There was a glitch for some people, they can't upgrade it.
Armor will have pieces of the next armor type's main material. Example; If you have wooden armor of any level upgrade, you will see it has pieces of iron on it. And iron will have gold on it. Ruby armor has three materials; Ruby (main material), diamond and adamant. This also was visible for helmets.
However, Adamant Armor didn't have too much red and didn't even have light gray or black, which are the main colors for it's successor, Champion Armor.
Champion weapons were added later (champion peacemaker, champion solar Cannon, anti champion rifle, champion electric arc, and champion mercenary) after the champion armor was added.
The Adamant Armor was initially a rent-able piece of equipment, introduced in 9.3.0 update. However, it was removed from the Android version of the game in a minor update and never introduced in iOS devices. The adamant armor was reintroduced in 10.0.0 as an upgrade of the ruby armor for both iOS and Android.
As of the 10.3.0 update, the helmet was removed and was replaced by masks. Making the body part of the armor the only armor piece in the game.
Between the 10.4.0 update and the 11.4.0 updates, players got Light Wooden Armor for free after completing the tutorial. You are also rewarded with 5, 10, 15 and a Sniper Rifle.
However, in the 12.0.0 update, Newbie Armor was introduced and was earned as a temporary item.
Newbie Armor looked like Heavy Ruby Armor until 12.5.0.
