Opal

Opals are gemstones that possess unique characteristics that have found various applications.
== Applications ==
=== Dyes ===
Opals are used as a dye, the vibrant hues and iridescence of opals allow them to be crushed into a fine powder, which is then mixed with other substances to create pigments for dyeing fabrics. This practice is particularly prevalent in certain primitive cultures, where opal dyes are used to enhance the beauty and allure of textiles. Opals are also naturally hydrophobic, making them useful for climbing and swimming gear.
=== Weapon tips ===
Additionally, opals have found use beyond aesthetics. Due to their hardness and sharpness when properly shaped, opals have been employed as weapon tips in historical contexts. These gemstone-tipped weapons possessed a distinct advantage, as they could inflict deep and precise wounds upon adversaries. However, it is worth noting that this usage was limited, as opals were highly valued and not readily available to the average warrior.
=== As water sources ===
Opals serve as a portable water source. Opals, possess an inherent ability to store water in a manner that is safe and relatively sanitary. Opals quenching one's thirst are a popular motif in areas where they are mined.
== Production ==
Opals are typically formed in areas where water has seeped into the ground and dissolved silica-rich minerals. Over time, as the water evaporates, the remaining silica deposits form into opals. These gemstones can be found in various geological settings, including sedimentary rocks, volcanic areas, and even ancient sea beds.
Opal mining can involve both underground and open-pit methods, depending on the deposit's depth and accessibility. In underground mining, tunnels and shafts are excavated to reach opal-bearing layers. Miners carefully extract the opals using hand tools, ensuring minimal damage to the precious gemstones.
