The carats of the diamonds measure their weight. The karats of the gold indicate the share of pure gold in the metal. These are two different things. For this model, each option from 1 to 10 carats corresponds to a diamond size: the length of the bracelet does not change their diameter. The reference weight is reached from 15 cm. With the same diameter, a longer bracelet has more stones and its total weight increases: about one third more carats at 20 cm. The values in the table are guidelines. The “Carats” options show the estimated weight for the length you choose. | Total weight | Diamond diameter | Number of diamonds (15 to 20 cm) | Look | | 1 ct | ≈ 1.4 mm | ≈ 90 to 121 | A thread of light, very fine, for stacking | | 1.5 ct | ≈ 1.7 mm | ≈ 76 to 102 | Fine and discreet, for every day | | 2 ct | ≈ 1.9 mm | ≈ 69 to 93 | The delicate classic | | 3 ct | ≈ 2.3 mm | ≈ 58 to 78 | The most versatile, from the office to the evening | | 4 ct | ≈ 2.7 mm | ≈ 50 to 67 | A clearly visible sparkle | | 5 ct | ≈ 3 mm | ≈ 46 to 61 | Bold, it gets noticed | | 6 ct | ≈ 3.4 mm | ≈ 41 to 54 | Very luminous | | 8 ct | ≈ 3.9 mm | ≈ 36 to 48 | Spectacular, for a wedding or a party | | 10 ct | ≈ 4.5 mm | ≈ 31 to 42 | The largest in the collection | ## Size guide: which tennis bracelet length should you choose?

Avoid abrasive products and ultrasonic cleaners, which can weaken the prongs. * Store it flat in its box, protected from knocks and separate from your other jewelry. * 14k and 18k gold keep their shine well in everyday wear. 9k gold, which contains more other metals, may tarnish slightly over time: cleaning or polishing restores its shine. White gold is coated with rhodium, which slowly wears off with use: new rhodium plating at a jeweler restores its whiteness. ## Shipping and warranty [See the estimated delivery date ](https://www.simattabijoux.com/en/collection/lab-grown-diamond-tennis-bracelet-gold/#livraison-estimee) * **Free shipping to France and Europe** (home delivery or pickup point). * **Made to order** in the weight, length, gold karat and gold color you choose: delivered in **2 to 3 weeks** (2 more weeks with the optional IGI certificate). * Shipped in its gift box, with a tracking number sent by email. * **2-year warranty**. ## Frequently asked questions ### Is a lab-grown diamond a real diamond? How is it different from a natural diamond? Yes. A [lab-grown diamond, created in a laboratory](https://en.wikipedia.org/wiki/Synthetic_diamond), has the same composition (carbon), the same crystal structure, the same hardness( 10 on the Mohs scale) and the same refractive index (2.42) as a natural diamond. Only its origin is different: it is created in a laboratory in a few weeks instead of being mined. Neither the naked eye nor a jeweler’s loupe can tell them apart. Only laboratory equipment can determine the origin. It should not be confused with cubic zirconia or glass, used as imitations, or with moissanite, a different stone offered in the [French Riviera Silver & Moissanite](https://www.simattabijoux.com/en/collection/moissanite-tennis-bracelet-silver/). ### Is the gold solid? Yes: the setting, the links and the clasp are solid gold, not gold-plated silver. White gold also receives a layer of rhodium that gives it its whiteness. ### 9k, 14k or 18k gold: which one should you choose? The karat number indicates the share of pure gold in the metal: 37.5% for 9k gold, 58.5% for 14k gold and 75% for 18k gold, the rest being an alloy (silver, copper…) that gives the color and strength. 18k gold is the most precious, with the richest shades. It is the jewelry standard in France. 14k gold offers a very good balance between shine, strength and price. 9k gold is the most affordable and may tarnish slightly over time. Scratch resistance also depends on the composition of the alloy and how it is made. The diamonds are identical whatever the gold karat. ### Are the diamonds certified? For this model, the small stones (about 0.01 to 0.35 carat each) do not come with individual certificates. The stated characteristics are D to F color, VS to VVS clarity and an “Excellent” cut. An IGI certificate for the whole bracelet is available as an option, for €60 and 2 extra weeks of lead time. Tick “IGI certificate for the bracelet” before adding to cart. This overall document is different from an individual certificate for each diamond. ### How long does it take to receive it? The bracelet is made to order: allow 2 to 3 weeks, including delivery (2 more weeks with an IGI certificate). The estimated date is shown before purchase for the version you choose. ### Is there a silver version? Yes: the [French Riviera Silver & Moissanite](https://www.simattabijoux.com/en/collection/moissanite-tennis-bracelet-silver/), in 925 silver and D-VVS1 moissanites, from 2 to 6.5 mm wide, and the matching [Rivière d’Azur necklace](https://www.simattabijoux.com/en/collection/moissanite-tennis-necklace-silver/).
