In fact, the main reason why pearls turn yellow is because of the unstable nature of the minerals it contains internally, which can easily turn into calcite over time.
Here’s a quick remedy if you want to get your yellowed pearls back in shape:We can use diluted hydrochloric acid to soak yellowed pearls, and when choosing a cleaning agent, we must choose dilute hydrochloric acid or hydrogen peroxide. The principle is that hydrochloric acid and hydrogen peroxide can dissolve the yellowed shell of the pearl, thus restoring the surface of the pearl to its original color. In addition, the pearls should not be soaked for too long. The hydrochloric acid should be configured at about 1% to 5%, not too much because too much of the solution corrodes the surface of the pearls. After soaking in hydrochloric acid, the pearls are then scrubbed with water. However, it should be noted that this method is only suitable for pearls that have a slightly yellow surface color. If the yellowing is severe, it is best to send them to a special jewelry counter for cleaning.Warm Tips: Keep an eye on the LuFuture.com app for the latest market updates.
