The inclusion of in-game cosmetics can significantly enhance players' gaming experience. CS2's approach to skins is unique and, in many ways, superior to other games.
When CS2 first introduced skins, they incorporated the concept of wear and patterns, significantly contributing to their success in the market.
The "Case Hardened" skins are trendy among the pattern-based skins. With the correct pattern, these skins can transform a weapon into a stunning oceanic blue or a shiny golden metal. However, acquiring such skins can come with a hefty price tag, reaching tens of thousands or even up to a million dollars.

Weapon Finish Origins
Case hardening is a fascinating process that enhances the steel surface by adding carbon and heating it to create a tough exterior while maintaining a softer interior.
In the world of CS2, the Case Hardened pattern holds a special place as one of the oldest skins since its introduction in the Arms Deal Update.
This unique pattern can be found on the AK-47, Five-SeveN, and nearly every Knife, making it one of the most versatile skins available. Its variability sets it apart, leading to a wide range of trading value and rarity, making it a highly sought-after and valued skin in the game!

Blue Gem is the name for Case Hardened skins with the maximum amount of blue on them.
In CS2, there are 20 different knives, the AK-47, Five-SeveN, and MAC-10 with Case Hardened patterns. Each weapon is viral despite having different strengths.
The Case Hardened finish in CS2 is genuinely a work of art. It starts with a base of elegant gray and then comes to life with vibrant hues of bold blue and hints of mesmerizing purple. These beautiful colors are further complemented by warm, inviting gold touches. The unique pattern created from this sheet is then carefully applied to the weapon skin, resulting in a one-of-a-kind design.
With a thousand variations known as seeds, each assigned a numerical value between 0 and 999, there's boundless creativity and excitement in every design. Among these, the deeply admired Blue Gems, with their rich blue patterns, hold a special place in the hearts of Counter-Strike enthusiasts. The diverse range of patterns ensures that there's something for everyone, and the allure of the Case Hardened finish is undeniable, making it a cherished choice in the gaming community.
Regarding Case Hardened skins, Tier 1 patterns are extra unique. They have the most beautiful blue stain, making them sought after. Because of this, they often sell for way more than the usual market price. The blue stain decreases as you move down the tiers, with Tier 4 patterns having the least. Tier 4 patterns are still astonishing, but they usually go for the average market value. Knowing about these different tiers and their unique value to Case Hardened skins is pretty awesome!

Case-hardened skins are exceptional with their diverse and intriguing patterns. The community appreciates skins with more light blue shades, fondly referring to them as "Blue Gems".

A gem's stunning blueness is defined by the abundance of rich blue hues on its surface. In addition, the wide pattern template gives rise to captivating streaks of gold and purple, resulting in delightful variations, like the striking 75% blue gem.
The Five-SeveN | Case Hardened boasts a one-of-a-kind case-hardened finish with eye-catching pattern diversities. It presents a sleek and vibrant design for players who value a weapon's aesthetic appeal. Moreover, this skin is reasonably priced, making it a fantastic addition to your collection.

But if the Five-SeveN gold gem still interests you, its best pattern is 691.
MAC-10 Case Hardened (Blue Gem)
![](https://cdn.sanity.io/images/dmtcrhxp/production/97ee4139d537e27a3b7ae7468391fa6103ce505a-1920x1660.webp?q=30&auto=format)

Steam Price: $9.01 - $78.93
The Mac-10 is the least popular weapon with the Case-Hardened finish. The gun model has three different parts, while the skin only covers one, making getting a full blue gem impossible.
For it to rank as a high tier, it must have a clean blue with all three parts connecting and showing a good side when inspecting and on idle, so pattern #95 is one of the best patterns for the Mac-10. The MAC-10 | Case Hardened features a heat-treated case-hardened pattern, providing a range of vibrant colors.
