The information presented here is based on available sources and provides a comprehensive overview for enthusiasts, buyers, and students of gemology.
History and Lore
Opal’s history is steeped in both admiration and superstition.

The sources highlight the stone’s association with emotional balance and tranquility, suggesting a long-held belief in its metaphysical properties. Modern interpretations continue to emphasize its beauty and versatility, making it a popular choice for contemporary jewelry designs. The sources indicate that opal is frequently featured in bracelets, specifically tennis bracelets, demonstrating its current appeal.
Geological Formation and Sources
The sources do not detail the specific geological processes involved in opal formation, nor do they provide a comprehensive list of mining locations. However, they do indicate that the opals used in jewelry, such as those featured in tennis bracelets, are often “cultured,” suggesting a laboratory-created origin for some stones. The sources mention “blue opal” and “black opal” as varieties used in bracelets, implying diverse origins and colorations. The sources do not specify the geographical origin of the opals used in the featured bracelets.
Gemological Properties
Opal is a unique gemstone, differing significantly from traditional crystalline structures. The sources detail several key properties. The bracelets described feature round-cut opals, often 8mm in size. The stones are set in various metals, including 925 sterling silver, 14K rose gold vermeil, and stainless steel. The sources mention both simulated diamonds and created sapphires alongside opal in some bracelet designs, indicating a combination of gemstones is common.
A comparison of hardness, based on the information available, is not possible as the Mohs scale hardness of opal is not provided in the sources. However, the use of stainless steel as a setting material suggests a focus on durability. The sources specify the approximate weight of some bracelets (e.g., 2.39g for a silver pebble opal bracelet) and dimensions (e.g., bracelet width of 3mm, thickness of 3.2mm, length of 7.5 inches).

Tennis Bracelet Design and Materials
The tennis bracelet style is prominently featured in the sources. These bracelets typically consist of a continuous line of gemstones set closely together, creating a shimmering effect. The sources highlight the use of opal in tennis bracelets as a popular choice for both women and men. Materials used in the construction of these bracelets vary, ranging from high-quality CZ stones and 316L surgical-grade stainless steel to 925 sterling silver and 14K rose gold vermeil. The stainless steel options are described as hypoallergenic, making them suitable for sensitive skin. The sources also mention the inclusion of a 1" extension in some designs, providing adjustability for different wrist sizes.
Symbolism and Metaphysical Beliefs
The sources attribute several symbolic meanings to opal. It is believed to promote emotional balance and tranquility. Sapphires, sometimes featured alongside opal in bracelets, are associated with calming and soothing properties, symbolizing love and affection. The “Pebble Opal” bracelet is described as a reminder of “main character energy,” suggesting a modern association with self-expression and individuality. The October birthstone connection further imbues the gemstone with personal significance for those born in that month.
Care and Cleaning
The sources provide limited guidance on opal care. However, based on the materials used in the bracelets, some recommendations can be made. Sterling silver bracelets should be cleaned regularly with a polishing cloth and stored in a sealed bag or airtight box to prevent tarnishing. Gold vermeil should also be cleaned with a polishing cloth and protected from harsh chemicals. Stainless steel is described as non-tarnish and durable, requiring minimal maintenance. For opal itself, the sources suggest avoiding hot water and harsh chemicals, as many gemstones are delicate.
