Morganites are generally stable and do not lose their color over time under normal conditions. They are a durable gemstone with good resistance to fading. However, it's important to note that prolonged exposure to direct sunlight or excessive heat can potentially cause some color change in morganite over an extended period. Like many gemstones, morganite can be affected by certain chemicals and harsh cleaning agents. To preserve the color and overall appearance of your morganite jewelry, it's best to avoid exposing it to harsh chemicals, such as bleach or sulfuric acid, and to remove your jewelry before engaging in activities that may expose it to potential damage.
