It's difficult to determine the exact number of opals in the world, as they are formed naturally and found in various locations, particularly in Australia, which produces about 95% of the world's supply. The quantity of opals can vary widely due to mining activities and natural occurrences. Additionally, opals come in numerous types and qualities, making them highly sought after by collectors and jewelers. Thus, while there are countless opals, an exact count is not feasible.

Opals form from a combination of silica dioxide and water. Over time, water seeps into the ground and dissolves silica from surrounding rocks, creating a gel-like solution. As the water evaporates, the silica gradually precipitates and solidifies, resulting in the formation of opal. This process can take thousands to millions of years, leading to the unique patterns and colors found in opals.

Stones similar to opal include labradorite, which exhibits a play of color known as schiller, and moonstone, known for its adularescence and shimmering effect.

Boulder opals and fire opals also have their own pricing structures, generally falling somewhere in between. Ultimately, the specific characteristics of the opal will determine its market value.

Opal and crystal do not typically grow together, as they form under different geological conditions. Opal is a mineraloid formed from silica gel that fills cavities or spaces in rocks, while crystals, like quartz, form from the gradual crystallization of minerals from molten rock or solutions. However, they can sometimes be found in the same geological environment, resulting in deposits where both may be present, but they do not grow interdependently or in conjunction.

Opal glass is a type of glass that has a translucent, milky appearance, resembling the gemstone opal. It is often made by adding specific minerals, such as calcium and phosphorus, to the glass mixture, which scatters light and creates its characteristic glow.
