Onyx is a variety of chalcedony quartz that features a fine texture with a smooth black color. Some onyx can display white bands or ribbons against black or brown backgrounds. Mined in Brazil, India, California and Uruguay, most onyx today is color-enhanced to increase its depth of color. It ranks a 6.5 on the Mohs Scale and is an ideal stone for carving. In fact, it is a favorite material of lapidary artists.

Onyx was very popular with the ancient Greeks and Romans. The name comes from the Greek word “onux,” which means fingernail. Legend says that one day frisky Cupid cut the divine fingernails of Venus with an arrowhead while she was sleeping. He left the clippings scattered on the sand and the fates turned them into stone so that no part of her heavenly body would ever perish. In Greek times, almost all colors of chalcedony were called onyx. Later, the Romans narrowed the term to refer to only the black and dark brown colors, while the reddish brown and white onyx became known as sardonyx. Highly valued in Rome, sardonyx was especially used for seals because it was said to never stick to the wax. Roman General Publius Cornelius Scipio was famous for wearing sardonyx.

Worn during mourning in the Victorian age, onyx is now traditionally given as a 7th wedding anniversary gift. It is thought to increase happiness, intuition and instincts. The stone is also believed to cool the yearnings of love and decrease sexual desire.

Jasper:

Jasper is an opaque variety of chalcedony that contains organic materials and mineral oxides. These give it interesting patterns and colorful bands of red, brown, pink, yellow, green, gray, white and blue. Because these color designs resemble landscapes with mountains and valleys, jasper is often named according to its pattern, including the words “picture,” “landscape” or “ribbon” within the name. Picture jasper, for instance, is a petrified or silicated mud that dripped into gas pockets in molten lava. It became super-heated and then solidified to form the unusual banded patterns that are typical of this stone. Today, jasper is found worldwide, with a wide variety located in the western areas of the Unites States. The beautiful stone even adorns the Saint Wenceslas Chapel in Prague.

Jasper was a favorite gem in the ancient world and is referenced in Greek, Hebrew, Assyrian and Latin literature. It was believed to bring on rain and protect in dangerous situations by driving away evil spirits. Nowadays, jasper is thought to balance yin yang energies by stabilizing and healing. Poppy jasper is said to help bring joy into life and opalite jasper is said to help one sleep.
