Onyx is a microcrystalline quartz called chalcedony formed when silica rich solutions cooled and solidified in cavties within lavas. As the solutions cooled at different rates the characteristic banding of Onyxes was created. Many exhibit black and white banding. If the bands are wide enough black or white segments can be cut and polished to create gemstones. 

Ancient Indian and Persian civilizations believed Onyx would protect from evil , and assist with the journey of life. Onyx is thought to help in times of stress, improve courage, protect the wearer , improve intuition and help individuals move to the next phase in their lives. 

Mother of Pearl is the name given to an irridescent substance called nacre created by certain molluscs.  It forms the shells of pearl bearing oysters  and in fact is composed of the same material as pearls. Nacre is a combination of the mineral Aragonite and a protein called conchiolin. 

Oyster beds of the Pacific and Indian oceans and are an important source of livelihood for the island communities. The oysters health and ability to produce pearls and the nacre on their shells depends on a healthy ecosystem with a good biodiversity so it is in the interest of the pearl farmers to maintain the purity and diversity of the marine environments. Oysters themselves act as a natural cleaner as they filter impurities from the ocean waters. In 2014 Sustainable Development Goals were developed for the Pearl Industry by the UN.
