Necklace - High VS Low

I normally spend quite a bit on accessories that I might never wear {part of my oniomania condition}. I recently found these two necklaces that I MUST have! A two-toned necklace from BCBG and a fringed necklace from Etsy. {Pictures below} To spending $150 plus on necklaces that I might never wear seems a bit crazy so similar styles at Forever 21 for less! Contemplating if I should but the cheaper ones or just spend the money on the ones I want. Interesting fact: All 4 Forever 21 necklaces would only cost around $50!
