1. What Is Onyx? (and What Is Black Onyx)

Onyx is a form of chalcedony, which is a microcrystalline quartz. In geology, onyx often refers to banded chalcedony—layers of parallel bands, alternating colors such as black, white, brown.

Black onyx is a variety of onyx that is uniformly black. Often what is sold as black onyx has been treated to deepen color, polish finish, or improve durability. Some stones might have natural bands or subtle inclusions, others may be dyed or enhanced.

A black onyx necklace is any necklace where the central decorative element or the bulk of the piece is made from black onyx stone. An onyx bead necklace uses multiple beads made of onyx—round, faceted, or carved—as the primary design element.

4. Types & Styles of Onyx Necklaces

Not all onyx necklaces are the same. The design, size, cut, and style make big differences in both appearance and how you might wear them.

1. Solitaire Pendants & Minimalist Styles

A simple pendant necklace with a single black onyx stone is classic. Shapes include oval, teardrop, round, or geometric cuts. Metals used: silver, gold, gold plated. Works well for everyday wear or with minimal clothing so the stone stands out.

2. Beaded Onyx Bead Necklaces

These use multiple onyx beads, often uniform or graduated in size. They can be classic (black beads only) or mixed with metal beads or other stones. The onyx bead necklace is versatile—it can be boho, spiritual, or even elegant depending on bead size and finish. 

3. Statement & Bib Styles

Large clusters, dramatic designs, bib-style necklaces that cover more area. Often used for special occasions or to make a bold fashion statement. Pairing large onyx pieces with other gemstones or metalwork can be powerful.

4. Vintage, Geometric & Modern Designs

Vintage styles: antique metalwork, filigree, marcasite, ornate settings.
Modern designs: clean lines, geometric shapes, sometimes asymmetrical. Minimalist pendants, sleek choker styles etc.

5. How to Choose a Quality Black Onyx Necklace

Not all onyx necklaces are created equal. Here's what to watch out for so you get one that looks good and lasts.

Authenticity & Material

• Natural vs Treated: Many black onyx stones are treated (dyed, heat treated) to intensify color or improve uniformity. That’s not bad per se, but you should know.
• Uniform Color: A high-quality black onyx should have a rich, deep black color. If it’s too dull, grey, or has patchy color, it might be lower quality.
• Avoid Cheap Imitations: Glass, plastic, or other black materials can mimic onyx. Check hardness, texture, weight. Natural onyx has certain characteristics under magnification.

Metal Settings & Craftsmanship

• The metal (gold, silver, plated, base metals) should be chosen with skin sensitivity in mind.
• Look for secure settings—prongs, bezels should hold the stone tightly.
• Finishing: polish, symmetry, how the stone is cut (cabochon vs faceted) influences both look and durability.

Bead Size, Finish & Color Uniformity (for Onyx Bead Necklaces)

• Beads should be consistently sized (unless intentional design).
• The finish (polished, matte) should be even.
• Uniform color across beads helps—mixed shades (unless intended) can look less premium.

Length & Fit Considerations

• Choker length (~14-16 inches) draws attention to the neck and collarbone.
• Princess length (~17-19 in) is classic, sits at collarbone.
• Matinee, Opera lengths are longer; work well for layering or with high necklines.

6. How to Style Your Onyx Necklace

Here are ways to incorporate a black onyx necklace or onyx bead necklace into your wardrobe in stylish ways.

With Casual Wear

• Pair a simple onyx pendant with a white tee or denim jacket. The contrast between deep black stone and light fabric makes a sleek statement.
• For boho or earthy looks, layer an onyx bead necklace with other natural stone bead necklaces, leather cords, or rustic metals.

For Office / Professional Looks

• Use a single, elegant onyx pendant on a delicate chain with a tailored blouse or shirt. The onyx necklace adds seriousness and polish.
• Combine with minimal metal jewelry—silver or gold studs, slim bracelet—to keep the look cohesive.

Evening & Special Occasion Styling

• Bold statement onyx necklaces or bib-style designs shine with evening gowns or dresses in contrasting colors (white, red, metallics).
• Combine onyx with sparkle—diamond accents, metal embellishments—for drama.

Layering & Mixing Textures

• Layer a choker-length onyx chain with longer chains—perhaps one with a small pendant. Different lengths create depth.
• Mix metals: e.g. a black onyx necklace with gold chain + silver bangles for interesting contrast.
• Pair onyx bead necklace with other bead styles—wood beads, stone beads—for an eclectic look.

7. Care, Maintenance & Myths

Cleaning & Storage Tips

• Cleaning: Use warm soapy water and a soft brush. Avoid harsh chemicals, bleach, or ultrasonic cleaners (depending on how the stone was treated).
• Storage: Store separately in soft pouch or jewelry box to avoid scratches. Beads against metal pieces can scratch.
• Avoid: extreme heat, prolonged sunlight (if dye might fade), harsh household chemicals etc.

How to Keep It Looking New

• Polish gently occasionally.
• Wipe after wearing (sweat, oils, perfumes can dull finish).
• Inspect the clasp or string for wear, especially in bead necklaces—restring if needed.

Myths, Misconceptions & Symbolic Risks

• Some traditions claim wearing black onyx at night or sleeping with it under pillow may have negative energy or cause mental restlessness.
• Beware of claims about curing serious medical issues—these are spiritual or cultural beliefs, not medical advice.
• Be cautious about believing every “protective” claim; focus also on craft, authenticity—style + sentiment matters.

8. Where to Buy & Pricing Guide

• Specialty gemstone or crystal shops (online or brick & mortar) often have more authenticity and better quality.
• Jewelry brands that certify their stones (authentic, treated, or dyed) will often offer more reliable products.
• Market Prices vary widely: simple black onyx pendants can be affordable; large statement pieces or high-carat settings jump in price.
• When buying an onyx bead necklace, the cost depends on bead size, treatment, craftsmanship, and whether other gemstones or precious metals are involved.
