I was browsing an estate sale in Charleston last summer when I saw it. Tucked behind a pile of costume jewelry was a strand of deep, oxblood red beads that looked almost too perfect. The weight was there. The coldness against the skin was there. But when I looked closer, the tiny "growth rings" weren't right. It was a fake. Honestly, buying an antique coral bead necklace today is a bit of a minefield because the market is flooded with dyed bamboo coral and glass imitations that can fool even seasoned collectors if they aren't paying attention.
Real antique coral isn't just a piece of jewelry. It’s a biological record. For centuries, Mediterranean coral (Corallium rubrum) was the gold standard, harvested from the depths of the sea and traded across the Silk Road. It’s porous. It’s organic. It feels different than plastic or stone. You’ve probably seen those bright orange-red strands in your grandmother’s jewelry box and wondered if they were worth anything. They usually are. Sometimes a lot.
The history of these pieces is actually pretty wild. In the Victorian era, coral was given to children because people genuinely believed it protected them from the "evil eye" and various illnesses. If you find a very short, delicate antique coral bead necklace, there’s a good chance it was originally a christening gift.
Spotting the Difference Between Real Coral and the Fakes
How do you know if you're holding history or a piece of painted wood? It’s harder than it used to be. Most "coral" you see at flea markets is actually dyed white coral or "sponge" coral.
Look for the fingerprint. Real Mediterranean coral has a very specific structure. If you have a magnifying glass, look for extremely fine, parallel striations. They look like the grain in wood but much more subtle. If the bead is perfectly smooth with no texture at all, it’s likely glass or plastic. If it has little circular "cells" or looks pitted like a sponge, it's a different species of coral entirely—not the precious antique variety that collectors want.
Acetone is a trick some people use, but I wouldn't recommend it on a piece you don't own yet. You take a Q-tip with a tiny bit of nail polish remover and swipe an inconspicuous spot. If the Q-tip turns red, it’s dyed. Simple. But what if it’s "reconstituted" coral? That’s basically coral dust mixed with resin. It’s the "particle board" of the jewelry world. It feels light. It lacks that stony clack sound when two beads hit each other.

The Color Spectrum
Most people think of "coral" as that bright, neon orange. But in the world of an antique coral bead necklace, the colors vary massively.
- Oxblood (Moro): This is the holy grail. It’s a dark, intense red that almost looks like a black cherry. It’s rare. It’s expensive. Most of it came from the waters around Italy and Japan.
- Angel Skin (Pelle d'Angelo): This is a very pale pink, sometimes with a hint of white. It was incredibly popular in the late 19th century. If you find a genuine antique strand in this color without heavy staining, you’ve found a treasure.
- Salmon: This is the most common "vintage" look. It’s a warm, earthy orange-pink.
Why the Victorian Era Changed Everything
Victorian jewelers were obsessed with the natural world. They didn't just string beads; they carved them into tiny acorns, roses, and even mythological figures. A carved antique coral bead necklace from the 1860s is a masterpiece of hand-tooling.
During this time, Naples was the undisputed center of the coral trade. The Ascione family, who started their workshop in 1855, are still the gold standard for historical provenance. If you ever find a piece with their mark or a documented history from the Torre del Greco region, the value triples instantly.
But there's a darker side to the history too. Coral was often part of the "Grand Tour" souvenirs. Wealthy Europeans would travel to Italy and bring back these necklaces. Because the demand was so high, even back then, people started making "French jet" or glass versions to keep up. So, just because a necklace looks 150 years old doesn't mean it's real coral. People have been faking this stuff since the beginning.
The CITES Reality and Legal Hurdles
This is the part that isn't fun, but you need to know it. Corallium rubrum and other precious corals are heavily regulated today. You can't just ship an antique coral bead necklace across international borders without a mountain of paperwork.

The Convention on International Trade in Endangered Species (CITES) keeps a close watch on this. If you are buying a piece from overseas, you must ensure it has a certificate of antiquity or a CITES permit. Without it, Customs can—and will—seize the item and destroy it. This is why buying from reputable domestic dealers is usually the smarter move. It's not just about the money; it's about the legality of owning a protected organic material.
Caring for Your Investment
Coral is soft. It’s roughly a 3.5 on the Mohs scale. For context, a diamond is a 10 and your fingernail is about a 2.5. This means your perfume will kill it.
Seriously. The alcohol and chemicals in hairspray, perfume, and even sweat will eat away at the polish of the beads. Over time, a shiny oxblood necklace will turn dull and chalky. This is called "dying." To prevent this, you should always put your jewelry on last. After the spray has dried. After the lotion has sunk in.
When you're done wearing it, wipe it down with a soft, damp cloth. Never, ever put it in an ultrasonic cleaner. It will shatter. Just a bit of lukewarm water and maybe a drop of pH-neutral soap if it's really grimy.
What Determines Value in Today's Market?
It’s not just about the color. You have to look at the "matching." In a high-quality antique coral bead necklace, the beads should be graduated perfectly. The transition from the tiny beads at the clasp to the large bead in the center should be seamless.

Weight is another huge factor. Since coral is sold by the gram in the wholesale world, a heavy, dense strand of large beads is worth exponentially more than a thin strand of "twig" coral. If you have a strand where the center beads are larger than 10mm, you are looking at a serious piece of jewelry.
Look at the clasp too. Antique pieces usually have 14k or 18k gold clasps, often with a small piece of coral inset into the metal itself. If the clasp is cheap base metal or a modern lobster claw, the beads might be old, but the necklace has been re-strung—or the beads aren't as old as the seller claims.
The Misconception About "Red"
I hear this all the time: "If it's not deep red, it's not real coral." That's just wrong. Some of the most valuable coral in the world is the pale "Angel Skin" variety. In fact, in certain markets like Taiwan and China, the pale pink and white-streaked varieties are currently fetching higher prices at auction than the traditional red.
Also, watch out for "Apple Coral." You'll see this a lot in Southwestern jewelry. It's real coral, but it's not "precious" coral. It's a different species that is naturally very porous and almost always filled with plastic resin to make it stable enough to wear. It's pretty, but it shouldn't be priced like a Victorian Mediterranean strand.
Navigating the Auction World
If you’re looking to buy, skip the big-box sites where "antique" is a keyword used loosely. Look at specialized houses like Sotheby’s or smaller, reputable estate jewelers who have a gemologist on staff.
Ask for a report. While GIA (Gemological Institute of America) is the big name, they don't always provide the "origin" of coral unless specifically requested and paid for. However, they can definitely tell you if it's been dyed or treated. If a seller refuses to let you have the piece appraised during a return window, walk away.
Actionable Steps for Collectors
If you’ve inherited or recently purchased a strand, here is how you should handle it to ensure it keeps its value and stays legal.
- Check the Stringing: Silk thread rots over decades. If the thread looks frayed or grey, take it to a professional to be re-strung. Ask them to "knot between every bead." This prevents the beads from rubbing against each other and ensures that if the string breaks, you only lose one bead instead of the whole strand.
- Storage Matters: Don't toss coral into a tangled pile with gold chains. The metal will scratch the coral. Store it in a silk pouch or a velvet-lined box by itself.
- Document Everything: Take high-resolution photos of the grain of the beads. Keep any receipts or original boxes. If you ever decide to sell it, having a "paper trail" that proves it was purchased before the major CITES restrictions is worth its weight in gold.
- Verification: Use the "tooth test" sparingly. Like a pearl, real coral will feel slightly gritty against your tooth, whereas glass or plastic will feel smooth. It’s not foolproof, but it’s a quick field test.
- Appraisal: Get an insurance appraisal every five years. The price of precious coral has spiked significantly in the last decade due to harvesting bans, and your old policy might not cover its current replacement cost.
