About Blue Gem patterns

Case Hardened normally mixes yellow and blue across the slide; a Blue Gem is the seed where blue takes over and the yellow nearly disappears. The Five-SeveN was one of the first guns to get the finish, so its Blue Gems are long-tracked by collectors.

There is no single definitive Blue Gem Five-SeveN — Tier 1 is a cluster of near-equal seeds (#278, #670, #690, #363, #768, #868). We lead the ranking with #278.

01T1Tier 1 — Best patterns

No example yet
A render will appear when a listing becomes available.
What makes a T1

The best patterns in this skin. Tightest symmetry, deepest coverage, and the visual hallmarks that separate top-shelf examples from everything else.

02T2Tier 2

What makes a T2

Very strong patterns — close to T1 quality but with one or two visual compromises (off-axis tip, slightly less coverage, or a less symmetric back).

03T3Tier 3

What makes a T3

Above-average patterns. Recognisable as "good" but with a clear weakness compared to T1/T2 — useful for buyers who want a hint of pattern premium without paying T1 prices.

04T4Tier 4

A render will appear when a listing becomes available.
What makes a T4

The lower end of curated patterns. Still better than a random unranked roll, but the visual differentiator is subtle.

Everything else — Unranked

The remaining ~915 paint_seeds fall outside the curated tiers. They make up the bulk of Phase 1 supply on every marketplace and don’t carry a pattern premium — what you see is what you get, like the baseline reference (seed #503) we used at the top of this guide. If a seed isn’t listed in T1–T4 or BTA above, treat it as Unranked.
