It’s sitting in a dusty velvet box. Or maybe it’s hanging on a plastic display at a flea market, looking a bit lonely next to some chunky 90s resin rings. You’ve seen it: the sharp, silent profile of a woman carved in stark relief. Usually, it’s a black and white cameo necklace, and honestly, it’s the most misunderstood piece of jewelry in your grandmother’s collection. People think they’re "old lady" accessories. They aren't. They are tiny, wearable sculptures made of volcanic stone or sea shells, and they have been cool since at least the third century BC.
History is weird like that.
We tend to associate these monochrome portraits with Victorian mourning or strict Sunday school outfits. But the reality of the black and white cameo necklace is way more punk rock than that. It’s about identity. It’s about taking a piece of hard material—onyx, agate, or even glass—and forcing it to tell a story through contrast. While colorful sardonyx cameos (the orange and white ones) feel warm and traditional, the black and white variety hits different. It’s graphic. It’s moody. It’s basically the original "dark academia" aesthetic before TikTok existed.
The Science of the Stone: Why Black and White?
When you look at a high-quality black and white cameo necklace, you’re usually looking at one of two things: Onyx or Agate.
Geologically, these are banded chalcedony. The magic happens because the stone grows in layers. A master carver doesn't just "paint" the white figure onto the black background; they actually shave away the top white layer of the stone until the bottom black layer starts to peek through. If they go a millimeter too deep? Ruined. The whole thing is trashed.
It’s high-stakes art.

In the mid-1800s, Queen Victoria basically became the world’s biggest influencer for this style. After Prince Albert died, she went into permanent mourning. She wore black. A lot of it. Because of her, "mourning jewelry" became a massive industry. But don’t get it twisted—not every black and white cameo necklace was about death. Often, they were made of Whitby Jet, a fossilized coal found in England, or French Jet, which is actually just black glass. These were status symbols. If you had a finely carved hardstone cameo from Idar-Oberstein in Germany, people knew you had money.
Hardstone vs. Shell: Telling the Difference
You’ve probably seen some cameos that look a bit yellowish or "soft." Those are shell. They’re beautiful, but they aren't the classic black and white powerhouse we’re talking about.
- Hardstone (Agate/Onyx): These feel cold to the touch. They’re heavy. If you tap them against your tooth (gently, please), they clink like a pebble. The white part is often a crisp, milky white that looks almost like marble.
- Molded Glass (Basalt or Vitreous): Often called "black glass" or "vacu-form," these were the affordable versions. Josiah Wedgwood—yes, the teapot guy—made "Black Basalt" cameos that were incredibly popular. They have a matte, stony finish that looks incredible against a white linen shirt.
- Celluloid and Plastic: If the "stone" feels warm or light, it’s probably an early plastic. These emerged in the early 20th century. They’re fun, but they lack the "soul" and the sharp edges of a hand-carved piece.
Why the Black and White Cameo Necklace is Making a Comeback
Honestly, fashion is currently obsessed with "heritage" brands and things that feel permanent. In a world of fast fashion where everything falls apart after three washes, a piece of stone that was carved 100 years ago feels like an anchor.
You’ll see designers like Alexander McQueen or Dolce & Gabbana leaning into this. They take the traditional black and white cameo necklace and flip it. Instead of a demure lady, maybe it’s a skull. Or a spider. But the technique remains the same. The contrast is what draws the eye. In photography, we call it "high-key" contrast. In jewelry, it’s just striking.
It works because black and white is a "neutral" that isn't boring. You can wear a massive onyx cameo with a leather jacket and a band tee, and suddenly you’re not just wearing a necklace—you’re telling a story about the intersection of Victorian gothic and modern street style. It bridges the gap.

Spotting the Real Deal: An Expert’s Checklist
If you’re hunting at an estate sale or browsing eBay, you need to know what you’re looking at. The market is flooded with resin fakes. Resin is just plastic poured into a mold. It’s boring. It has no depth.
- Look for the "Under-Cut": Take a magnifying glass. Look at where the white profile meets the black background. In a real carved cameo, you’ll see tiny tool marks or a slight unevenness where the carver's chisel moved. Plastic fakes are perfectly smooth and "round" at the edges.
- The Light Test: Hold the cameo up to a strong light. If it’s shell, you’ll see the grain of the shell. If it’s agate or onyx, it will remain mostly opaque, but you might see subtle "banding" or stripes within the stone.
- Check the Mounting: Real gold or sterling silver settings usually mean the stone is real. Look for hallmarks like "925," "10K," or "14K." If the metal is peeling or turning green, the "cameo" is likely just a piece of plastic glued into a cheap base.
- The Subject Matter: Most black and white cameos feature "The Anonymous Lady." But if you find one with a specific mythological figure—like Medusa, Athena, or a Bacchante (a follower of Bacchus with grapes in her hair)—the value skyrockets. Those were usually carved by more skilled artists.
Styling Without Looking Like a Museum Exhibit
You don’t have to dress like a character from Downton Abbey to pull this off.
Try layering. A black and white cameo necklace on a shorter gold chain looks incredible when paired with two or three longer, thinner chains. It grounds the look.
Think about textures. A matte black glass cameo looks stunning against silk. A polished onyx cameo pops against denim. If you find a brooch version, don't just pin it to your lapel. Pin it to the velvet ribbon of a choker or even onto the cuff of a button-down shirt.
The secret is the monochrome. Because it’s black and white, it doesn't clash with your outfit. It’s the "Little Black Dress" of jewelry. It’s sophisticated but has a bit of an edge. It says, "I appreciate history, but I’m not stuck in it."

Caring for Your Cameo (Don't Ruin It)
Stone is tough, but it’s not invincible.
If you have a genuine onyx or agate piece, keep it away from harsh chemicals. No ultrasonic cleaners. Just a soft cloth and maybe a tiny bit of dampness if there’s actual dirt in the crevices. If it’s a shell cameo, it can actually "dry out" and crack. Collectors often use a tiny drop of mineral oil once a year to keep the shell hydrated. But for hardstone black and white pieces? They’re pretty low maintenance. Just don't drop them on a tile floor. Agate will shatter if it hits the ground just right.
Where to Buy and What to Pay
You can find vintage black and white cameos anywhere from $20 to $2,000.
A simple 1950s-era "costume" cameo made of glass or plastic might cost you the price of a fancy lunch. But a mid-Victorian onyx cameo set in 15-carat gold? You’re looking at $500 minimum. If the carving is signed—look for tiny scratched names on the back like Saulini or Bistolfi—you’re entering the world of fine art collecting.
Check out sites like Ruby Lane or specialized antique jewelry dealers. Avoid the "mass-produced" stuff on big-box sites if you want something with actual character. You want the one that feels like it has a secret.
Actionable Steps for the Aspiring Collector
- Audit your current jewelry: See if you have any monochrome pieces that would pair well with a high-contrast pendant.
- Search for "Hardstone Cameo" specifically: When shopping, using the term "hardstone" instead of just "cameo" filters out 90% of the cheap plastic and shell imitations, leading you straight to the high-quality black and white onyx pieces.
- Inspect the nose: It sounds weird, but the nose of the profile is the first thing to wear down. A sharp, crisp nose indicates the piece hasn't been handled roughly or "rubbed" over the decades.
- Go to an antique mall this weekend: Don't buy the first one you see. Pick up five different cameos. Feel the weight. Observe the temperature of the stone. You’ll start to "feel" the difference between real craftsmanship and mass production within minutes.
