Pink opal is a fine choice for delicate pink jewelry. Like most other varieties of opal, pink opal is also rather delicate, but in some cases, such as pink Peruvian opal, precious opal can form and mix slightly with chalcedony, which tends to give it a slightly harder composition, though not quite as durable quartz, but still much more durable than precious opal alone. Pink opal has less color play than other types of precious opal. However, like fire opal, it has exceptional body color, which makes it desirable. Top grade pink opal gems are extremely stable and are excellent for beaded jewelry and cabochon designs. They're best suited for pendants, pins or brooches, and can be worn in rings as long as some care is taken to prevent hard knocks and blows. Most pink opals today are sourced from Peru.
