The Two Most Popular Clasps For Tennis Bracelets

When choosing the perfect Tennis Bracelet, one important detail often overlooked is the clasp. A secure, well-designed clasp not only keeps your bracelet safely in place but also enhances its overall style and wearability. Among the most trusted and stylish options, the Underlock Clasp and Butterfly Clasp stand out as the two most popular choices, especially for Lab Grown Diamond Tennis Bracelets.
The Two Most Popular Clasps for Tennis Bracelets

Underlock Clasp: Secure and Sleek
An Underlock Clasp is a popular choice for tennis bracelets due to its discreet, streamlined design. It features a push-button mechanism that locks securely into place underneath the bracelet, minimizing the risk of accidental opening. Jewelry enthusiasts prefer this clasp for its blend of safety and elegance, making it an ideal option for daily wear.
Why people love the Underlock Clasp:
- Nearly invisible when worn
- Push-to-release mechanism for added safety
- Pairs beautifully with both modern and classic designs
Butterfly Clasp: Elegant and Balanced
The Butterfly Clasp is another beloved option, known for its symmetrical folding design that "opens like a butterfly." It snaps shut with two folding wings that lock on each side of the bracelet. This clasp is often found in Lab Grown Diamond Tennis Bracelets due to its aesthetic appeal and practical functionality.
Benefits of the Butterfly Clasp:
- Offers a smooth, continuous look
- Balanced and comfortable on the wrist
- Easy to open and close, yet very secure
What is the Best Clasp for a Tennis Bracelet?
For Tennis Bracelets, both the Underlock Clasp and Butterfly Clasp are considered top-tier choices. The Underlock Clasp offers an extra layer of protection with a push-lock mechanism, while the Butterfly Clasp provides a sophisticated finish with a hidden locking system. The best lock for you depends on your preference for either a low-profile or a balanced, decorative closure.
What is the safest Tennis Bracelet Clasp?
In terms of security, the Underlock Clasp is often viewed as the safest clasp for Tennis Bracelets. Its push-button mechanism is less likely to open accidentally, giving wearers extra peace of mind, especially when the bracelet features high-value stones like Lab Grown Diamonds.
