Every piece, every colour. All these designs are made in 18kt white, yellow or rose gold, whichever you prefer, and sized to your wrist. The renders show one colour each, simply because a render has to pick one.

Subject to availability. These are real pieces and they move. Please message before travelling and we will confirm what is on the bench that day.

Images are indicative studio renders showing the style and stone size, not photographs of the individual bracelet. Photographs of the actual piece are sent on request, and you are welcome to see it in person at the Bedfordview viewing room.

Every Prodiam diamond tennis bracelet is made to order in our Bedfordview, Johannesburg workshop: the line of diamonds sourced to order from the certified trade, some cut on our own bench, matched within one colour and one clarity grade along the whole bracelet, in white, yellow or rose gold or platinum, with a firm rand quote by total carat weight and insured delivery anywhere in South Africa.

Diamond bracelet designs: examples we can make

Every diamond bracelet is made to order on our Bedfordview bench. These are rendered examples of standard designs, in the metal of your choice: point at one and say that, at this weight.

These are examples, not a catalogue

We are a working bench, so we can make essentially anything: a design off this page, one of these changed, a piece you have seen elsewhere, a drawing, a photograph, or an heirloom reset into something new. Bring the idea in whatever form you have it and we will tell you what it takes and what it costs, before any work starts.

Message Prodiam on WhatsAppor send it through the contact page

Renders are illustrations of a design, not photographs of a piece in stock. The stones in the pictures are stand-ins; yours is the one you choose, certified, with its own report.

Diamond tennis bracelets: common questions

How much does a diamond tennis bracelet cost in South Africa?

A diamond tennis bracelet is priced on the total carat weight of the line multiplied by the rand-per-carat for the colour, clarity and cut grade you choose, plus the metal. So the cost scales with how many carats sit on the wrist and the quality of the stones, with the diamonds setting most of the figure and the gold or platinum the smaller part.

Because the line is built from many small matched stones rather than one large diamond, the rand-per-carat is far below that of a single big diamond of the same total weight. The bracelets on our current stock sheet are priced on this page, VAT included; a bracelet to your own weight and grade is quoted firm in rands by total carat weight before any work begins.

How many carats is a diamond tennis bracelet?

It depends on the look you want. A fine, everyday line bracelet sits around 2ct to 4ct total, spread across forty or more small matched stones. A statement bracelet runs 7ct to 15ct, and a high-line piece can carry 20ct to 30ct or more. The carat weight is yours to set against budget and wrist size; we calibrate the individual stone size to keep the line even and the spacing right for your wrist length.

Can you match the diamonds across the whole bracelet?

Yes. Every diamond in the line is selected within one colour grade and one clarity grade and calibrated to one diameter, from the certified trade or from stones cut on our own bench, and checked side by side under loupe on the daylight tray before the piece is set, so the bracelet reads as one continuous run of light rather than a row of mismatched stones.

What is the difference between a tennis bracelet and a tennis necklace?

They are the same construction at different lengths. A tennis bracelet is a flexible line of matched diamonds, claw- or channel-set in repeating links, usually 17cm to 19cm to sit on the wrist. A tennis necklace, sometimes called a riviera or line necklace, is the same matched line extended to 40cm to 45cm for the throat, carrying far more total carat weight.

We make both, and we make matched bracelet-and-necklace pairs to the same colour and clarity.

How long does a custom tennis bracelet take to make?

Most tennis bracelets run four to six weeks from approved brief to finished piece: matching and calibrating the line of diamonds, building and casting the links in your chosen metal, claw- or channel-setting each stone, then a box-and-figure-eight safety clasp, hand-polishing, and quality control under loupe and microscope. A longer or higher-carat necklace can take a little more. Tell us your deadline in the brief and we will tell you honestly whether it is achievable.

Can I order a tennis bracelet if I am not in Johannesburg?

Yes, clients commission across South Africa. The brief and stone-grade conversation happens by video or WhatsApp, you approve the carat weight, metal and construction, and the finished bracelet is delivered insured and overnight nationwide via Brink’s or G4S. A written valuation for insurance is included, and wrist sizing is handled with a simple measurement we talk you through.

The Prodiam promise

The quote is free. So is walking away.

Ask us to quote any stone or ring and you get a firm figure in writing within 24 hours, VAT inclusive, with the trade-offs explained in plain English. It costs nothing and commits you to nothing: no deposit, no account, no follow-up campaign. Worst case, you learned the honest number and bought elsewhere better informed.

We actually want you to compare. Buying well means weighing options; it is how we buy rough at the viewings, and it is how you should buy a diamond. Bring any written quote and we will price it like-for-like, and if we cannot beat it, we will tell you so bluntly. Either way you leave knowing where you stand.

One more thing worth knowing: this site shows a selection of our stock, never the full range. Far more passes across the bench than we ever list, so if the exact stone or design you want is not here, ask us for it. It is usually one message away.
