18k gold jewelry: how to recognize hand-shaped 750/1000 gold wire

Choosing 18k gold jewelry means understanding what that number really involves: metal composition, hand-shaping, care. At Atelier Paulin, 18k gold refers to a solid gold wire made of 75% pure gold, also known as "l'Or de la tradition Française" — the gold of French tradition. Since 2014, the Parisian atelier has hand-shaped this single length of precious wire into personalized 3D jewelry, never carved or engraved. This article covers the composition, available colors, real turnaround times, and care of 18k gold jewelry, so you can choose with confidence.

What "18k gold" really means in artisan jewelry

750/1000 gold, known as 18k gold, is a solid gold wire made of 75% pure gold. It's what's called "l'Or de la tradition Française" — a historic reference in French goldsmithing. At Atelier Paulin, every 18k gold piece is hallmarked, certified, and hand-shaped by one of the Maison's artisan jewelers, from a single length of precious wire, never assembled from multiple soldered elements.

The nuance matters: in 18k gold jewelry, there's no plating or outer layer involved — it's a solid wire, gold all the way through. The hand-shaping process involves sculpting this wire by hand, letter by letter for names, then work-hardening the entire piece once the design is complete, never letter by letter. This work-hardening gives the metal its shape memory and resilience.

To understand exactly what that 750 number changes in terms of weight, tone, and durability, our dedicated article breaks down every technical aspect: 18k Gold 750: What That Number Really Changes for Your Jewelry. It's the companion read for anyone who wants to go beyond the definition and understand the real impact on a piece worn daily.

The three colors of 18k gold jewelry: yellow, rose, white

Unlike 14k gold-filled, which only comes in yellow and rose, 18k gold comes in three tones: yellow, rose, and white. This range lets you match the piece to your skin tone or to pieces you already wear daily.

Yellow 18k gold keeps the traditional shine of pure metal. Rose gold gets its tone from a subtle alloy that gives it warm undertones. White gold, meanwhile, offers a cooler, more understated brilliance, close to silver but with the density and structure of solid gold.

If you're torn between 14k gold-filled and 18k gold in a rose tone, the color difference is nearly invisible to the eye — the real distinction lies in composition and budget. To compare both rose options directly, our dedicated collection shows the available pieces: shop rose 14k gold-filled jewelry. This comparison helps you choose between the accessibility of gold-filled and the solid density of 18k gold, depending on how you plan to wear the piece and your budget.

Either way, every piece stays hand-shaped, never cast or mass-assembled: the wire is sculpted directly into its final form.

Hand-shaping and delivery times for 18k gold jewelry

In artisan 18k gold jewelry, hand-shaping time differs from sterling silver or 14k gold-filled. Plan for 2 to 5 business days of hand-shaping at the atelier for an 18k gold piece, compared to 1 to 3 business days for sterling silver and 14k gold-filled. This is the time the artisan spends sculpting the wire, shaping each letter one by one, then work-hardening the entire piece.

This hand-shaping time is separate from home delivery time, which is 2 to 5 days, shipping included. The two add up: your hand-shaped piece arrives after both steps.

For customers based in Paris, two options are available exclusively in-store: come have your piece personalized directly at the atelier, in about thirty minutes, or have it delivered by courier the same day. It's a service few ateliers offer, letting you leave with your 18k gold piece the very same day.

Every piece hand-shaped to order arrives in a jewelry box, with no pouch or separate certificate: the box itself is the presentation piece.

Caring for 18k gold jewelry day to day

750/1000 gold requires no special care. Cleaning with lukewarm water and mild soap, followed by drying with a soft cloth, is enough to keep the gold wire's shine over time. Unlike sterling silver, which can develop a light, natural, and reversible tarnish from contact with air or moisture, 18k gold doesn't oxidize.

This stability makes it a smart choice for a piece worn every day, including through varied activities. Hand-shaped 18k gold wire also benefits from laser micro-welding reinforcement at tension points: the wire remains a single hand-shaped length, and the micro-welding simply reinforces the areas under the most stress.

For the most delicate pieces, with fine wire sculpted into patterns or letters, it's still wise to avoid sharp impacts and repeated handling that could distort the shaped design. These are common-sense precautions, not restrictions specific to 18k gold — they apply to any precious wire jewelry, regardless of material.

Personalizing 18k gold jewelry: words, initials, and models

Serious 18k gold jewelry offers several ways to personalize a piece, as long as you know the hand-shaping rules. The Original Personalized Bracelet remains Atelier Paulin's iconic piece, the one it all started with in 2014: a word or name hand-shaped in lowercase, except for the letter "J," which is capitalized when it starts the word. No accents or apostrophes are hand-shaped, but spaces can be added on request.

Beyond the hand-shaped word, "Initial" models carry one or more initial letters that refer to one or more names. "Capital" and "Capital Initial" models, on the other hand, are entirely in capital letters — two distinct lettering styles, chosen based on the look you want.

Some pieces accept several names at once: the Mantra Original necklace holds a short phrase or up to five names, while the Richelieu Duo necklace lets you personalize two names. Symbols remain possible on request from the atelier.

Note: a piece hand-shaped to order with the chosen word cannot be exchanged or refunded, unlike a non-personalized piece. This rule applies to all materials, including 18k gold.
