You’ve seen it. That distinct, four-leaf clover shimmering against a black backdrop, usually dangling from a gold chain. It’s the Van Cleef necklace black onyx edition, and honestly, it’s basically the "little black dress" of the jewelry world.
While the white mother-of-pearl version is everywhere, there is something deeply sophisticated about the black. It’s moody. It’s grounded. It doesn't scream for attention, yet it’s the first thing people notice when you walk into a room.
The Alhambra collection has been around since 1968. That's a long time to stay relevant. But why does the onyx specifically keep selling out?
The Allure of the Van Cleef Necklace Black Onyx
Most people don’t realize that the "black" in a Van Cleef necklace isn't just a generic dark stone. It’s Brazilian onyx. The Maison is incredibly picky about this stuff. They select stones that are deep, uniform, and have a mirror-like polish.
If you look closely at a genuine piece, the surface should reflect light almost like a pool of dark water.
Why Onyx?
Onyx is a variety of chalcedony. On the Mohs scale of hardness, it ranks around a 7. That's pretty durable for daily wear, unlike the more finicky malachite or turquoise.

- Contrast: The black-on-gold look is legendary.
- Versatility: You can wear it with a literal sweatshirt or a ball gown.
- Symbolism: Jacques Arpels was big on luck. The clover represents hope, faith, love, and luck.
Kinda cool, right?
Spotting a Real Van Cleef Necklace Black (And Avoiding the Fakes)
The secondary market is flooded with "dupes" and flat-out counterfeits. In 2026, the fakes are getting scarily good, but they almost always mess up the tiny details that define the Van Cleef necklace black aesthetic.
The Beading is the Giveaway
Each onyx motif is framed by a row of tiny gold beads. On a real one, these beads are perfectly uniform. They are hand-finished. If the beads look "mushy" or if you can see gaps where they meet the stone, walk away.
Check the Hallmark
Look at the clasp. You should see "VCA" or "Van Cleef & Arpels" along with "Au750" (for 18k gold). Fakes often have shallow, laser-etched engraving. Real ones are stamped deep and crisp. Every piece also has a unique serial number. If you’re buying pre-owned, you should be able to verify that number.
Weight Matters
Onyx and 18k gold have weight. A fake often uses plated brass or plastic, which feels "tinny" or light in your palm. If it feels like a toy, it probably is.
2026 Pricing: What You’ll Actually Pay
Let's talk numbers. Luxury prices haven't exactly gone down lately.
For a standard Vintage Alhambra Pendant in yellow gold and onyx, you’re looking at roughly $2,920 at retail.
The 10-motif necklace—the one that sits like a collar—is a much bigger jump. You’re looking at over $10,000 for that one.

Then there’s the Magic Alhambra. These feature different sized clovers and usually retail higher because of the complexity.
The resale market is wild. Onyx holds its value better than almost any other material in the collection. Why? Because it doesn't "age" or yellow like mother-of-pearl, and it doesn't crack as easily as malachite. You can often find pre-owned pendants for around $2,500 to $2,700, but don't expect a "steal." If the price is too good to be true, it’s a red flag.
How to Actually Care for Your Onyx
People think because it’s black, it’s indestructible. Not true.
Onyx is porous.
If you douse it in perfume or hairspray every morning, that stone is going to lose its luster. Basically, it’ll look "cloudy."
- Last On, First Off: Put your jewelry on after your perfume has dried.
- No Ultrasonic Cleaners: Don't let a local jeweler toss it in an ultrasonic bath. The vibrations can loosen the stone or even cause micro-cracks.
- Soap and Water: A little bit of lukewarm water and very mild soap is fine for onyx. Just dry it immediately with a soft microfiber cloth.
Why This Piece Is Still the Ultimate Status Symbol
It’s the "IYKYK" factor.
Celebrities like Reese Witherspoon and the Princess of Wales have been spotted in various Alhambra pieces for years. It’s because the Van Cleef necklace black version looks intentional. It doesn't look like you’re trying too hard.
There's a quiet confidence in black onyx.

- Visit a Boutique: If you can, go to a physical Van Cleef & Arpels store. Photos don't do the "mirror polish" justice.
- Verify the Stone: If buying pre-owned, ask for a high-res photo of the stone's surface. Ensure there are no "dull spots" which indicate chemical damage.
- Check the Clasp: Ensure the clasp is a "lobster" style that feels sturdy and snaps shut with a distinct click.
- Paperwork: Ensure the serial number on the certificate matches the engraving on the piece perfectly.
This isn't just a jewelry purchase; for many, it's a milestone. Whether it's a graduation gift or a "just because" for yourself, the onyx Alhambra is one of those rare items that actually lives up to the hype. Keep it clean, keep it safe, and it’ll likely be worth more in ten years than it is today.
