Case Hardened — Blue Gem

The more blue on the play side, the pricier. Top seeds with a blue AK top or Karambit blade go for tens or hundreds of thousands of dollars.

Tiers are the collector community’s judgement, not Valve data.

The shares of blue, purple and gold are measured on renders of every pattern: the playside is the side you see in your hands, the backside is the other one. The higher the blue share on the playside, the rarer and more expensive the item.

Colour-share data comes from the open CSFloat dataset (MIT licence). CSFloat

Questions and answers

How do I find the seed of my skin?

The seed is in the item description in your Steam inventory — the Pattern Template line. You can also paste the inspect link into the checker on the patterns page: it returns the seed, the exact float and the verdict.

Why is this pattern valuable?

On Case Hardened and Heat Treated the texture shifts with the seed, so the blue share on the visible side ranges from almost nothing to a full Blue Gem. We take the blue share from renders of every pattern and rank the seeds: the higher the rank, the rarer and more expensive the item.

Does the seed change the price?

There is no per-seed quote: marketplaces sell a skin by name and wear. A rare pattern trades for a multiple of an ordinary copy, but the price is settled between collectors.
