Regardless of whether you are making chains from scratch or simply want to replace an annoying lock, you will find inspiration and useful knowledge here.
What is a necklace lock?
A necklace clasp is the small mechanism that holds your jewelry together and makes it easy to put on and take off. There are many variants – from small and almost invisible models to large, decorative locks that become part of the design. The choice depends on the chain's weight, material and who the jewelery is intended for. A good lock must both be functional and fit the chain aesthetically.
The most popular types of jewelry locks
Lobster clasp
Advantages: Very robust and safe. Perfect for heavier chains and everyday use.
Disadvantages: May be a little difficult to open if you have reduced finger strength.
Application: Heavy chains, men's jewelery and jewelery for everyday use.
Spring lock (spring ring)
Advantages: Discreet, light and affordable - good for fine chains.
Disadvantages: Not as durable as the carabiner and can become sluggish over time.
Application: Thin chains, small pendants and light materials.
Magnetic lock
Advantages: Incredibly easy to use - perfect for children, the elderly or if you have joint problems.
Disadvantages: Not ideal for heavy chains. Also be aware of the magnetic influence of medical equipment.
Application: Light necklaces, bracelets and jewelery for daily use.
T-lock / Toggle lock
Advantages: Decorative and easy to handle. Feel good as part of the design.
Disadvantages: Can slide up if the dimensions do not fit perfectly.
Application: Statement jewellery, chunky chains and pearl or leather designs.
Screw clasp and Box clasp
Advantages: Very safe and elegant. Box-clasp often has an additional locking spring.
Disadvantages: Slightly more expensive and requires precision.
Application: Pearl necklaces, classic and exclusive jewellery.
How to choose the type of lock for your necklace
By material and weight
- Fine chains: Spring lock or small carabiner lock fits best.
- Heavy chains: Choose a large carabiner lock or a solid screw lock.
- Pearl necklaces: Box-clasp or screw lock gives a nice and secure result.
- Wire and thread: Use crimps or clamp ends with carabiner or box-clasp.
By target group (children, adults, elderly)
- Children: Magnetic lock or larger carabiner lock for easier use.
- Older: Magnetic lock or T-lock with a good grip surface.
- Party and evening use: Choose a clasp that complements the piece of jewelery – preferably a decorative toggle or box clasp.
For safety and aesthetics
Some locks last better, others look better. For heirlooms and expensive materials, extra security is a good idea - e.g. box clasp with spring lock.
Change or repair your lock - this is how you do it
- Tool: round nose, flat pliers, crimping pliers, jump rings, crimps and possibly soldering tool.
- Replacement with jump ring: Open the jump ring with a pair of pliers, remove the lock, fit the new one and close the ring completely.
- Bead string or wire: Cut off the latch, use crimp beads to attach the new one. For silk thread – consider rebinding.
- Worn parts: Replace locks with defective springs or crooked rings - this will extend the life of the entire piece of jewelry.
Tip: Test the lock several times after installation. An open jump ring is the most common cause of lost jewelry.
Materials and finishes — what should you choose?
- Sterling silver (925): Classic and beautiful, but can get patina. Rhodium plating keeps the color longer.
- Gilded brass: Cheaper and beautiful, but the coating can wear out over time.
- Stainless steel: Very durable and hypoallergenic. Perfect for everyday use.
- Gold (filled or solid): Durable and elegant. Gold-filled is an affordable alternative to solid gold.

What is the difference between a carabiner lock and a spring lock?
The carabiner is strong and durable - perfect for heavy chains. The spring lock is lighter and more discreet, suitable for thin chains.

A large carabiner lock or screw lock provides the greatest security. A toggle lock can also work if it is large enough.

Open the jump ring with two pliers, remove the old lock and insert a new one. For beads and wire - use crimps and crimping pliers for a solid attachment.
Can a magnetic clasp be used for silver chains?
Yes, but be aware of the weight. Magnetic locks are best suited to lightweight chains and should be used with care on medical equipment.
Which lock is easiest for children and the elderly to use?
Magnetic locks and T-locks are clearly the most user-friendly. A larger carabiner can also work fine.
