Tom'aliit Kryz and Aliit Kryz: their buy'cese.
The leading Clan of the planet of Kalevala, uses a style of buy'ce that is very common across mandalorians, with the only noticeable change in its structure being the slight dents of the visor's shape.
When it comes to the paint-job, some clan members and those working directly under their command (like guards etc.) use an intricate design, consisting of a blue base, golden painted lines going all around the helmet (and the armor), and bare beskar.
The Clan instead uses a very simple design, with the colors being two shades of blue, white and bare beskar.
In Kalevalan tradition, blue is the color of justice, gold is the color of memory, and white is the color of responsibility (and also death in some cases).
Due to managing in keeping the planet and its Clans peaceful and out of conflicts for hundreds of years, the members of the Clan prefer to paint their beskar'gam with the intricate House's design, since most of them would wear it only ceremonies (and other special occasions), and not so much in their daily life, while the Clan's design was mostly used in times of war, due to its simplicity, and will later make a comeback during the Imperial era.
The other helmets are only worn by two very specific people: the Alori'sol (Duke/Duchess) and their Maan'ii'bor (Heir) (x).
These helmets have been handed down for 800 years, and while they have been modified to accommodate different head shapes (especially if their were aliens), the design of the "face" has remained unchanged, in fact in them the color gold is not painted, but it is a different material (space brass) directly inserted in the helmet, originally done so that their enemies could not cancel their symbols forever by just painting it over.
The rule states that only the Alor of the House and the Heir that they have designated can wear them, but only on ceremonies, since they were not originally designed for battles, and lack much of the equipment needed for them.
An old Clan's belief says that since the helmets have never been repainted or reforged for so long, that if someone wears it for too long they will be able to hear the echoes of the founder of the House, Mand'alor Ko'rang Kryze te Gotal'ad (the Maker), and her daughter/heir, Tom'okar Kryze te Verburyc (the Loyal).
