AK-47 Case Hardened Blue Gem Tier List (2026)
Most AK-47 Case Hardened skins are $40 mud-gold rifles. A handful are five-figure collector anchors, and one — the 661 — traded for over a million when it wore the right stickers. The only difference is the pattern seed. This is the seed-by-seed tier list you reference before you pay case-hardened money, because "blue gem" on a listing title means nothing until the seed backs it up. The Case Hardened blue gem explained guide covers how seeds and tiers work; this page is the tier list itself. The full pattern mechanics live in the patterns, floats and wear pillar.
How the tiers work
The community rates AK-47 Case Hardened seeds by how much blue sits on the playside — the side you see when the rifle is equipped, with the magazine facing left. The more uninterrupted blue, the higher the tier. The blue gem phrase itself isn't a Valve label: it's shorthand for "this seed is blue enough that collectors will pay a real premium." The tiers below reflect the consensus as of mid-2026 from pattern databases, collector forums and recent sales. Seed rankings can shift slightly as new data surfaces, but the top seeds — especially the 661 — are locked in.
The full list of AK-47 Case Hardened seeds runs to one thousand possible patterns. This tier list focuses on the named ones you'll actually encounter in listings and trading conversations.
Tier S — The crown jewels
These are the grails. You will very rarely see any of them listed publicly, and when they trade it's in private collector channels or high-end marketplaces.
| Seed | Blue coverage | Why it's tier S | Typical ballpark (FT+, mid-2026) |
|---|---|---|---|
| 661 | ~90% playside, near-full blue, minimal gold | The most blue on the playside of any AK-47 CH. The 661 FN with four iBP Holo Kato 14s is the most expensive single skin CS2 has ever seen. | Five to seven figures |
| 670 | ~85% playside, heavy blue, small gold patch near the magazine | The second-most-recognised playside gem. Often called "the poor man's 661," which is a rich joke for a five-figure rifle. | Low five figures |
| 387 | ~80% playside blue, centred, tight | Clean, even coverage with less gold splash than 670; some collectors prefer it to 670 for the cleaner layout. | Four figures |
These three seeds have their own orbit. A 661 Field-Tested will outsell a 670 Factory New every time, and even a battered 661 World War Z would start deep in five figures. If you're buying anything in this tier, you already know the buyer pool — and you're verifying the seed from the inspect link yourself before a dollar moves.
Tier 1 — Heavy blue, liquid market
These seeds are genuine full blue-gem territory, but they're findable. You'll see them listed on Buff163 and in collector channels, and they're the top of the tradeable market rather than the museum pieces.
| Seed | Blue coverage | Notes | Typical ballpark (FT, mid-2026) |
|---|---|---|---|
| 555 | ~75% playside, wide blue swath | One of the cleanest T1 seeds; blue sits like a blanket without a lot of gold breakup | $8,000–$15,000+ |
| 321 | ~70% playside, blue concentrated on the upper body | The "blue top" pattern — upper receiver reads almost full blue, lower half has some gold | $5,000–$12,000 |
| 151 | ~70% playside, thick blue band | Chunky blue, slightly uneven but undeniably a gem | $5,000–$10,000 |
| 179 | ~65% playside, consistent | Steady, even blue; less famous than 555/321 but genuine tier 1 | $5,000–$8,000 |
| 955 | ~65% playside, blue with gold stripes | The "tiger blue" pattern — gold streaks cut through the blue, which splits opinion but the coverage is real | $4,000–$8,000 |
Tier 1 seeds are the tier where float actually starts to matter alongside the seed. A Factory New 555 versus a Well-Worn 555 can be a 30–40% gap. Buy the seed first, then let the float decide where in the tier you land.
Tier 2 — Strong blue, accessible
You can own a tier 2 AK for the price of a decent knife. These seeds show unmistakably more blue than a generic copy, they read as a gem to anyone who knows the finish, and they're what most people mean when they say "I own a blue gem AK."
| Seed | Blue coverage | Notes | Typical ballpark (FT, mid-2026) |
|---|---|---|---|
| 592 | ~50% playside, large blue patch on the rear | Blue chunk sits on the stock/rear body area; front half is gold-dominant | $2,000–$4,000 |
| 168 | ~45% playside, blue on the magazine and upper receiver | Recognisable, consistent pattern — the most-traded T2 seed | $1,500–$3,000 |
| 463 | ~45% playside, blue stripe down the centre | A clean blue ribbon through the middle; not a full gem but reads blue on the playside | $1,200–$2,500 |
| 828 | ~40% playside, scattered blue | Less concentrated than the others in T2 but still clearly above generic | $1,000–$2,000 |
Tier 2 is the practical sweet spot. You get a seed that actually registers as a blue gem in a server, and you're spending high-three or low-four figures instead of a car. The caveat: at this tier the float starts competing with the seed — a Factory New 168 might push into low T1 pricing, while a Battle-Scarred one could dip below $1,000.
Tier 3 — Noticeable blue, budget entry
These seeds won't be the star of a collector's showcase, but they're visibly better than the gold-and-grey generics that flood the market. They trade in the hundreds, not thousands, and they're the entry door to "my AK has blue."
| Seed range | What you get | Typical ballpark (FT, mid-2026) |
|---|---|---|
| Dozens of seeds (228, 470, 809, 905, etc.) | A visible blue patch — maybe 20–35% of the playside — not a gem, but clearly not generic | $150–$800 |
This tier is where you stop paying for "blue gem" and start paying for "I like this one." The value is in the look you personally prefer, not in a seed ranking. Check the in-game preview, buy what you like, and don't expect to flip it to a collector.
Generic seeds — the rest
Everything else — roughly 80–85% of all seeds — falls into the generic camp. Mostly gold and grey with a streak or patch of blue. These are $30–$80 rifles that happen to be Case Hardened. They're perfectly fine rifles and they're the cheapest way to own a red-tier AK, but they're not gems and they never will be.
Don't pay a premium for a "blue gem" listing that's really a generic seed with a lucky angle in the listing photo. The marketplace render is almost always a generic preview — inspect the seed yourself.
Blue on the backside — don't pay for it
Some seeds are gorgeous on the backside and ordinary on the playside. Collectors almost never pay for backside blue, because the playside is what you (and everyone else) see in-game. A seed that's tier 2 on the back and generic on the front is worth generic money.
If a listing advertises "hidden blue gem" or "blue on the back," translate it to "not a playside gem." The only exception is a seed with strong blue on both faces — those do carry a small premium, but it's a fraction of what the playside blue alone commands.
How to verify a seed before buying
The flow is the same for every Case Hardened: get the inspect link, run it through a float-and-pattern inspector, read the pattern index number, and compare it against this tier list. The how to check skin float guide walks through the inspect-link flow with screenshots.
Three rules that save money. Verifying the seed yourself is non-negotiable — a listing title is a claim, not a fact, and the difference between seed 661 and seed 618 (a generic) is five figures. The thumbnail lies — Steam's render shows a generic pattern, not your specific seed. Float matters inside a tier but never across tiers — a Factory New tier 3 will never catch a Field-Tested tier 2 on value, because the tier gap is bigger than the condition gap.
And the counterpoint: if you already own an AK Case Hardened, check the seed. You might be sitting on a tier 2 without knowing it, because the previous seller priced it as generic based on the thumbnail.
FAQ
What's the best AK-47 Case Hardened seed? Seed 661. It shows the most uninterrupted playside blue of any AK-47 Case Hardened — roughly 90% coverage with almost no gold on the face. It's the crown jewel of the finish, and the famous Factory New copy with four iBP Holo Kato 14 stickers is worth well into seven figures. 670 and 387 are the next tier down.
How much is an AK-47 Case Hardened blue gem worth? It depends entirely on the seed and tier. A tier 2 seed (e.g. 592, 168, 463) in Field-Tested runs $1,000–$4,000 in mid-2026. A tier 1 seed (555, 321, 151) runs $5,000–$15,000+. The 661 in anything above World War Z condition is five figures bare, and the stickered grail is seven. A generic seed is $30–$80. Always check the seed before you trust a price.
How do I know if my AK Case Hardened is a blue gem? Read the pattern seed. Right-click your AK-47 Case Hardened in your Steam inventory, copy the inspect link, and paste it into a float-and-pattern inspector. It returns the pattern index number — the seed. Compare that number against this tier list or a community blue-gem ranking. A seed of 661, 670, 387 is tier S; 555, 321, 151, 179, 955 is tier 1; 592, 168, 463, 828 is tier 2. The thumbnail in your inventory won't tell you — only the actual seed does.
Does float matter on an AK Case Hardened blue gem? Yes, but less than the seed — and the order matters. The seed sets the tier (S/1/2/3), and the float fine-tunes the price inside that tier. A tier 2 seed in Factory New is worth more than a tier 2 in Battle-Scarred, but a tier 2 in any condition will always outsell a tier 3 in Factory New. Buy the seed first, then optimise the float if the budget allows.
What's the difference between a tier 1 and tier 2 blue gem AK? Coverage and price. Tier 1 seeds (555, 321, 151, 179, 955) show 65–75% blue on the playside and trade in the $5,000–$15,000+ range. Tier 2 seeds (592, 168, 463, 828) show 40–50% blue and trade in the $1,000–$4,000 range. It's not a subtle gap — a tier 1 reads as mostly blue from across the map; a tier 2 reads as "that AK has a lot of blue" but isn't fully drenched.
Can I get a blue gem AK for under $500? Yes, in tier 3. A dozen or so tier 3 seeds show enough blue to stand out from generic copies without entering the true collector tier, and they trade in the $150–$800 range depending on float. At $500 you're usually looking at a Field-Tested copy of a mid-range tier 3 seed or a high-float entry into the bottom of tier 2. Check the live listings and confirm the seed yourself — at this budget range, mislabelled seeds are common.
