A tennis bracelet is a classic and elegant piece of jewelry that features a continuous line of individually set, closely spaced gemstones, typically diamonds, although other gemstones can be used as well. The term "tennis bracelet" became widely recognized after an incident during a tennis match involving the famous tennis player Chris Evert in the 1987 US Open. She asked the officials to stop the match because her diamond bracelet had come undone and fallen off her wrist. Since then, this style of bracelet has been commonly referred to as a "tennis bracelet."
Key features of a tennis bracelet include:

Gemstones: Tennis bracelets are most commonly adorned with round-cut diamonds, although other gemstones like sapphires, emeralds, or rubies can be used to create colorful variations.
Setting: The gemstones are typically set in a metal, such as white gold, yellow gold, or platinum, with prongs that hold them securely in place while allowing maximum light to pass through, enhancing their brilliance.
Clasp: Tennis bracelets usually have a secure clasp, often a box clasp with a safety latch, to ensure the bracelet stays fastened while being worn.
Design: They are characterized by their consistent row of gemstones, creating a dazzling and continuous look that elegantly wraps around the wrist.

Tennis bracelets are a versatile and timeless choice for jewelry, suitable for various occasions, from formal events to everyday wear. They can be worn alone or stacked with other bracelets for a more personalized look. The choice of metal and gemstone can vary, allowing you to select a tennis bracelet that suits your style and preferences. Whether it's a gift for a loved one or a special treat for yourself, a tennis bracelet is a symbol of enduring elegance and beauty.
