The necklace chain and pendants need to be cleaned with a cloth daily and placed in an air right sealed bag to prevent tarnishing. I neglected to do so one night and the next morning the "gold" had tarnished around the silver pendant. It is a completely different shade from the gold inside the other pendant. I also can never get the chain clean. I rub it with a cloth and always end up with black coming off, no matter how many times I clean the same spot.
Three Sisters Jewelry Response: Thank you for your feedback Kat. We appreciate it! Yes, bronze does need upkeep. It is an ancient metal - sturdy and the finish won't wear off. The bronze is not plated so you don't have to worry about the golden hue rubbing off over time. The residue you find on your polishing cloth is the build-up of lotions and perfumes that create a chemical reaction with the bronze. All semi-precious metals will do this - think of an antique sterling silver tea set. For metals that require little upkeep - we recommend 14K or platinum. They carry a different price tag but they don't require upkeep. Regardless, but semi-precious metals and precious metals will endure the test of time. Thank you!
