Metal Clasps & Terminals for Jewellery

Jewellery Clasps That Combine Security, Fit and Design

Jewellery clasps are among the most important findings in a handmade creation, because they affect the security, comfort, fit and final appearance of the jewellery piece. A properly selected clasp does not simply complete a bracelet, necklace or choker; it also helps the jewellery sit correctly, remain stable and look professionally finished.

At Nikolis Group, you will find a wide variety of necklace clasps, bracelet clasps, cord clasps, chain clasps, rubber cord clasps, Regaliz clasps, terminals, end caps and lobster clasps. The collection covers different technical needs, from simple everyday designs to more demanding professional jewellery lines.

The right clasp should be chosen according to the type of jewellery, the weight of the design, the thickness of the cord, the type of chain, the frequency of use and the aesthetic result the creator wants to achieve. In some designs, the clasp works discreetly, while in others it can become a visible decorative element and take an active role in the design.

What Types of Jewellery Clasps Are Available

The “Clasps” collection includes different mechanisms and finishing components, so that every creator can choose the right finding according to the technique and style of the handmade creation. In the collection, you will find magnetic clasps, screw clasps, T clasps, lobster clasps and parrot clasps, terminals, smart clasps, flat and round clasps, clasps for rubber cords, clasps for Regaliz 10x7mm and metal buttons for closures or decorative applications.

Each category has a different role. A lightweight cord bracelet needs a different clasp from a chain necklace, a choker with a firm fit, or a design made with flat or multiple cords. For this reason, the choice should not be based only on the design, but also on the function.

Magnetic Clasps for Easy and Practical Fastening

Magnetic clasps are one of the most practical options for bracelets and necklaces, as they offer quick and easy opening and closing without requiring complicated handling. Thanks to their ease of use, they are ideal for jewellery worn every day, combining comfort with functionality.

They can be used with a wide variety of materials, such as leather and synthetic cords, rubber, flat and round cords, as well as Regaliz. The suitable clasp is selected according to the dimensions of the material: for flat cords, the width is taken into account, while for round cords, the diameter is checked. For more specialised applications, magnetic clasps specifically designed for Regaliz cords measuring 10x7 mm are also available.

In addition to their functional role, magnetic clasps also contribute to the aesthetics of the jewellery. They are available both in simple, discreet lines and in more distinctive designs, such as geometric, hammered, engraved or irregular shapes, which can highlight the character of a creation.

From a design perspective, they are ideal for minimal, modern, casual and unisex jewellery, especially when combined with leather, rubber, stainless steel components and geometric forms. At the same time, in boho or handmade creations, hammered, embossed or engraved designs work as subtle decorative elements, adding uniqueness without overshadowing the rest of the jewellery.

Lock-Locket Clasps for Secure Fastening

Lock-locket clasps open and close by twisting, offering a secure connection when they fit properly. They are suitable for necklaces, bracelets and jewellery pieces that require a safer fastening, especially when the design is heavier or intended for frequent use.

In the collection, you will find screw clasps in rectangular, oval, geometric and themed designs, as well as options with hearts, stars, locks, crosses, butterflies, safety pins, Hamsa symbols, enamel, zircon and coloured details.

A screw clasp can remain discreet at the back of the jewellery or be placed more visibly when the design has a distinctive shape or decorative value. It is a good choice when the creator wants to combine security, durability and aesthetic interest.

T Clasps for Function and Decorative Use

T clasps consist of a bar and a ring or a specially shaped opening. They are used in bracelets, necklaces, chokers, chains and beaded designs, and are ideal when the clasp is intended to be visible within the design.

Unlike more classic mechanisms, T clasps can be placed at the back, on the side or even at the front, functioning as a decorative element. Designs such as hearts, feathers, flowers, crosses, locks, hooks, arrows, geometric motifs, lucky symbols and organic forms offer more design possibilities.

Some T clasps feature settings for flatback crystals, acrylic stones, enamel or other decorative materials. This allows the creator to adapt the clasp to the colour palette and style of the collection.

Lobster Clasps for Classic and Versatile Use

Lobster clasps are among the most versatile jewellery clasps. They are used in chains, necklaces, bracelets, keyrings and accessories, and they can be easily combined with jump rings and extension chains.

They are selected according to the weight of the jewellery, the size of the connecting ring and the level of durability required by the design. For fine chains and lightweight necklaces, a smaller lobster clasp is sufficient, while heavier creations require a larger and more stable clasp.

In addition to classic options, there are clasps in round, oval, rectangular and flower or heart shapes, with hammered surfaces, zircon designs and coloured details. This means that even a practical clasp can support the final jewellery piece aesthetically.

Terminals and End Caps for Proper Finishing

Terminals, end caps, caps, tubes and special finishing components are essential when working with cords, wires, ball chain or other technical applications. Their role is to secure the end of the material and create a clean transition towards the clasp.

Terminals for flat cords are used with leather, synthetic, suede and other flat materials. Terminals for round cords are suitable for leather, rubber, braided and synthetic cords. The internal size of the setting must correspond to the actual width, thickness or diameter of the material.

In designs with multiple cords, the total size of all the materials together must be calculated. This is important so that the terminal fits correctly and the connection is neither loose nor compressed. A carefully finished end directly affects both the stability and the appearance of the jewellery piece.

Smart Clasps, Adjustable Components and Clasps for Rubber Cords

Smart clasps and adjustable components offer practical solutions for bracelets and necklaces that need length adjustment. “Smart beads” with an internal mechanism or rubber interior can allow the cord to move and work as an alternative to a conventional knot fastening.

Clasps for rubber cords and clasps for flat, round or irregular cords are particularly useful when the material has a specific cross-section and requires the correct fitting. In these cases, compatibility between the clasp and the cord is essential.

How to Choose the Right Clasp for Jewellery

Choosing the right clasp combines technical fit and aesthetics. The creator needs to consider what type of jewellery is being made, which material is being used, how heavy the design is, how often it will be worn and whether the clasp will be visible or discreet.

According to the Type of Jewellery

In bracelets, the clasp must be easy to use, stable and comfortable on the wrist. Magnetic clasps are practical for quick fastening, T clasps can add a more decorative character, while lobster clasps and screw clasps offer more classic or secure solutions.

In necklaces, the overall weight and the position of the clasp must be taken into account. A fine chain necklace may require a discreet lobster clasp, while a more statement necklace with beads, cords or metal components may be better supported by a screw clasp, magnetic clasp or T clasp.

In chokers, the fit is more demanding because the jewellery sits closer to the neck. A clasp is needed that holds the piece securely in place without creating unnecessary bulk. In multi-strand designs, clasps or terminals with suitable openings are needed so that the strands remain aligned.

According to the Cord or Chain

For flat cords, the fitting of the clasp or terminal must correspond to the actual width and thickness of the material. For round cords, the diameter is checked. For Regaliz, special Regaliz 10x7mm clasps are used, while rubber cords require clasps that fit the specific material correctly.

In jewellery with chain, the choice is based on the thickness of the chain, the size of the connecting ring and the weight of the jewellery. The clasp, jump ring and chain must work together correctly so that the connection is stable and aesthetically balanced.

According to Weight and Use

A lightweight bracelet has different requirements from a heavy necklace or a multi-strand design. The greater the weight, the more important the correct choice of mechanism, jump rings, terminals and connection points becomes.

For everyday use, durability, ease of handling and stable fit are the priority. For more decorative or seasonal creations, greater emphasis can be placed on the design, plating, enamel, zircon or personalisation possibilities.

According to the Aesthetic Result

The clasp can discreetly follow the style of the jewellery or become part of the design. A hammered magnetic clasp can add a more handmade feel. A T clasp in the shape of a heart, flower or geometric motif can work as a decorative detail. A screw clasp with enamel or zircon can add colour and shine.

The choice of plating is also important. Gold, silver, rose gold, bronze or other shades should be combined harmoniously with the chains, jump rings, beads, metal components and other findings used in the same creation.

Clasps for Different Handmade Creations

Jewellery clasps are used in many different applications. In cord bracelets, they can be combined with terminals or magnetic mechanisms. In chain necklaces, they can be completed with a lobster clasp and extension chain. In chokers, more stable clasps with a clean profile can be selected. In macramé or tied designs, smart clasps and adjustable components can be used for a more practical fit.

In seasonal creations, lucky charms, keyrings or decorative designs, clasps and metal buttons can also function as aesthetic elements. When a finding has a distinctive shape, themed design or decoration potential, it can be integrated into the overall concept of the creation and not remain limited to a purely technical role.

Design and Production of Clasps by Nikolis Group

Nikolis Group designs and produces metal clasps and findings, placing emphasis on correct geometry, fit, proportions, connection points and final finish. This know-how is important because a clasp must be functional, compatible with the other materials and aesthetically complete at the same time.

In magnetic clasps, the fit of the two parts and the correct correspondence with the cord are examined. In screw clasps, the twisting function is important. In T clasps, the proportion between the bar and the opening matters. In lobster clasps, the spring return of the mechanism is checked, while in terminals, the internal size and fitting depth are key factors.

The collection includes smooth, embossed, engraved, hammered and lined surfaces, as well as themed designs with hearts, stars, flowers, feathers, crosses, locks, lucky symbols, geometric and ethnic motifs. This allows the creator to choose clasps that serve both the technical and aesthetic identity of the collection.

Plating, Finish and Personalisation

Plating affects the shade, texture and visual coherence of the final jewellery piece. A clasp should be properly matched with the chain, jump rings, metal components, beads or terminals used in the same design.

Enamel, zircon, flatback settings and decorative surfaces offer additional possibilities for differentiation. On suitable smooth surfaces, personalised engraving with a logo, initials, name, symbol or short message can also be used, depending on the material, design, available surface and required quantity.

For professional collections, corporate applications or special projects, the possibility of design, production, plating and personalisation can give the final product a stronger identity and enhance the differentiation of the collection.

Frequently Asked Questions about Jewellery Clasps

  • What are the advantages of magnetic clasps?

    Magnetic clasps are a practical choice for necklaces and bracelets, as they close easily with a magnet and do not require complicated handling. They are ideal for jewellery pieces that need to be worn quickly and comfortably, especially designs made with cords, leather, rubber or pieces intended for everyday use.

    To choose the right magnetic clasp, start with the material of the jewellery piece. If you are using flat cord, choose a flat magnetic clasp in the corresponding size, such as 3-5mm, 6-10mm, 15-20mm or 30-40mm. If you are using round cord, choose a round magnetic clasp, such as 1-3mm, 4-5mm or 6-10mm. For Regaliz cords, there are special Regaliz magnetic clasps in 10x7mm.

    The process is simple: first check whether the cord is flat, round or Regaliz, then measure its size, choose the corresponding magnetic clasp and finally select the design and finish that match the style of the jewellery. Simple magnetic clasps are ideal for minimal creations, while engraved, hammered or decorative designs can be used for a more distinctive result.

  • When should I choose a screw clasp for jewellery?

    A lock-locket clasp, is suitable when you want a more stable and secure closure for a jewellery piece. It is often used in bracelets, necklaces and handmade creations that are worn frequently or have some weight, because it opens and closes by screwing and offers greater security.

    Choose a screw clasp when the jewellery needs a durable finishing detail, when the clasp will be visible within the design or when you want it to work as a decorative element as well. The collection includes screw clasps in various designs, such as rectangular, oval, heart, star, safety pin, Hamsa Hand of Fatima and butterfly shapes, as well as designs with enamel or zircon.

    First, decide whether the clasp should be discreet or visible. Then choose the shape that suits the jewellery design. Finally, select the finish, such as metal, coloured enamel, clear zircon or multicoloured details, so that the screw clasp works harmoniously with the overall design.

  • What are toggle clasps and what type of jewellery are they used for?

    Toggle clasps consist of a bar and an opening or ring, through which the bar passes to secure the jewellery. They are both functional and decorative, which is why they are widely used in handmade bracelets, necklaces and choker necklaces, where the clasp is visible and becomes part of the design.

    They are ideal for jewellery with a boho, ethnic, vintage, modern or more artistic aesthetic. They can be used in beaded bracelets, chain necklaces, choker necklaces with cords or metal elements, as well as in designs where you want the clasp to work as a central detail.

    To choose correctly, first decide whether the toggle clasp will be visible or more discreet. If it will be visible, choose a design that matches the theme of the jewellery, such as a heart for a romantic style, a cross for religious jewellery, a geometric shape for a modern result, or a feather and arrow for a boho aesthetic. Then choose the size and finish, so that it matches the weight, length and proportions of the bracelet, necklace or choker.

  • What role do cord ends and lobster clasps play in completing a jewellery piece?

    Cord ends and lobster clasps are essential findings for properly completing a jewellery piece. Cord ends are used to finish and secure the ends of cords, wires, chains or other materials, while lobster clasps work as closures that allow the jewellery to open and close.

    If you are working with flat cord, choose a cord end for flat cord in 3-5mm, 6-10mm or 15-20mm. If you are using round cord, choose a cord end for round cord in 1-3mm, 4-5mm, 6-10mm or 15-20mm. There are also cord ends for various cords, as well as end caps, bead caps, tubes and stoppers for different applications.

    The correct process is as follows: first choose the material of the jewellery, such as flat cord, round cord, wire or chain. Then measure its size. Next, select the right cord end so that it fits properly. Finally, add the lobster clasp that will work as the closure, choosing the size, colour and design according to the style of the jewellery.

  • Are clasps available in different colours and finishes?

    Yes, clasps are available in different colours, platings, designs and finishes, so they can match every type of jewellery. In the collection you will find magnetic clasps, screw clasps, toggle clasps, cord ends and lobster clasps in simple, minimal options as well as more decorative designs.

    For classic jewellery, you can choose metal clasps in discreet platings that combine easily with chains, beads and metal elements. For more modern or youthful creations, there are designs with enamel, zircon, coloured details, hammered surfaces, irregular shapes, geometric motifs, hearts, stars, crosses, padlocks, arrows, animals and floral elements.

    For the best result, match the finish of the clasp with the rest of the jewellery. Metal elements work best with a metal clasp, boho cords can be paired with more distinctive or hammered clasps, while more elegant creations can be completed with zircon, enamel or decorative toggle clasps.
