Opal is a beautiful and unique gemstone that is known for its play of color, which is the way that the stone displays different colors as it is viewed from different angles. Opals can be found in a variety of colors, including white, black, and blue, and are often used in jewelry as pendants, earrings, and rings.
Opals can be fragile and are sensitive to extreme temperature changes, so they should be handled with care. It is also important to store opals away from other jewelry to avoid scratches and damage.
Overall, opals are a beautiful and unique gemstone that can make a great addition to any jewelry collection.
