Opal is a form of silica and water (usually 6 – 10%) that has been hardened over time. Its unique physical properties are influenced by its structure and water content. In contrast to most minerals, opal lacks a defined crystal structure, and is amorphous.
Opal is known to have healing properties for issues related to the intestines and stomach, such as indigestion and acidity. It is also believed to alleviate nightmares and promote restful sleep, as well as benefitting those with pancreatic and hormonal problems. Furthermore, it can positively impact eye health and boost the immune system, making it a versatile and beneficial gemstone.

Opals have a lower hardness with a Mohs scale of 5.5 to 6.5 and are also known for being porous and brittle, making them easily damaged by oils, lotions, water and even life's daily activities. To maintain their stunning color, it's best to avoid wearing them everyday, especially on your hands, which are constantly in motion.
