There are many rare skins in CS2, but the M9 Bayonet Emerald is something completely different. The first time I saw this knife in the game, I was inspecting it in a perfect light and shadow. At that moment, I was shocked. The M9 has a sharp shape, and with a layer of high-gloss emerald green paint, it is like a glowing gem – it is not an ordinary knife skin, but more like a symbol of status.
What is special about it? The extremely low drop rate, the nearly mirror-like green luster, and the fact that it is not only a type of Doppler series, but also recognized as the “top Doppler”. If you are not only looking for rarity, but also the top of the skin circle, then this is the answer.
In this article, I will talk about everything I know about this knife in detail, from its origin, price, float value to different pattern distribution. Whether you are planning to buy one or just want to know why this knife is so popular, I hope these contents can help you.
What Is the M9 Bayonet Emerald? Rarity, Doppler Phases, and Origins
If you’re just getting into CS2 skins, you might be wondering what the term “Emerald” even means in this context. Technically, the M9 Bayonet Emerald is a Doppler Phase variant, but it’s not like Phase 1 or 2. It’s a rare gemstone-tier drop that only comes in Factory New condition, exclusively from the Gamma Case family.
Let’s rewind a bit. The Doppler knives come in various phases:
Phase 1 through 4 (mostly black-pink, purple, or blue-green variants)
Ruby (deep red)
Sapphire (bold blue)
Black Pearl (a swirl of purple-black)
Emerald (vibrant green and the rarest among Gamma Dopplers)
What sets the Emerald apart? It only appears on Gamma Doppler finishes, which you can only unbox from:
Unlike rubies or sapphires, Emerald can only be found in the Gamma series, and is a rare treasure unique to this series. This also makes its production extremely low, but the demand among players is extremely high, and it is destined to be a dream knife that is in short supply.
In terms of appearance, the M9 Emerald does not have complex patterns or dazzling light and shadow like some Doppler versions. It is more like a whole piece of emerald green gemstone polished into a blade, with a clean and smooth metallic luster. There is no extra decoration, but it looks more advanced and more oppressive because of its simplicity. This low-key luxury is the real charm of the M9 Emerald.
Price Guide: What an Emerald M9 Bayonet Costs in 2025
Let’s talk about the number that scares (and excites) most players—price. As of mid-2025, the Factory New M9 Bayonet Emerald hovers in a $4,000–$6,000 range depending on market trends, float value, and StatTrak status. And that’s without pattern-specific premiums.
Here’s a detailed breakdown:
| Variant | Float Range | Price (USD) |
| Factory New (Regular) | 0.00–0.08 | $4,000–$5,000 |
| Factory New + Clean Pattern | 0.01–0.03 | $5,200–$5,800 |

The price fluctuates based on:
Float value (the lower, the better)
Pattern cleanliness (no visible scratches or blemishes)
StatTrak availability (rarer and more desirable)
Market platform (Steam or third-party sites like GOCSGO)
If you’re trading for one, be prepared to offer a mix of high-tier knives, gloves, or premium AWP/AK skins. This knife isn’t something players part with easily.
How to Get an M9 Bayonet Emerald: Drops, Cases, and Market Tips
If you’re hoping to unbox an Emerald M9 Bayonet yourself, let me be blunt—it’s going to be a long shot. The Emerald is only available through Gamma and Gamma 2 cases, and it has an ultra-rare chance of dropping. Even if you do hit the Doppler tier, there’s no guarantee you’ll get the Emerald variant.
Here are your main options:
Open Gamma Cases
You’ll need:
A Gamma Case or Gamma 2 Case
A key (purchased separately)
A whole lot of luck
The chance of getting a knife is already very low, only about 0.26%, and in this extremely small chance, it is even more difficult to get an M9 Emerald. But even though they know it is almost impossible, there are still many players who are willing to take a chance – the feeling of accelerated heartbeat and full concentration when opening the box is the reason for their enthusiasm.
Buy It Directly
This is the most straightforward method. Visit:
Steam Market (usually more expensive due to fees)
Buff163 (popular for lower prices and trusted in the trading community)
Make sure the listing is legit—check float, inspect the skin, and ask for a history if you’re spending big.
Trade for One
Trading can sometimes yield better value than buying outright. Post on Reddit or use CS2 trading Discords. Just be patient—it might take time to find a willing seller.
Float, Patterns, and What Impacts Emerald’s True Value
Not all Emerald M9 Bayonets are created equal. Two knives can have the same finish but wildly different values based on float and pattern quality.
Float Value
Float is a number between 0 and 1 that determines how “worn” a skin appears. For Emerald M9 Bayonets:
Only Factory New floats (0.00–0.08) exist
The sweet spot is 0.01 or lower for maximum visual clarity
Ultra-low floats (like 0.000X) add collector value
A knife with a 0.005 float and minimal surface blemishes will always be priced higher than one at 0.07 with scratches.
Pattern Index
Emeralds don’t have multiple “phases,” but they do have pattern indexes. These determine how the green gradient sits on the blade. Some patterns are:
Super clean: nearly full coverage with no black streaks
Spotty or faded: black/grey interruptions on the blade
While most buyers won’t pay extra for a specific pattern, high-end collectors often will. The cleanest Emeralds (sometimes dubbed “Perfect Emeralds”) command the highest premiums.
Pattern Tips
Before buying:
Use a CS2 inspect tool or inspect link
Look for symmetry, full-color coverage, and lack of imperfections
Compare with other screenshots or float databases
Trust me, a few minutes of research can save you thousands—or make you thousands—depending on which side of the trade you’re on.
