Most tennis bracelets are made in volume, on production lines, long before anyone orders them. Ours are made the other way around. Nothing is built until you order it, and then one bracelet is designed, cast, assembled, set and finished by hand at my bench in Woodside, Queens. Here is what happens between the moment you click order and the moment your bracelet ships.

In short

Every bracelet goes through seven stages: design, casting in solid 14K gold, stone matching, assembly, setting, clasp fitting, and polishing and inspection. Production takes 10 to 15 business days.

1. Design

Every bracelet starts as a 3D model. The most important number in the design is the stone size, because it decides everything else: the size of each setting, the width of each link, how many links fit the length you chose, and the total carat weight. A tennis bracelet has to flex like fabric, so each link is designed to hinge freely against its neighbors without leaving visible gaps between the stones.

The setting style is designed in at this stage too. A four-, three- or two-prong setting needs different seats and spacing, and a bezel setting needs a continuous rim with exactly enough metal to fold over the stone. Our guide to prong vs bezel tennis bracelets explains why those choices matter.

2. Casting in solid gold

Once the design is final, the links and clasp are produced as precise models and cast in solid 14K gold in your chosen color. Solid gold matters. Plated or hollow metal wears through and cannot hold a setting tightly for decades; solid gold can be re-tightened, re-polished and repaired for a lifetime.

Fresh castings come out rough. Each link is cleaned up by hand, and the seats where the diamonds will sit are refined so every stone will sit level and at the same height.

3. Matching the diamonds

This is the stage most people never think about, and the one that decides whether a tennis bracelet looks expensive. The individual stones in a tennis bracelet are small, typically well under a quarter carat each, and they are not individually certified. What makes them read as one even line is careful sorting.

Every Lab-Grown Diamond for your bracelet is checked for size and sorted for color and brightness. A single slightly yellow or dull stone in the middle of a line is obvious from across a room, so any stone that does not match the others is set aside.

A tennis bracelet is only as beautiful as its least matched stone. That is why matching takes as long as it does.

4. Assembling the links

The links are joined one by one into a continuous chain, each hinged to the next. Every joint is checked so the bracelet drapes smoothly in both directions and does not kink or stiffen. A well-assembled tennis bracelet should pour from one hand to the other like a ribbon.

5. Setting every stone

Every diamond is set by hand, one at a time, under magnification.

Prong setting

Each stone is placed in its seat, checked for level, and then the prongs are pushed over the edge of the diamond and shaped so they grip firmly without catching. Each prong tip is then finished smooth. On a two-prong bracelet, each of the two prongs carries more of the load, so the fit of every seat has to be exact.

Bezel setting

Each stone is placed inside its rim of gold, and the metal is gradually pushed in around the entire edge, a little at a time from opposite sides, so the stone stays centered and level. The rim is then burnished smooth and bright, creating the clean circle of gold that frames each diamond.

With forty or more stones on a single bracelet, setting is the longest stage of the whole process, and the one that cannot be rushed.

6. Fitting the clasp

Our tennis bracelets close with a box clasp locked by a safety latch on each side. The tongue of the box clasp is a spring, so it is shaped and tensioned until it closes with a firm, clear click and cannot slip out under a pull. Both latches are fitted so they snap securely over their posts. Read more in our tennis bracelet clasp guide.

7. Polishing and final inspection

The finished bracelet is polished, cleaned and inspected under magnification. Every link is flexed, every prong or bezel is checked, every stone is tested for movement, and the clasp is opened and closed and pulled. Only then is it packed and shipped, free and fully insured.

Why it takes 10 to 15 business days

Casting, matching, assembling and hand-setting forty or more diamonds is careful work. We would rather take the time to get every stone right than ship a bracelet that came off a shelf.
