Gemstone treatments refer to various processes used to enhance the appearance and value of gemstones. Common treatments include heat treatment, which improves color and clarity, and fracture filling, where substances are used to fill cracks. These methods can significantly alter a gemstone's look, making it more appealing to buyers. While many gemstones are treated, it's essential for consumers to be aware of these processes. Treatments can affect a gemstone's durability and value, so proper disclosure is crucial. Gemstone sellers often provide information about any treatments, helping buyers make informed decisions about their purchases.
