Buying a ring that is the perfect size can be difficult. If it’s a piece of costume jewelry or a less expensive ring that is not made with gold or platinum, it can be difficult to resize the ring at a jewelry store. For more expensive rings, like engagement or wedding rings, you’ve likely had it properly sized when it was bought, but hand sizes change over time. Plus, taking your ring to a jewelry store can be expensive and it means you’ll be without your ring for a period of time, which may be a no-go depending on upcoming events (you don’t want to risk not having your wedding band in time for your ceremony). That’s why when it comes to getting the perfect fit for your favorite ring, we recommend a ring size adjuster.
Ring size can change depending on a number of factors, including the weather, our physical fitness, hormones, diet and medications. That means that even if you have your ring professionally resized, there is a risk that you could go too small and not be able to wear your ring.
Ring size adjusters are inexpensive and easy to use pieces of plastic that are designed to make oversized rings fit perfectly. The adjusters easily come on and off a ring and can be bought in specific sizes and often cut to the correct length.
Ring size adjusters fit on the bottom of the ring and are typically clear and discreet. Designed for rings that are several sizes too big or only a tiny bit loose, ring size adjusters are a great way to safely show off your favorite piece of jewelry without the risk of losing it.
