Onyx Necklaces
Black chalcedony with a long cameo history
Onyx is banded chalcedony, a quartz family stone whose parallel bands are usually cut so a single color shows: most jewelry onyx is black, produced by treating grey chalcedony, a standard and accepted practice, while sardonyx shows brown-red and white bands and is the traditional cameo material. Black onyx gives necklaces a graphic, high-contrast look in cabochon pendants, faceted beads and intaglio and cameo carvings, set most often in silver or white gold. This guide covers onyx varieties, the black treatment, cameo and bead uses, how onyx pairs with other materials, and care for a hard but knock-sensitive stone.
Onyx necklaces are exquisite pieces of jewelry that showcase the natural beauty and elegance of onyx gemstones. Onyx is a variety of chalcedony, a cryptocrystalline form of quartz, known for its captivating appearance and distinct black color. Its smooth, glossy texture and dark hue make it a popular choice for creating striking necklaces that are both timeless and versatile.
Appearance and Properties:
Onyx is typically black, but it can also feature bands of white, gray, brown, or even red. The contrasting bands or layers add depth and character to the gemstone. These variations in color are often utilized in jewelry designs to create visually appealing patterns and arrangements.
Symbolism and Meaning:
Onyx has been revered for centuries and holds various symbolic meanings across different cultures. It is often associated with protection, strength, and grounding properties. In ancient times, it was believed to have protective energies that guard against negative influences and promote inner strength and harmony.
Jewelry Design:
Onyx necklaces are crafted using polished onyx gemstones that are cut into various shapes such as beads, cabochons, or faceted gemstones. These gemstones are then meticulously strung together to form a necklace, often combined with other complimentary gemstones or metals to enhance their aesthetic appeal.
Versatility in Style:
Onyx necklaces can be designed in a range of styles to suit different tastes and occasions. They can be simple and understated for a casual look or elaborate and ornate for formal events. Onyx pairs well with both silver and onyx, allowing for versatile design options.
Popular Designs:
Common designs for onyx necklaces include single-strand necklaces with spherical or oval-shaped onyx beads, multi-strand necklaces combining onyx with other gemstones, or statement pendants showcasing a large onyx gem as a centerpiece.
Caring for Onyx Necklaces:
To maintain the beauty of an onyx necklace, it's essential to avoid exposure to harsh chemicals, extreme temperatures, and direct sunlight. Cleaning with a soft, damp cloth and storing it in a separate jewelry box or pouch will help preserve its luster and prevent scratches.
Cultural and Historical Significance:
Onyx has a rich history in ancient civilizations such as ancient Egypt, Greece, and Rome, where it was widely used for carving cameos, seals, and jewelry. Its popularity has endured through the ages, and onyx necklaces continue to be cherished pieces of jewelry today.
Geological Properties of Onyx:
Onyx is a type of chalcedony, which is a microcrystalline quartz mineral. Its formation is often associated with the deposition of silica from groundwater. The characteristic bands of different colors in onyx are formed due to the presence of impurities or variations in mineral concentration during the crystallization process. Onyx typically features bands of black and white, but it can also include brown, red, gray, or even blue bands.
Occurrence and Mining:
Onyx deposits can be found in various parts of the world, including countries like Brazil, India, Madagascar, Mexico, Pakistan, and the United States (California and Arizona). Mining operations involve extracting onyx from quarries or mines. The stone is then cut into blocks or pieces, which are subsequently sliced and polished to reveal the distinctive bands and colors. Careful cutting is essential to highlight the beauty of the stone and create the desired shapes for jewelry.
Popularity in Jewelry Design:
Onyx's striking appearance, versatile color variations, and smooth texture make it a popular choice for jewelry designers. Its deep black color and contrasting bands lend a sense of elegance and sophistication to jewelry pieces. Designers often use onyx to create necklaces, pendants, earrings, rings, and bracelets. Onyx pairs well with various metals like silver, gold, and platinum, offering a wide range of design possibilities to match different styles and preferences.

Consumers are drawn to onyx jewelry for several reasons. Firstly, its timeless and classic aesthetic makes it suitable for both casual and formal occasions. The symbolism associated with onyx, including strength, protection, and grounding, adds to its appeal.

Black Stone, Graphic Effect
Black onyx is at its best in designs built on contrast: a polished cabochon in a silver frame, a faceted bead strand against a light neckline, or onyx inlay beside mother of pearl, coral or turquoise in inlay jewelry. Its even black surface also makes it the standard ground for men's signet pendants and for memorial and Victorian-style jewelry, where jet was the historical material and onyx is its durable successor. Faceted onyx beads and pendants trade the mirror polish for bright, dark sparkle.
Because the material is plentiful, onyx necklace value sits in the setting and the making: well-cut cabochons with a level polish and no visible banding where a solid black was intended, tight cameo carving, and sound silver or gold work. Judge a piece in hand by its polish and edges rather than by the stone's rarity, and it will give years of wear.
Common Questions
Is black onyx dyed?
Almost always. Natural chalcedony in an even jet black is rare, so commercial black onyx is grey chalcedony dyed black, a treatment used since antiquity, permanent and stable, and accepted throughout the trade without special care requirements. Sellers should disclose it on request, but it is so universal that black onyx is understood to be treated material.
What is sardonyx?
Sardonyx is onyx whose bands include sard, the reddish-brown chalcedony, layered with white or black onyx bands. Carvers cut cameos from it so the raised design stands in one color against a contrasting ground, and it is one of the August birthstones. In necklaces it appears as cameo pendants, signet-style carvings and banded beads.
How should onyx necklaces be cared for?
Onyx is hard, about 6.5 to 7 on the Mohs scale, but it can chip at thin edges and cameo relief if knocked. Warm soapy water and a soft cloth are safe for cleaning. Keep onyx away from harder gems in storage, and check bead strands for fraying silk, since a broken strand is the main risk to a beaded necklace.
