Today's #MinCup23 vote has my favorite: Rhodochrosite!
There's a legend from South Tyrol about King Laurin's Rose Garden. (That part of the Dolomites is actually called Rosengarten).
The legend tells about a Dwarf king who falls in love with a human woman and elopes with her. However, her human relatives decide she must have been kidnapped, and mount a rescue mission.
King Laurin has a famous rose garden in the mountains, planted in honor of a daughter he lost.
The story is quite long, and it is part of the King Dietrich legend cycle. I blogged about it extensively:

Basically it is a story of cultures clashing, prejudice, revenge, regret, and reconciliation. The human knights trample King Laurin's rose garden, and get into a battle with the king defending his honor and his property. The story unfolds from here, but the point is, I always imagined King Laurin's kingdom full of rhodochrosite roses...
