- Onyx is the parallel-banded variety of chalcedony, a silicate mineral. Agate and onyx are both varieties of layered chalcedony that differ only in the form of the bands. Onyx has parallel bands, while agate has curved bands. The colors of its bands range from black to almost every color. Specimens of onyx commonly contain bands of black or white or both. Onyx, as a descriptive term, has also been applied to parallel-banded varieties of alabaster, marble, calcite, obsidian, and opal, and misleadingly to materials with contorted banding, such as “cave onyx” and “Mexican onyx”.
- Elvis Presley (Wikipedia)
Elvis Aaron Presley (January 8, 1935 – August 16, 1977), commonly referred to by his first name, Elvis, was an American singer and actor. Known as the “King of Rock and Roll”, he is regarded as one of the most significant cultural figures of the 20th century. Presley’s energized interpretations of songs and sexually provocative performance style, combined with a singularly potent mix of influences across color lines during a transformative era in race relations, brought both great success and initial controversy.
