Running Bunny Locket

I've had my necklace for a couple of weeks and have been wearing it 3 to 4 times a week so estimating about 8-12 times. I have never showered in it...just daily wear to work. I noticed tonight that on the back and on the clasp, the gold tarnish is wearing off. For the cost, it should hold up better than this. I love the design with the bunny and it is beautiful for spring jewelry style but it should hold up better given the cost. Hesitant to buy from this brand again if the jewelry does this. I've had cheaper jewelry hold up better. I also had to send back earrings that arrived broken. Thank goodness on those for Nordstrom's return policy.
