Hi Jessica, Echeverias are a wonderful species of succulent to grow. An identical species of 2 plants can look completely different from one another depending on the culture provided to the plant. For example, Light, Temperature, Moisture can all affect how a plant colors and grow. Take my Echeveria Lauii for example, notice how large and fleshy the leaves looked when I first bough it? And now the leaves are looking even rounder and more compact with a pinkish hue than the picture shown taken during Jun. My take on your plant, it might be an Echeveria Pulidonis. The pictures you might find online all look really plump and have extreme red linear highlights on the leaves - that is only when you have really good culture with super plump and healthy plants with tonnes of light. Right now, your plant seems to be craving for more light, and the lower more mature leaves are showing signs of the redness on the tips. With more warmth and light during Spring, your plant might look like those you found online.

Not sure which one it is; there are few with long and narrow leaves. But it could be also one of the hybrids (maybe xGraptoveria?). Maybe someone will recognize it...

First thought E. lilicena, but the coloring up is wrong for that. The third picture make me think: Graptopetalum. (this does not help; I know. sorry)

Echeveria ‘Purple Pearl’ ?
