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.

Lapis:

Lapis is a strong blue microcrystalline rock composed primarily of the mineral lazurite. Its value decreases with the presence of white patches called calcite, while small veins of golden pyrite inclusions are often prized. Top quality lapis lazuli comes from Afghanistan, but small quantities are also found in Siberia, Chile, the United States, Pakistan and Canada. It is one of the most valuable semi-opaque stones and is a relatively soft gem, ranking 5.0-5.5 on the Mohs Scale .

First mined in Afghanistan in 6000 B.C., lapis lazuli was used to heal eye maladies and was thought to help one acquire wisdom and serenity. The Romans believed it was a powerful aphrodisiac, while the Egyptians used lapis for cosmetic purposes and often carved it into vases and figurines. The ancient city of Ur had a thriving trade in lapis lazuli as early as the fourth millennium B.C. The name comes from the Latin word “lapis,” meaning stone, and from the Arabic word “azul,” meaning blue.

In the Middle Ages, lapis was thought to free the soul from error, envy and fear. Used by artists during the Renaissance, ground lapis created a beautiful blue pigment for paintings. The stone was inlaid in the columns of St. Issac's Cathedral and the panels of the Pushkin Palace, both in Petersburg. Today, lapis lazuli is traditionally given as a 9th wedding anniversary gift. It is believed to free the wearer of melancholy and strengthen total awareness, creativity and ESP.
