I ordered: Paloma's Venezia Stella medallion pendant (link below for reference) for my upcoming birthday. It arrived in the mail two days ago. I think it's lovely but I'm just not 100% on it. I'm wondering if I should exchange it for something else. I want something that's "dressy" - something that I can wear with work clothes but yet also casual. I'm thinking of the Paloma Picasso Luce pendant (that costs $50 more but comes on a longer chain) but again, just not sure. What should I do? I wish I could try on other pieces but I don't live near a store.
