925 sterling silver blue opal frog ring size 16 17OP

Blue opals are particularly powerful stones for emotional healing and work on the fifth chakra. In general, blue stones bestow serenity and wisdom, as well as fostering communication. 

When light strikes an opal, the silica fragments within the gem bounce it back and refract it in a vivid display of fiery colors. Its beauty depends on the presence of water trapped within the silicon molecules, which, however, evaporates over time and with high temperatures; it therefore requires prolonged immersion in cold water.
