Madlodger: The first set are centered on the lobe, the second set are centered just above those, and the third (on the left side only) is a bit closer to the edge of the ear just below where the cartilage starts. I used to have a fourth piercing at the top edge, in the cartilage, but it never properly healed so I let it grow over.
Ruby is my birthstone. 'Trae had the earrings made for me as a gift, so they also have sentimental value. I don't think that sterling silver is non-allergenic, since my maternal grandmother couldn't wear it (she could only wear gold - my mom can wear both gold and silver - go figure).
Piercings, in my family, are a right of passage. I wasn't allowed to get my ears pierced until I reached menarche, and neither will my daughter.
Leon: Ansuz and Berkano (Inspiration and fertility ) are what always came up for me. Laguz (flow) was also quite frequent, and I adopted it as my personal rune.
