The History & Evolution of Antique Necklace Clasps
Early Clasps
Throughout history, necklaces have been worn to adorn the neck for either cultural, religious, or aesthetic reasons. The first necklace clasps were simply functional and made from materials such as wood, bone, or metal. As you dive deeper into the world of antique necklace clasps, you’ll notice that early clasps often included T-bar and hook-style clasps designed for ease of use.
Box Clasps and Barrel Clasps
In the Georgian and Victorian eras (late 1700s to early 1900s), various styles of clasps were developed to complement the intricate designs of the necklaces. Box clasps, also known as tab insert clasps, gained popularity due to their secure and discreet nature. Barrel clasps, on the other hand, featured an elongated design with decorative carvings outside of the cylindrical enclosure.
Spring Ring Clasps and Lobster Claw Clasps
During the late 19th and early 20th centuries, the invention of the spring ring clasp and lobster claw clasp revolutionized the world of necklace clasps. These clasps were more secure and easier to use than their predecessors. The spring ring clasp features a circular ring with a spring-loaded mechanism, while the lobster claw clasp is named for its resemblance to a lobster’s claw and comprises a spring-loaded lever.
Magnetic Clasps and Toggle Clasps
In the mid-20th century, magnetic clasps began to make their appearance. These clasps consist of two magnetized pieces that secure a necklace when close to one another. This type gained popularity for its ease of use, making it particularly suitable for those with limited dexterity. Moreover, toggle clasps also became popular for their simple design and artistic appeal. These clasps consist of a bar slipping through a loop made of the same material.
Recognizing the different types of antique necklace clasps will not only help you in determining the age and authenticity of necklaces but also aid you in understanding the value and evolution of these beautiful pieces of jewelry.

9. Patina
When examining antique necklace clasps to determine their value, one important factor to consider is the patina. Patina refers to the natural tarnish that develops on the surface of certain metals, such as gold, silver, and bronze, over time. It can provide valuable information about the age, history, and authenticity of a piece, which will help you to properly valuate your antique necklace.
A well-developed patina can create a beautiful, aged appearance that is desired by many collectors. However, it can sometimes be difficult to differentiate a genuine patina from an artificially created one. Genuine patinas often have irregular textures and may even show some wear, whereas artificial patinas can typically be identified by their uniform appearance.
To further understand how patinas can affect the valuation of antique necklace clasps, here’s a table representing different patina types and their average valuations:

| Artificial Patina with Uniform Appearance | $200 – 300 |
| No Patina | $100 – 200 |
Keep in mind that the age, type of metal, and intricacy of the design can also significantly affect the value of the clasp. For example, gold clasps are generally more valuable than silver or iron ones, and those with more intricate designs or hallmarks will be worth more. Additionally, certain types of clasps, such as hook and box clasps, are rarer and can command higher prices.
Don’t forget to thoroughly inspect the clasps in question, paying close attention to their overall appearance, texture, and wear. This will help you to accurately determine whether the patina is genuine or artificial, and ultimately, provide you with a better understanding of the clasp’s value.
10. Historical Significance
Necklace clasps have evolved over time, reflecting the materials, craftsmanship, and artistic styles of the corresponding era. They are essential not only for practical purposes, but also for their significant role in the historical context of jewelry making.
In the early 18th century, simple hook and eye clasps were common. These basic clasps, often made of bronze or brass, provided a secure way to fasten a necklace. As the design of necklaces and other jewelry evolved, so too did clasps. The mid-18th century saw a rise in the use of more intricate and decorative clasps, such as box clasps and screw mechanisms. These were often adorned with precious stones or intricate metalwork, and became a statement piece in themselves.
The late 19th and early 20th century saw a trend towards using more delicate clasps, like the fishhook clasp commonly found on pearl necklaces from the 1920s. These smaller, more subtle clasps often featured intricate metalwork as well, and could be quite valuable depending on the materials and craftsmanship.
Below is a valuation table with typical values for different types of antique necklace clasps, based on their design, materials, and historical significance.
| Antique Clasp Type | Average Valuation |
