AK-47 Case Hardened Blue Gem Patterns
Many Counter-Strike players can agree that the AK-47 is hands-down the most iconic weapon in the game, so it’s vital for every serious player to have a good skin for it. There are a bunch of different AK-47 skins, but the AK-47 Case Hardened is considered as one of the most legendary ones.
Its prestige mainly comes from the Blue Gem patterns, which can skyrocket its price by over 100 times, especially the iconic number one pattern – #661.
In this AK-47 Blue Gem guide, we’ll tell you everything you need to know, from what it is and which patterns are objectively best.
What Is the AK-47 Case Hardened?
The AK-47 Case Hardened is a Counter-Strike weapon skin released all the way back in 2013. It is one of the first skins released in the game, which is what partly makes it such a legendary skin.
The AK-47 Case Hardened can only be found in the original CS:GO Weapon Case, which is one of the most expensive weapon cases in the game. So, the starting price for a regular Case Hardened AK-47 is already pretty high.
Like every other Case Hardened skin in the game, this AK-47 is mainly made up of three colors, which include blue, gold, and purple. However, the Case Hardened AK-47 has 1,000 different patterns, with each altering its look.
These patterns play a very important role in the AK-47 Case Hardened skin’s appearance and price point, so it’s very important to understand what that means and how it works before buying one. That’s exactly what we’ll talk about in this Case Hardened AK-47 guide, so make sure to stick around!
What Is an AK-47 Case Hardened Blue Gem?
Earlier, we mentioned that there are 1,000 different AK-47 Case Hardened patterns. The key takeaway here is that some patterns are considered rarer than others.
Your typical Case Hardened AK-47 will feature a combination of blue, gold, and purple colors. However, there are some very rare patterns that cause the skin to display abnormal amounts of blue colors instead of a balanced mix of all three. Since these patterns populate the skin with blue, we call them CS2 (CS:GO) Blue Gem Patterns.
To determine whether an AK-47 Case Hardened pattern is a Blue Gem one, we’re mainly looking at the amount of blue coverage on its playside. If there’s way more blue on the skin compared to gold and purple, there’s a good chance you’re looking at a Blue Gem Case hardened AK-47 pattern.
Blue Gem patterns are not just rare – the community also believes they look much better than the regular, bland patterns. That’s exactly why collectors are always ready to pay huge premiums for these bad boys.
How AK-47 Case Hardened Patterns Work?
We’ve gotten an introduction to what AK-47 Case Hardened patterns are, but to fully understand the concept, you also need to know how they work.
First, you need to know that every Counter-Strike skin is assigned to a pattern index right after you unbox it from a weapon case or receive it from a drop. This pattern index is a random number between 0 to 999, so we’re looking at 1,000 different patterns. This pattern cannot change – once it’s assigned to a skin, it will stay that way forever.
Now, the Case Hardened skin is a pattern-based skin. There is this huge canvas where all of its blue, gold, and purple textures are painted – just like a map. So, every single pattern index is just the game dropping the AK-47 on different parts of that canvas. Then, the skin is going to absorb those colors – and that’s how the skin will end up as.
Since the AK-47 is being plopped onto different spots on the canvas, you’ll quickly notice that AK-47 Case Hardened skins tend to look different from each other – no pattern looks the same. In rare cases, the AK-47 ends up on a blue-populated area, which is exactly how a pattern ends up as a Blue Gem.
It’s worth noting that skins with the same pattern index will always look the same. For example, your Case Hardened AK-47 skin with a pattern number of #661 will always look exactly the same as another guy’s #661 pattern.
How AK-47 Blue Gem Patterns Are Ranked
There are close to 150 AK-47 Case Hardened pattern seeds that qualify as a Blue Gem pattern. However, not all of them are ranked equally.
To differentiate the Blue Gem patterns, the community has come up with a ranking system, dividing all the AK-47 Blue Gem patterns into four tiers – Tier 1 being the best of the best, while Tier 4 patterns are mediocre.
There are several factors that affect an AK-47 Blue Gem’s pattern ranking, and some of the main ones include:
- Playside blue percentage
- Receiver blue coverage
- Symmetry
- Minimal gold coverage
- Backside appearance
But don’t worry – you don’t need to rank any AK-47 Case Hardened Blue Gems yourself, as the community has already done it for you. We’re going to take a look at all the Blue Gem AK-47 patterns and which ranking tiers they fall under.
AK-47 Case Hardened Blue Gem Pattern Tier List
So, now we know what AK-47 Blue Gem patterns are, how they work, and how they are ranked. Let’s actually take a look at the exact pattern seeds that qualify for a Blue Gem pattern.
There are 146 AK-47 Case Hardened patterns that are accepted as Blue Gem patterns. Like we touched on earlier, they are also ranked in tiers, and you can see the complete list below:
| Blue Gem Tier | Pattern Seeds |
| Tier 1 | 661, 151, 955, 321, 387, 670, 179 |
| Tier 2 | 592, 4, 905, 13, 168, 429 |
| Tier 3 | 555, 442, 978, 139, 828, 969, 750, 695, 103, 112, 733, 844, 228, 868, 434, 698, 74, 996, 760, 375, 708, 823, 690, 791, 278, 917, 463, 711, 849, 92, 82, 450, 512, 310, 713, 11, 721, 236, 172, 950, 147, 782, 322, 363, 189, 961, 497, 430, 887, 426, 862 |
| Tier 4 | 770, 648, 28, 575, 73, 798, 557, 627, 532, 541, 935, 453, 479, 872, 522, 525, 664, 622, 494, 344, 965, 775, 847, 209, 689, 306, 803, 169, 577, 381, 878, 2, 888, 526, 879, 126, 605, 468, 269, 891, 481, 985, 715, 248, 456, 420, 681, 32, 397, 493, 788, 256, 470, 418, 927, 182, 178, 685, 407, 507, 65, 200, 694, 922, 795, 809, 296, 842, 194, 431, 341, 447, 130, 205, 428, 230, 458, 1000, 242, 34, 325, 724 |
Best AK-47 Case Hardened Blue Gem Patterns
The table above tells you every AK-47 Case Hardened Blue Gem pattern, but let’s actually dive into the best ones under each tier:
#661 Pattern — #1 Blue Gem

There’s no question about it: the number one AK-47 Blue Gem pattern is undoubtedly pattern number #661, which is also known as the “Scar Pattern.”
The AK-47 Blue Gem pattern #661 has the highest blue coverage at the top of the skin, with a whopping 76.13%. This pattern also has a visible golden scar near the top, surrounded by an almost completely blue receiver. The Case Hardened AK-47 does not get any better than this.
This AK-47 pattern in StatTrak Factory New condition sold for over a million dollars, making it one of the most expensive CS2 skins ever sold. The Non-StatTrak Factory New ones are also valued at $150,000 to over $200,000, so you’re really looking at life-changing money if you manage to unbox one.
#670 Pattern — Tier 1

It’s safe to assume that pattern #661 is inaccessible for most people due to its absurd price range. But, if you’re looking for a Tier 1 Blue Gem AK-47 that’s a close second, we recommend checking out pattern #670.
Pattern #670 still has a very high blue percentage, sitting at around 70.96%. You’ll see a visible golden scar on the rear part at the top rear, which is this pattern’s only downside. A cool trick is to cover that scar using a sticker.
It’s also worth noting that pattern #670 has a very golden barrel, which could be something collectors like.
#955 Pattern — Tier 1

Similar to all other Tier 1 AK-47 Case Hardened Blue Gem patterns, pattern #955 also has a very high percentage of blue at 72.86%. It has a very clean top side, which is almost completely blue – that’s primarily what collectors are looking for.
Pattern #905 is also unique, as it has an almost completely golden barrel, which is something no other Tier 1 Blue Gem Case hardened AK-47 has. It’s also far more affordable than pattern #661, but we’re still looking at five figures in Factory New condition.
#905 Pattern — Tier 2

Moving down a tier, we’ll take a look at some of the best Tier 2 patterns starting with number #905. The blue percentage sees a very noticeable drop from Tier 1 patterns, as #905 is 58.92% blue.
However, this AK-47 Blue Gem pattern still has a really nice blue top, covering almost the entire area. You will also see lots of blue on the gun barrel, which is definitely something that attracts Blue Gem collectors.
All in all, pattern #905 is easily one of the best Tier 2 AK-47 Blue Gem patterns out there in terms of blue percentage and placement.
Pattern #316 — Tier 3

Pattern #316 is another Tier 3 AK-47 Case Hardened Blue Gem worth checking out. While it doesn’t have the same level of blue coverage as the higher-ranked patterns, it still offers enough blue on the playside to make it appealing to collectors looking for a more affordable Blue Gem.
As a Tier 3 pattern, #316 is a good middle-ground option for buyers who want the distinctive Blue Gem look without paying the premium associated with Tier 1 and Tier 2 patterns. Its overall appearance and pattern placement make it a solid choice for collectors on a mid-range budget.
#363 Pattern — Tier 3

The Tier 3 category of AK-47 Case Hardened Blue Gems is when the blue percentage starts falling below the halfway point.
Pattern #363’s blue percentage is sitting at 42.69%. It has solid blue coverage at the top of the weapon, but its rear features more golden hues than you’d typically want.
However, the AK-47 Blue Gem pattern #363’s unique feature is its golden magazine. It has a very low blue percentage on its magazine at only 1.99%, so you’ll see almost completely gold on the mag except for a single blue dot.
#750 Pattern — Tier 3

The second Tier 3 Case Hardened AK-47 pattern we’ll feature is number #750, which is 51.5% blue on its playside, and that’s still very solid.
Most of the weapon’s top half is blue until you reach the rear, which is almost completely covered in gold. The barrel of the AK-47 Blue Gem pattern #750 is also fully gold, so if you’re into golden barrels, this specific pattern is definitely one to target.
#770 Pattern — Tier 4

Pattern #770 is a Tier 4 pattern worth checking out, and it is 41.45% blue on its playside. However, it has strong blue coverage at the top, making it a very decent Blue Gem option, especially in this tier.
The prices for the AK-47 Case Hardened pattern #770 falls below the $1,000 mark, which is way more affordable than the other patterns we discussed earlier.
Pattern #819 — Tier 4

Pattern #819 falls into the Tier 4 category of AK-47 Case Hardened Blue Gem patterns. Like other patterns in this tier, it offers a more budget-friendly way to get into the Blue Gem market while still retaining the unique blue, gold, and purple finish that makes Case Hardened skins so popular.
It may not have the same collector demand as patterns from the higher tiers, but #819 can still be an attractive option for players who prioritize the Blue Gem appearance over maximum rarity or investment potential.
Pattern #129 — Tier 4

Pattern #129 is another Tier 4 AK-47 Case Hardened Blue Gem pattern that is worth considering for buyers with a smaller budget. While Tier 4 patterns generally command lower premiums than the top-ranked Blue Gems, they can still provide plenty of visual appeal.
For collectors who want a Case Hardened AK-47 with noticeable Blue Gem characteristics without spending the huge sums associated with patterns like #661, #129 offers another affordable option to consider.
Estimated AK-47 Case Hardened Blue Gem Prices by Tier
If you’re still deciding what Blue Gem AK-47 tier to grab, here’s a table that might help you out:
| Tier | Example Pattern Seeds | Approximate Price Range | Premium vs Regular AK | Collector Demand | Typical Buyer |
| Tier 0 (#661 only) | #661 (Scar Pattern) | $150,000 – $1,000,000 | Premium | Wanted, but priced out fast | Trading whales with high net worth |
| Tier 1 | #670, #151 | $3,000 – $35,000 | Premium | Wanted, but priced out fast | High net-worth collectors |
| Tier 2 | #905, #592 | $1,000 – $15,000 | Premium | High demand | Collectors who like hitting the sweet spot |
| Tier 3 | #363, #750 | $800 – $3,000 | Regular | Niche demand | Collectors with mid-range budgets |
| Tier 4 | #770, #648 | $400 – $1,200 | Regular | Low demand | Casual buyers |
Does Float Matter on an AK-47 Blue Gem?
Yes, like every other skin in the game, float values do matter on the AK-47 Case Hardened Blue Gem skin, because collectors naturally want the best of the best.
However, unlike most other CS2 skins, the AK-47 Case Hardened skin doesn’t really get torn as it goes up in float values. Instead, the difference comes down to its shine and rust – high-float AK-47 Blue Gems will look a little darker compared to low-float ones.
So, hardcore collectors will only want their Blue Gem AK-47 skins in either Factory New or Minimal Wear condition. Meanwhile, it’ll be harder to sell CS2 (CS:GO) skins, even Case Hardened patterns, that are in Field-Tested, Well-Worn – or even worse – Battle-Scarred.
Still, though float values are important, it’s worth noting they do not change an AK-47 Case Hardened skin’s pattern. Pattern seeds will still outweigh float values in most cases.
How Rare Is an AK-47 Case Hardened Blue Gem?
The Blue Gem Case Hardened AK-47 skin is hands-down one of the rarest ones in the game.
First of all, it resides in one of the most expensive CS2 cases, which is the original CS:GO Weapon Case. These cases are scarce and will cost you $100 each to open already, which makes people scared to unbox them.
The chances of unboxing an AK-47 Case Hardened from a case is roughly 1.60%, as you have a 3.20% chance to unbox a Classified skin, and there are two of them in the CS:GO Weapon Case.
Once you unbox one, you’ll also have to land one of the rare Blue Gem pattern seeds. Since there are only seven Tier 1 Blue Gem patterns, the odds of getting one is 7 in 1,000, on top of the 1.30% chance of unboxing the skin in the first place.
So, you can imagine how rare it is to get the AK-47 Blue Gem pattern #661, and why collectors are willing to spend hundreds of thousands of dollars on them. The supply for them is just extremely limited, while demand is high.
How to Check an AK-47 Blue Gem Pattern
From what we’ve discussed above, we now understand how important pattern seeds are for the AK-47 Case Hardened skin. So, it’s important that you know how to check AK-47 Case Hardened patterns yourself.
Fortunately, checking an AK-47 Blue Gem pattern seed is pretty easy.
Just follow these steps below:
- Grab the skin’s inspect link, then inspect it in the CS2 client.
- On the inspect menu, look for the “i” icon at the bottom. Then, hover your mouse over it.
- You should see additional information pop up. Here, look for “Pattern Index.”
- The game will display a number between 0 to 999. That number is the pattern seed.
While you’re at it, it’s also worth taking a look at the skin’s float value. You can always compare that number to a float database to determine its condition.
So, if you’re ever hunting for a specific AK-47 skin, make sure to follow these steps and verify whether it is actually an AK-47 Blue Gem pattern.
Where to Buy or Sell an AK-47 Case Hardened Blue Gem
If you’ve decided that you want to buy one for yourself, the next step is figuring out where to buy (CS2) CS:GO skins.
Since we’re working with rare patterns here, we firmly recommend using a third-party marketplace website as opposed to the Steam Market. These trading platforms have built-in plugins that’ll display the AK-47 Case Hardened pattern seed and show you what it looks like.
When you’re planning to buy a Blue Gem Case hardened AK-47 from one of these third-party websites, you should only use trusted marketplace websites, like Skin.Place, for example. Using reputable sites will ensure you don’t get scammed and end up with nothing.
Of course, you should always do your due diligence and double-check the pattern seeds and float values before you close a deal. You should also compare recent sales so you know you’re not getting swindled.
If you’re doing a cash trade, make sure you’re using protection like using a trusted middleman. You’ll be working with up to thousands of dollars, so always tread carefully.
Is an AK Case Hardened Blue Gem a Good Investment?
Yes, the AK-47 Case Hardened Blue Gem can be a good investment, but it really depends.
It’s worth noting that the AK-47 Case Hardened is a very scarce skin since it’s coming from a rare case, so the supply is very limited. The value of these bad boys is going to continue appreciating and the demand doesn’t seem to be dropping.
However, low-tier Blue Gem patterns, like Tier 3 and Tier 4 ones, might not be a strong long-term investment due to low demand. If you want something reliable in the long run, we recommend looking at Tier 2 and Tier 1 Blue Gems especially.
Just remember that the CS2 skin market can be volatile at times, and that no investment is guaranteed.
Conclusion
So, the AK-47 Case Hardened Blue Gem is still one of the most sought-after CS2 skins, even though it’s been in the game for more than a decade. The main reason is its rare Blue Gem patterns, which can multiply the skin’s value tenfold.
The number one pattern – pattern #661 – is the ultimate collector’s item, and is a skin that only belongs to the most expensive CS2 inventories for its absurd price ranges. However, there are many other AK-47 Case Hardened Blue Gem patterns that are more affordable and offer solid collector appeal and investment potential.
Just remember to always verify pattern seeds and only buy these expensive skins on trusted marketplaces.
