Long silver necklaces with reversible pendant (blue/brown)

Two long, silver necklaces for layering. One is a triple layer silver necklace. The other is Stella & Dot’s Sanibel necklace which features a thick silver chain with a faux reversible stone (aqua green blue on one side, brown-ish/black faux stone on the other side). The faux gem has some knocks, but not noticeable unless up close in my opinion. Both are from Stella & Dot.
