Inclusions of Peridot

Peridot, a gemstone renowned for its vibrant green hue, often contains unique inclusions that not only contribute to its character but also provide valuable insights into its formation and authenticity. Understanding the types of inclusions found in peridot, including both blemishes and internal features, is crucial for gemologists, jewelers, and enthusiasts alike. This detailed exploration delves into the fascinating world of peridot inclusions, offering a professional and informative perspective on these natural characteristics.

1. Internal Inclusions in Peridot

• Lily Pad Inclusions: Perhaps the most distinctive and commonly observed inclusions in peridot are the so-called “lily pad” inclusions. These are stress-induced fractures that appear as tiny, circular, or disk-like cracks. They are a hallmark of natural peridot and are often sought after by collectors for their uniqueness.
• Chromite Inclusions: Small, black chromite crystals can sometimes be found in peridot, offering a stark contrast to its vibrant green. These inclusions are tiny and typically don’t detract from the stone’s beauty.
• Silicate Inclusions: In some cases, peridot may contain silicate inclusions that appear as small, fibrous crystals. These can affect the clarity and color of the stone, depending on their size and distribution.

2. Blemishes Related to Peridot

• Surface Scratches: Due to its relative softness on the Mohs scale (6.5 to 7), peridot can be prone to surface scratches, especially when used in everyday jewelry like rings and bracelets.
• Pitting: Improper handling or exposure to harsh environments can cause pitting on the surface of peridot. These small, concave spots can affect the stone’s luster and overall appearance.
• Abrasion Marks: Wear and tear over time can lead to abrasion marks, which are particularly noticeable on the peridot’s facet edges and junctions. These marks can diminish the gemstone’s brilliance.

3. Evaluating Inclusions in Peridot

• Impact on Value: The presence and type of inclusions can influence the value of peridot. While minor inclusions are generally acceptable, those that significantly impair clarity or color can reduce the stone’s desirability.
• Role in Authenticity: Inclusions can also serve as indicators of authenticity, helping distinguish natural peridot from synthetic or imitation counterparts.

4. Care and Consideration for Inclusion-Bearing Peridot

• Gentle Cleaning: Regular cleaning, using mild soap and lukewarm water, can help maintain the appearance of peridot. It’s important to avoid harsh chemicals or abrasive materials that might exacerbate surface blemishes.
• Mindful Wear: To preserve the integrity of peridot with inclusions or surface blemishes, consider its placement in jewelry settings that offer protection, and be mindful of activities that could expose it to damage.

Understanding the types of inclusions and blemishes in peridot is crucial for appreciating its natural beauty and making informed decisions regarding purchase and care. These internal and external features can significantly impact the gemstone’s appearance, durability, and overall value. While inclusions and blemishes may add character and uniqueness to peridot, they also necessitate thoughtful consideration when it comes to jewelry design and everyday wear.
