Antique Necklace Clasps: Types, Identification & Value (Guide 2023)

Do you love antiques but are short of space to store them? We get you! In fact, in today’s WFH scenarios, even our rooms are a mess! But hey! Why pick large antiques like pitchers and bottles when even tiny pieces like necklace flasks make up a good investment?

But every investment needs returns, right? And to get them, your clasp must be old, unique, and hallmarked. And you don’t need to rush to any expert to know that! Today, I’ll help you spot and price your old necklace clasp yourself!

Key Takeaways

  • Pick clasps with hand-beaten metal rings, bars, and carvings for good returns. But if you want the new, usable ones, even branded, Art Deco ones are a wise pick!
  • You’ll get antique necklace clasps in four types – barrel, hook, box, and lobster. Of these, the hook and box ones are rare, while others are cheap.
  • Get iron, gold, or silver jewelry clasps for a fast resale. And remember to check their hallmarks and stamps to hike costs.
  • Opt for bare-metal, push, or sliding clasps if you want it handmade! And get the 1900s, screwed ones if you want a machine polish.

How Do You Check If Your Necklace Clasp Is Old & Antique?

Take your necklace flask and hold it between your fingers. Now, open the clasp, put a magnifier over it, and check its ends. If they look v, square, or point-like, it’s an old clasp costing $200 – 300. Also, check its hallmarks for confirmation!

But what if your clasps are rusty and don’t have any hallmarks? Well, in that case, you can check out these features!

  • Metal jump, rings, chain tags, and pins with stamped signs and logos
  • Iron, Brass, and Alloyed Steel walls with grooved edges and fittings
  • 11-12 mm clasps with a 6 mm holder or toggle bar
  • Carved, Beaded, or Gem-fitted faces with hand-polished or gold-plated rings

A Sneak Peak to Vintage Necklace Clasps History

We all loved making simple thread knot jewelry as kids, right? But do you know that the Egyptians used a similar method for the first clasp? They simply used hand-beaten hooks and crude bone or hide rings. So yes, this handmade one obviously resells fast!

Next come the metals! And since it was the royal era, you’d get boxy and loud clasps in this era. But these pure, raw metals lose shine and turn brownish with age. So, their cost drops to $400 – 500. Despite that, you’ll get a good value if your clasp has emeralds and pearls!

The later 1900s pop era was fancier. Like, people wanted all those branded push-style or barrel clasps for easy use! So, makers mechanized the process and added springs to operate the clip. But now, they had no hand touch and were cheaper than before!

4 Types of Antique Jewelry Clasps & Their Valuation

Did your antique shop bombard you with too many clasp designs? Well, don’t worry! You can sort them as per these four types to know their use and average price!

1. Barrel Clasp

Barrel Clasp

As you might guess, barrel clasps are just two grooved cylinders with screws in between. You’ll also see small spring-loaded foam walls and rings on their outer ends. But since they brush regularly, they have high friction. So, they don’t cost more than $30.

2. Hook Clasps

Hook Clasps

Hook clasps are like a simple hook and ring that secures your necklace from both ends. These are very crude, roughly from the 1700s, and are often rusty or dented. Also, check the shape of your hook; if it’s straight, it costs $100 – 125, but if it’s curved, it costs $50 – 60.

3. Box Clasps

Check if your old clasp has a 2-3 mm clip on one end and a hollow cuboid on the other. If yes, it’s a box clasp! Such clasps are 11 – 12 mm tall and have golden walls with shiny gems. Plus, you’ll also see carved faces and ends, costing up to $200.

4. Lobster Claw Clasps

Lobster claw clasps look just like a keychain ring, with a lever at the top. They are thin and compact but have better security and grip than others. Most lobster claw clasps also have rotating bottom pins for better fixing. But since they are new, they cost only up to $50.

How Does a 1900s Necklace Clasp Look?
