How do you pick your diamonds?

Each diamond in this bracelet is meticulously inspected and filtered by certified gemologists that are also diamond cutters. We ensure that every diamond meets the highest standards of brilliance and clarity, making your bracelet truly exceptional. We also check the girdles and remove any extremely thin ones to make sure they do not crack or break.

What quality are your diamonds?

All diamonds are:

  • Lab-grown (atomically a diamond)
  • E-F color
  • VS+ clarity (VS1 and above)

Each diamond is individually checked for consistency.

How can I measure my wrist?

You can measure your wrist using a soft tape or even a string, then measure it against a ruler. From there, we typically recommend adding 0.5 to 0.75 inches depending on how you like your fit.

What's the right fit?

Everyone has their preference, but we prefer a secure but not tight fit for everyday wear. It gives you a more comfortable fit and allows for natural wrist movement throughout the day.
A good rule of thumb: you should be able to fit one finger between your wrist and the bracelet comfortably.

Can I resize my bracelet?

Yes, no problem - both before and after delivery. We’ll make sure it fits exactly how you want it.

Please note that pricing may be adjusted depending on the change in size.

  • If the piece is made longer, there will be an additional cost to account for the extra gold and diamonds
  • If the piece is made shorter, the price will also be adjusted accordingly
Does diamond size or width affect how it fits?

Yes, slightly.

Wider or larger carat bracelets tend to feel a bit more structured, so you may want a touch more room for the bracelet to sit and move naturally.

Can I wear my bracelet daily?

YES - our bracelets are designed for everyday wear. That said, like all fine jewelry, removing it during high-impact activities will help preserve it long-term.

Why do you use an under-lock clasp, and is it secure?

Our updated under-lock clasp is designed to improve both security and wearability.

  • Positioned under the wrist, so it’s less exposed
  • Less likely to be bumped or opened accidentally
  • Low-profile design reduces snagging on clothing
  • Maintains a more consistent, clean, and secure closure
How do I choose the right tennis necklace length?

The easiest way is to measure around your neck where you want the necklace to sit, then add or subtract about 1–2 inches depending on your preference.

Necklace length guidlines:

  • 14" – choker style (snug)
  • 16" – classic collarbone fit
  • 18" – slightly longer, relaxed fit
  • 20"+ – longer, ideal for layering

Tennis Necklaces (Men)
Men usually prefer slightly longer lengths for a more relaxed fit:

  • 18" – sits at the base of the neck (clean, fitted look)
  • 20" – most popular for men (comfortable, everyday wear)
  • 22"+ – longer, more relaxed / statement fit

How should a tennis necklace fit?

It should feel comfortable and sit naturally without feeling tight.

You don’t want it restrictive, but also not too loose where it shifts around excessively.

Necklace Length Guide (Everyday Wear)

  • 16"–18" – more fitted, classic look
  • 20"–22" – more relaxed, everyday fit

Can I resize my tennis necklace?

Yes, no problem - both before and after delivery. We’ll make sure it fits exactly how you want it.

Please note that pricing may be adjusted depending on the change in size.

  • If the piece is made longer, there will be an additional cost to account for the extra gold and diamonds
  • If the piece is made shorter, the price will also be adjusted accordingly
What’s the best way to stack tennis necklaces?

There's no right or wrong length, but we usually recommend spacing necklaces about 2 inches apart for a clean layered look - it gives just the right amount of separation.

Style Tip (Our Recommendation)

When layering, we like to use slightly different diamond sizes to create a more balanced, intentional look.

  • Shorter lengths → go slightly thicker
  • Longer lengths → go slightly thinner

This keeps the stack looking clean, balanced, and well-proportioned—nothing feels too heavy or overcrowded.

What kind of clasp do you use for the tennis necklace?

We use an updated under-lock clasp, designed to:

  • Positioned underneath (less exposure)
  • Reduce accidental opening
  • Avoid snagging on clothing
  • Maintain a clean, low-profile look

It stays out of the way so it stays closed.

Will my tennis necklace flip?

One important thing to keep in mind is that all tennis necklaces are prone to flipping to some degree. It really depends on the person wearing it - things like neck shape, movement, and how it sits on the collarbone can all affect it.
That said, some movement is completely normal with all tennis necklaces, it’s part of the design. If minimizing flipping is a priority, the weight of the necklace plays a role and we generally recommend going slightly heavier or wider.

From experience, weight plays a role:

  • Larger/heavier pieces → flip less
  • Thinner/lighter pieces → may flip more

Our 2.00mm size is still a great everyday option and works well for most people, but because it’s lighter, it’s more likely to be affected by the natural shape of your collarbone.

We’ve found that around 2.35mm and above tends to sit more consistently and feel more stable throughout the day.

Do your items come with certification?

We offer a complimentary Certification of Authenticity upon request. If you’d like one included with your order, simply leave the full name and address you’d like listed on the certificate in the notes section at checkout.
