925 Silver Precious Opal Decorated Ring
Opal is a semi-precious gem that has a significant water content in its structure. More precisely, it has a chemical structure SiO2.nH2O and is a mineraloid. A mineraloid is a mineral that has no formal atomic structure; unlike the majority of other minerals found in nature. It is primarily composed of hydrated silica, a form of silicon dioxide but with additional water in its structure. The remaining 10 or so percent of opal is water. The ring is made from 925 sterling silver, a high-grade silver alloy that is both durable and beautiful. The sterling silver has been expertly crafted into a simple yet elegant band, which allows the opal to take center stage. The ring's design is timeless and versatile, making it suitable for any occasion, from casual wear to special events.
