The CS2 Paracord Knife Case Hardened Blue Gem is one of the rarest knives in the game. The Case Hardened is the skin, but it’s the Blue Gem factor that elevates it above the rest. For those out of the loop, a Blue Gem is a rare pattern of Case Hardened knives that have a ton of blue covering the exterior. For certain patterns, this can have a big impact on the price of a Case Hardened Paracord Knife, with Blue Gems costing a lot more than normal patterns.
Every Paracord Knife Case Hardened dropped is randomly assigned one of 1,000 seed patterns, but only a few are considered Blue Gems, hence the rarity. These have then been seperated by the community into four tiers, based on the amount of blue on each. This guide has all the details on every CS2 Paracord Knife Case Hardened Blue Gem pattern, from the 403 down to the Tier 4 options.
Paracord Knife Case Hardened Blue Gem Tier 0 Pattern: 403

The community typically elevates the Paracord Knife Case Hardened Blue Gem pattern 403 above the rest. It’s better than Tier 1, with the blue covering almost the entire exterior. It’s the best CS2 Paracord Knife Case Hardened Blue Gem pattern, and at the time of writing, only six have ever been unboxed (according to CSFloat’s database).
Paracord Knife Case Hardened Blue Gem Tier 1 Patterns

With the Paracord Knife Case Hardened Blue Gem Tier 1 patterns, you’ll find they are all still pretty much covered entirely in blue. Only the pickiest of collectors will take issue with these knives, although there’s a reason they’re commonly considered not to be on par with the 403.
- Paracord Knife Case Hardened Blue Gem Tier 1 Patterns: 58, 169, 316, 449, 456, 577, 583, 585, 634, 681
Paracord Knife Case Hardened Blue Gem Tier 2 Patterns

Even the average player will start to notice the blemishes on the Paracord Knife Case Hardened Blue Gem Tier 2 patterns, with chunks of yellow starting to take hold. Again, though, these options are still a great choice for those who want a Blue Gem Paracord Knife but don’t want to spend thousands on acquiring one.
- Paracord Knife Case Hardened Blue Gem Tier 2 Patterns: 55, 166, 180, 239, 281, 288, 345, 351, 383, 447, 601, 668, 704, 922
Paracord Knife Case Hardened Blue Gem Tier 3 Patterns

In a way, the Paracord Knife Case Hardened Blue Gem Tier 3 patterns are actually better than the Tier 2 patterns. Why? Because the focus becomes less on the amount of blue, but on how it’s distributed. Yes, there’s less blue on these Tier 3 patterns, but you can also start to look at whether the blue and yellow make any interesting designs by themselves.
- Paracord Knife Case Hardened Blue Gem Tier 3 Patterns: 67, 88, 116, 157, 170, 176, 187, 202, 210, 262, 269, 336, 349, 372, 374, 417, 430, 496, 503, 507, 525, 529, 533, 556, 588, 628, 632, 669, 797, 812, 837, 850, 880, 899, 910, 915, 916, 954, 959
Paracord Knife Case Hardened Blue Gem Tier 4 Patterns

If you’re desperate to own a CS2 Paracord Knife Case Hardened Blue Gem, then the Tier 4 patterns get the job done. They have the absolute least to still qualify as a Blue Gem, but hey, they do count. Make sure to look around all the different Tier 4 patterns, and their appearance can vary massively.
- Paracord Knife Case Hardened Blue Gem Tier 4 Patterns: 3, 10, 14, 59, 84, 91, 95, 103, 107, 108, 115, 138, 151, 162, 179, 203, 212, 222, 227, 235, 286, 292, 294, 298, 299, 311, 315, 325, 387, 393, 400, 429, 442, 462, 501, 502, 504, 516, 519, 523, 528, 537, 546, 547, 551, 600, 606, 610, 613, 619, 624, 640, 675, 680, 689, 693, 698, 700, 715, 719, 740, 750, 794, 805, 806, 807, 818, 820, 821, 828, 859, 866, 867, 872, 879, 902, 923, 941, 955, 956, 995

How much does a Paracord Knife Case Hardened Blue Gem cost?
The Paracord Knife Case Hardened Blue Gem price isn’t simple, as it depends on a lot of factors. Pattern tier obviously matters a lot – for example, the only 403 on sale on CSFloat at the time of writing is selling for $9,999, and that’s Battle-Scarred. However, there are only six perfect pattern Paracord Knife Blue Gems in existence, with only one being Factory New, so that could theoretically sell for a lot more. Comparatively, the Tier 4 700 pattern can be found for around $300, so the pattern is definitely the biggest factor in the price.

How do I know if my Paracord Knife Case Hardened is a Blue Gem?

See if the number matches up to any of the patterns listed above – if they do, your Paracord Knife Case Hardened is a Blue Gem.
How does float value affect Blue Gem Paracord Knives?
Float value affects the price of Blue Gem Paracord Knives, although it’s not as significant a factor as the pattern. Of course, a Battle-Scarred skin is going to be worth less than a Factory New one, so keep this in mind when purchasing a Paracord Knife Blue Gem.
