Five-SeveN Case Hardened Blue Gem: Explained
In Counter-Strike 2, few skin types hold the same mythical status as the Case Hardened Blue Gem. These highly sought-after skins are distinguished by their blue-tinted finish, which appears due to a rare Case Hardened pattern generated when the skin is unboxed. While most Case Hardened skins showcase a mix of purple, gold, and blue, only a small percentage are predominantly blue — these are what collectors and traders call Blue Gems.
The Five-SeveN Case Hardened has become a hidden gem in this category with its own Case Hardened variant. It might not get as much spotlight as knives or AK-47s, but Five-SeveN Blue Gems are becoming a prized item for seasoned skin investors.
Case Hardened Pattern: Explained
Not all Blue Gems are created equal. The rarity and value are largely determined by the pattern index — a number between 0 and 999 assigned to each skin upon unboxing. Based on community consensus and market demand, these patterns are ranked into tiers. Here’s what each tier represents:
Case Hardened Blue Gem Tier | Pattern Index |
---|---|
Tier 1 | 189, 363, 532, 648, 689, 872 |
Tier 2 | 25, 151, 177, 215, 321, 631, 670, 700, 724, 875, 879, 888 |
Tier 3 | 13, 28, 101, 103, 126, 265, 344, 369, 381, 387, 413, 426, 428, 430, 434, 450, 468, 555, 557, 627, 661, 768, 770, 791, 809, 823, 844, 849, 874, 905, 927, 935, 955, 969, 979 |
Tier 4 | 72, 81, 87, 112, 122, 125, 168, 174, 179, 187, 273, 305, 310, 447, 497, 512, 525, 571, 592, 640, 685, 760, 828, 833, 843, 862, 878, 887, 951, 985 |
Gold Gem | 22, 33, 41, 52, 156, 158, 164, 167, 192, 195, 219, 308, 324, 393, 427, 451, 486, 524, 559, 608, 653, 686, 691, 744, 747, 825, 867, 929, 931, 972, 981 |
Tier 1: The Crown Jewels

Pattern Indexes: 189, 363, 532, 648, 689, 872
Tier 1 patterns are the most saturated with blue, often covering almost the entire slide of the Five-SeveN. These skins are extremely rare and command the highest prices on the market. A Tier 1 Five-SeveN Blue Gem is considered the holy grail — collectors will often pay massive premiums
Tier 2: Strong Blue Presence

Pattern Indexes: 25, 151, 177, 215, 321, 631, 670, 700, 724, 875, 879, 888
Tier 2 skins still display a significant amount of blue, but with some areas showing signs of gold or purple hues. These are highly valuable, especially if the blue appears prominently on the main visible portion of the gun. While not quite as legendary as Tier 1, they’re still among the most admired.
Tier 3: Partial Blue Appeal

Pattern Indexes: 13, 28, 101, 103, 126, 265, 344, 369, 381, 387, 413, 426, 428, 430, 434, 450, 468, 555, 557, 627, 661, 768, 770, 791, 809, 823, 844, 849, 874, 905, 927, 935, 955, 969, 979
These patterns feature patches or streaks of clean blue, but not enough to dominate the entire skin. They often look more mixed or marbled with other colors. Tier 3 patterns may still fetch decent prices, especially from buyers who want a “budget” Blue Gem look, or those aiming for uniqueness without chasing the top tiers.
Tier 4: Hints of clean Blue

Pattern Indexes: 72, 81, 87, 112, 122, 125, 168, 174, 179, 187, 273, 305, 310, 447, 497, 512, 525, 571, 592, 640, 685, 760, 828, 833, 843, 862, 878, 887, 951, 985
Tier 4 patterns contain small amounts of clean light blue, perhaps just at the tip or around the edges. They may appeal to casual fans or traders looking to hold onto a minor Blue Gem at a lower cost. While these don’t carry the prestige of higher tiers, they’re still noteworthy within the Case Hardened ecosystem.
Gold Gem: The Counterpart

Pattern Indexes: 22, 33, 41, 52, 156, 158, 164, 167, 192, 195, 219, 308, 324, 393, 427, 451, 486, 524, 559, 608, 653, 686, 691, 744, 747, 825, 867, 929, 931, 972, 981
Interestingly, while Blue Gems steal the spotlight, there’s a counterpart fanbase for Gold Gems — skins with a prominent gold/yellow sheen. These patterns are also cataloged and collected, and although they don’t command Blue Gem prices, they hold aesthetic and niche value.
