Our 5 Best-Selling Diamond Necklaces

Famous Diamond Tennis Necklace Styles

Our extensive collection features over 100 luxury diamond tennis necklace styles, offering something unique for every personality.

Non-Flip Diamond Tennis Necklaces

A non-flip diamond tennis necklace is designed to minimize twisting and keep the diamonds facing forward. This is one of the most practical upgrades for women who want a tennis necklace that looks polished while worn, not just when photographed.

3-Prong Martini Tennis Necklaces

A 3-prong Martini tennis necklace has a lighter setting that keeps the design refined and diamond-focused. It is a beautiful choice if you want a softer, less bulky necklace that still delivers classic diamond brilliance.

4-Prong and Box Setting Tennis Necklaces

A 4-prong tennis necklace gives each diamond a secure, balanced look. Square box settings feel clean and timeless, making them one of the most popular choices for women who want a traditional diamond tennis necklace.

Crown Prong Tennis Necklaces

Crown prong settings add more detail around each diamond, giving the necklace a slightly more decorative look. This style works well for formal occasions, bridal styling, and higher-carat necklaces where you want the setting to feel part of the design.

Bezel Set Tennis Necklaces

A bezel-set tennis necklace surrounds each diamond with gold, creating a smooth, modern edge. It is a strong option for women who want a cleaner profile, added protection, and a more contemporary take on the classic tennis necklace.

Graduated Tennis Necklaces

The best graduated diamond tennis necklace styles feature larger diamonds near the center of the neckline. This creates a natural focal point and gives the necklace a dressier, more dramatic look without adding extra design elements.

Choker and Adjustable Tennis Necklaces

A diamond tennis choker sits higher on the neck, creating a bold, fashion-forward look. Adjustable tennis necklaces offer more flexibility, making them easier to style or layer with different necklines, dresses, and layered jewelry.

Fancy Shape and Multishape Tennis Necklaces

Emerald-shape, heart-shape, pear, princess-cut, marquise, and multishape tennis necklaces are ideal for women who want something less expected than a classic round diamond necklace. These styles retain the luxury of a tennis necklace while adding more personality.

Black, Champagne, and Gemstone Tennis Necklaces

Black diamond, champagne diamond, pink sapphire, and gemstone tennis necklaces bring color, contrast, and individuality to the category. They are perfect for women who love the tennis necklace silhouette but want a more distinctive piece.

How to Choose the Right Diamond Tennis Necklace

Use these practical buying tips to choose the best diamond tennis necklace:

Start with how often you will wear it - For regular wear, choose a lower-carat, non-flip, 3-prong, 4-prong, or bezel-set tennis necklace. These styles are easier to style and usually feel more comfortable for longer wear.

Choose non-flip if fit matters most - If you want the diamonds to stay visible on the neckline, a non-flip diamond tennis necklace is one of the smartest choices. It helps reduce the common issue of the necklace rotating while worn.

Pick the carat weight based on presence - A 4CT–7CT tennis necklace gives refined sparkle. A 10CT–15CT necklace feels more luxurious and noticeable. A 20CT–25CT+ necklace is best for formal events, milestone gifting, and statement styling. Read our guide to know the best carat weight for an everyday tennis necklace.

Match the setting to your lifestyle - Prong settings show more of the diamond and create strong brilliance. Bezel settings feel smooth and secure. Crown prong settings add detail. A 4-prong box setting is a classic choice for timeless tennis necklace styling.

Think about neckline and length - A shorter tennis necklace or choker works beautifully with strapless, off-shoulder, and open necklines. A 16-inch style is one of the most versatile choices because it usually sits near the collarbone.

Use metal color to shape the mood - White gold gives a bright, modern look. Yellow gold feels warm and classic. Rose gold softens the design. Platinum is best if you want a cool-toned metal with excellent durability.

Choose diamond shape carefully - Round diamonds are the most classic. Emerald shapes look clean and architectural. Heart-shaped and multishaped necklaces feel more personal. Black or champagne diamonds create a bolder fashion statement.

For gifting, stay timeless - If you are buying for someone else, a non-flip 4-prong, bezel-set, or classic round diamond tennis necklace is usually the safest choice because it works with many styles and occasions.

Frequently Asked Questions

A luxury diamond tennis necklace can cost from under $15,000 to $90,000+ when crafted with high-carat natural diamonds, exceptional quality, and expert craftsmanship. On average, people spend $3,000 to $13,000 on a diamond tennis necklace. Smaller 4CT–7CT luxury tennis necklaces are usually more accessible, while 10CT, 15CT, 20CT, and 25CT+ styles cost more because they use larger or higher-quality diamonds. 

Lab-grown diamond tennis necklaces provide the same timeless brilliance at a significantly lower price, making larger carat weights more accessible. The final cost depends on total carat weight, cut, color, clarity, necklace length, metal type, setting style, craftsmanship, and certifications.

A secure box clasp with a safety latch is one of the best choices for a diamond tennis necklace because it helps keep the necklace closed and secure. For higher-carat tennis necklaces, clasp security is especially important because the piece has more value and weight. Read our guide on necklaces and bracelet clasps to choose the right one.

Yes, but it works best when the tennis necklace is the main piece. Pair it with a delicate pendant, thin gold chain, or shorter choker instead of layering it with another heavy statement necklace. Keep the lengths slightly different so the necklaces do not rub or tangle.

In many cases, yes. We offer free resizing to shorten a diamond tennis necklace by removing links, depending on the design and setting. Adjustable tennis necklaces are also available for more flexibility with different necklines.

Use a soft brush, warm water, and mild soap to gently clean the necklace. Dry it with a soft lint-free cloth. Avoid harsh chemicals, bleach, chlorine, and abrasive cleaners. For high-carat or frequently worn necklaces, professional cleaning and inspection are recommended. Read our essential diamond jewelry cleaning tips to keep your piece in pristine shape.

Yes, insurance is a smart choice for a high-value diamond tennis necklace. Because tennis necklaces often contain many diamonds and higher total carat weights, insurance can help protect the piece against loss, theft, or damage. Keep your receipt, appraisal, certification details, and photos for your records. 

Yes, diamond tennis necklaces can be repaired if a link, clasp, or setting becomes loose or damaged. It is best to stop wearing the necklace immediately and have it inspected by a jeweler to avoid losing diamonds or causing further damage.

A diamond tennis necklace should be professionally inspected at least once a year, especially if you wear it often. The jeweler can check the clasp, links, prongs, settings, and diamonds to make sure everything is secure.
