CS2 knives are among the most valuable virtual items in all of gaming, with rare patterns and finishes sometimes reaching extraordinary prices. But what is the most expensive CS2 knife in 2026, and how much is it really worth?
From the legendary Karambit Case Hardened Blue Gem #387 to rare Emerald, Sapphire, and Ruby finishes, this guide ranks the most expensive CS2 knives and explains what makes them so valuable.
We’ll also separate verified market prices from private offers and collector estimates.
What Is the Most Expensive Knife in CS2?
The most expensive knife in CS2 is widely considered to be the Karambit Case Hardened Blue Gem #387 in Factory New condition. Its value is commonly estimated at around $1.5 million or more, with some collector estimates reaching $2 million.
However, it is important to clarify that this is not a verified $1.5 million public sale. The figure comes from reported private offers and collector valuations. The owner reportedly rejected an offer of approximately €1.2 million in 2021.

The examples presented below should be treated as a snapshot rather than a permanent leaderboard. Prices move constantly, while exceptional patterns can sell privately for substantially more than ordinary listings.
Here are some of the most expensive CS2 Knife skins at the moment:
| 1 | Karambit Case Hardened Blue Gem #387 | Factory New | $1M+ | Collector estimate / reported offer |

| 8 | Skeleton Knife Crimson Web | Factory New StatTrak | ~$17,000 | Market listing |
Karambit Case Hardened Blue Gem #387
This is the undisputed collector trophy. Pattern #387 has an exceptionally high concentration of blue on the play side, while the Factory New example has an unusually desirable float.
Its seven-figure valuation is driven by extreme rarity, collector demand and the fact that there is no established public-market price for the exact knife.
Karambit Gamma Doppler Emerald
The Emerald version of the Gamma Doppler is one of the most desirable Karambit finishes.
Factory New examples command a major premium because Emerald is the rarest Gamma Doppler phase and the Karambit itself is among the most sought-after knife models. Current market data places high-quality examples in the five-figure range.
M9 Bayonet Gamma Doppler Emerald
The M9 Bayonet combines a large blade with the distinctive Emerald finish. This is an exquisite CS2 knife skin that goes well with just about any pair of gloves.
Butterfly Knife Doppler Sapphire
The Butterfly Knife’s animation and popularity make Sapphire examples particularly desirable. Factory New Sapphire knives can command several thousand dollars, with exceptional floats and favorable market conditions pushing prices higher.
Butterfly Knife Gamma Doppler Emerald
Emerald Butterfly Knives are another elite-tier collectible. If you own this expensive CS2 skin, you can either sell it for a lot of money or keep it as a testament to your dedication to the game.
M9 Bayonet Doppler Ruby
Ruby is one of the premium Doppler phases, recognizable by its predominantly deep-red appearance. Factory New M9 Bayonet Rubies typically trade in the high-thousands, with float, liquidity and seller reputation affecting the final price.
Karambit Doppler Ruby
A Ruby Karambit combines an extremely popular knife model with one of Doppler’s most desirable phases. It remains a major collector piece, particularly when the float is exceptionally low.
Skeleton Knife Crimson Web
Crimson Web Skeleton Knives illustrate how condition and StatTrak can dramatically change value. Standard Factory New examples are currently around $1,200, while rare StatTrak Factory New examples can list for more than $17,000.

Browse CS2 KnivesWhat Makes a CS2 Knife So Expensive?
Several factors determine whether a knife is merely expensive or genuinely collectible:
If you’re interested in how to get a knife in CS2, there are multiple viable methods. But expensive CS2 knife skins are typically relatively hard to obtain.
How to Check the Current Price of an Expensive CS2 Knife
Start by identifying the exact knife, finish, pattern seed, float and StatTrak status. Never compare a generic Karambit Gamma Doppler with an Emerald or an exceptional-float example and assume they have the same value.
Normal marketplace listings provide useful benchmarks, but private high-end deals are different.
An owner may ask substantially more for an exceptionally rare item, while a private buyer may negotiate below the asking price.
The #387 Blue Gem Karambit is the clearest example: its million-dollar figure is based on reported offers and collector estimates rather than a verified public transaction.
FAQs
Has the $1.5 million Karambit Blue Gem actually been sold?
No. The often-quoted $1.5 million+ valuation for the Karambit Case Hardened Blue Gem #387 is not a verified public sale. The figure is based on reported private offers and collector estimates. It should therefore be described as an estimated or reported value rather than a confirmed transaction price.
What is the most expensive Butterfly Knife in CS2?
The Butterfly Knife Gamma Doppler Emerald and Butterfly Knife Doppler Sapphire are among the most expensive Butterfly Knife finishes. Exact prices depend heavily on float, marketplace liquidity and current collector demand, so the most expensive available example can change over time.
What is the most expensive Karambit in CS2?
The Karambit Case Hardened Blue Gem #387 is generally regarded as the most expensive Karambit and the most expensive knife overall. Its extraordinary blue pattern and rarity have resulted in reported offers and collector valuations reaching well into seven figures.
Which Doppler phase is the most expensive?
For standard Doppler knives, Sapphire, Ruby and Emerald are among the most valuable phases. The exact order depends on the knife model and market conditions. Emerald is particularly desirable on models such as the Karambit and M9 Bayonet, while Sapphire and Ruby can command exceptional prices on other popular knives.
Why can two copies of the same CS2 knife have very different prices?
The skin name alone does not determine its value. Two identical knives can have different pattern seeds, float values, wear conditions, StatTrak status or other collectible characteristics. For Case Hardened knives, pattern placement can be especially important. An exceptionally desirable pattern can make one copy worth several times more than an ordinary example.
Did the 2025 Trade Up Contract update make knives cheaper?
The 2025 Trade Up Contract changes increased the supply of some high-tier items by allowing certain trade-up combinations to produce knives and gloves. This affected prices across parts of the CS2 market, particularly when additional supply entered circulation. However, the effect was not uniform: extremely rare patterns, exceptional floats and established collector pieces can retain substantial premiums.
What is the most expensive CS2 knife with a verified public sale?
The answer depends on what is considered sufficiently documented as a public transaction. Unlike normal marketplace sales, many of the highest-value CS2 knives change hands through private deals, where prices are difficult to independently verify. For that reason, the $1.5 million+ Karambit Blue Gem figure should not be presented as the highest verified sale. A verified public sale must have reliable evidence of the actual transaction price rather than an asking price, private offer or collector estimate.
