the specific skin for guns | Exists, usually pricier than the regular version |
| Souvenir | Doesn't exist on knives; depends on the specific skin for guns | Doesn't exist |
| Conditions | Knives: FN and MW only (wider range on guns and gloves) | FN and MW only |
| Best for | Buyers who want a predictable, smooth gradient and room to find a better pattern within budget | Buyers willing to gamble on a gem for top-tier status, or happy with a predictable ordinary-phase price |
Frequently Asked Questions
Which is more expensive, Fade or Doppler?
Depends what you're comparing. An ordinary Doppler phase on a given knife usually costs about the same as, or a bit less than, Fade on that same knife, but a Doppler gem (especially Ruby or Black Pearl) costs several times more than any Fade copy on that model — the priciest sales in general come from Doppler gems, not top-percentage Fade patterns.
Which knives carry both finishes?
Most premium models — the Karambit, M9 Bayonet, Butterfly Knife, Bayonet, Falchion Knife, and others. The exception is the Classic Knife and the Kukri Knife: both have Fade but no Doppler.
Is it worth paying extra for a Doppler gem?
If the goal is status and recognizability, a gem justifies the premium: Ruby, Sapphire, and Black Pearl read instantly in-game and cost several times more than ordinary phases precisely because of how rarely they drop. If putting money in predictably, without a lottery on looks, matters more, an ordinary Doppler phase or a Fade with a solid percentage gets you the same knife for a lot less.
Can you get Fade or Doppler in a low float?
Technically yes, but the choice is limited: the knife versions of both finishes have a float range from 0 to 0.08, meaning only Factory New and Minimal Wear exist. More worn versions of these finishes simply don't exist, so looking for a Battle-Scarred copy is pointless.
