Our jewelry is crafted using high-quality materials, including sterling silver and 14K gold-filled over brass. While these metals are generally safe for most individuals, some people may have sensitivities or allergic reactions to certain metals. Sterling silver is typically composed of 92.5% pure silver, with the remaining percentage often consisting of other metals, such as copper, and in some cases, trace amounts of nickel. Similarly, our 14K gold-filled pieces are made by bonding a layer of 14K gold over a brass core, and brass may contain nickel, which can cause reactions for individuals with specific sensitivities. We take great care in selecting the materials for our products, but due to the natural variations in metal alloys and manufacturing processes, we cannot guarantee the complete absence of trace elements like nickel in all pieces. If you are concerned about potential allergies or have a known sensitivity to certain metals, we recommend consulting with a medical professional prior to making a purchase. By purchasing from our site, you acknowledge that you are aware of the potential for allergic reactions to metals and assume responsibility for determining the suitability of our jewelry for your personal use.
