Polished black chalcedony, set for contrast
Onyx earrings use black onyx, the solid black form of chalcedony quartz, cut most often as smooth cabochons, beads and flat tablets and set in studs, drops, hoops and cluster designs. The stone's value in earrings is graphic: a deep, even black with a glossy polish that contrasts sharply with silver, white gold, yellow gold and diamonds, and frames the face with a clear, formal outline. Black onyx for jewelry is usually chalcedony dyed black, a standard and permanent trade treatment that sellers should disclose. This guide covers the stone and its treatment, cabochon and bead cuts, contrast settings and pairings, matching pairs of opaque stones, and straightforward care for regular wear.

Geological Properties of Onyx:
Onyx is a type of chalcedony, which is a form of microcrystalline quartz. Its geological properties include:
Composition: Onyx is primarily composed of silicon dioxide (SiO2), the same mineral that makes up quartz and agate. Its black and white banding is created by alternating layers of black and white chalcedony.
Formation: Onyx forms in the cavities of volcanic rocks, as well as in sedimentary and metamorphic environments. It often occurs in concentric layers that result from the slow deposition of silica-rich solutions.
Color Variations: While black and white onyx is the most well-known variety, onyx can come in a range of colors, including brown, red, yellow, and green. These colors are achieved through impurities or exposure to different minerals during formation.
Historical Significance:
Onyx has historical significance dating back to ancient civilizations:
Egypt: The ancient Egyptians used onyx in the creation of amulets and jewelry. They believed it had protective properties and used it in the crafting of scarabs and other symbolic artifacts.
Roman Empire: Onyx was a popular choice for cameos and intaglios during the Roman era. These intricate carvings were often used as seals or personal adornments.
Medieval Europe: Onyx was believed to have protective qualities in medieval Europe and was sometimes engraved with images of gods and mythological creatures.

An opaque black stone shows its setting more honestly than a transparent gem: every edge, bezel and prong is silhouetted against the black, and the polish of the metal is reflected in the cabochon's dome. Good onyx earrings therefore use clean, simple settings, a smooth bezel or minimal prongs, metal finished to the same standard as the stone's polish, and pairs matched in shape and dome height, since two black shapes beside the face invite exact comparison even though there is no color to match.
Care is straightforward because chalcedony is a hard, durable quartz. Clean onyx earrings with warm soapy water and a soft cloth, check bezels and posts as with any earring, and store pairs so the polished domes do not rub against harder stones or metal edges that could dull the finish. The dyed color is permanent under normal wear, so no special protection from light or water is needed beyond ordinary jewelry care and keeping settings secure. That durability, combined with a price far below that of transparent precious stones of similar visual weight, is why black onyx has remained a staple earring stone across formal, evening and everyday ranges for generations of wearers.
The black chalcedony sold as black onyx is usually dyed black, and has been for a very long time: natural chalcedony is typically greyish and banded, and dyeing produces the even, solid black jewelry requires. The treatment is permanent and stable, does not change care, and should be disclosed by the seller as a matter of normal trade practice.
Onyx is opaque, so faceting adds little: its beauty is in a smooth, highly polished surface and an even black depth, which the domed cabochon cut shows best. Flat tablets, beads and occasional faceted tops for a sharper flash are also used. In earrings the cabochon's clean dome gives the crisp black shape the design depends on.
Silver and white gold give a cool, high-contrast black-and-white effect, yellow gold gives a warmer, classic contrast, and small diamonds or white stones are often set as accents against the black. Onyx also pairs with mother of pearl in black-and-white designs and with red stones such as coral or garnet in traditional combinations.
