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

Choosing 18k gold jewelry means understanding what that number actually involves: metal composition, hand-shaping, care. At Atelier Paulin, 18k gold refers to a solid wire made of 75% pure gold, also known as "the Gold of French tradition." Since 2014, the Paris workshop has hand-shaped this single length of precious wire into personalized 3D jewelry, without ever engraving or carving it. This article covers composition, available colors, real-world lead times, and care for 18k gold jewelry, so you can choose with full knowledge.

What "18k gold" means in artisan jewelry

750/1000 gold, known as 18k gold, is a solid wire made of 75% pure gold. It's what's called "the Gold of French tradition": a historic benchmark in French goldsmithing. At Atelier Paulin, every 18k gold piece is hallmarked, certified, and hand-shaped by one of the Maison's jewelry artisans, from a single length of precious wire, never assembled from several welded pieces.

The distinction matters: with 18k gold jewelry, there's no plating or outer layer involved, just a solid wire through and 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 finished, never letter by letter. This work-hardening gives the metal its shape memory and resilience.

To understand exactly what that number 750 changes in practical terms for weight, tone, and durability, our dedicated article covers every technical aspect: 18k 750 gold: 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 makes it possible to match the piece to skin tone or to jewelry already worn daily.

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

If you're torn between gold-filled and 18k gold in a rose tone, the color difference stays close to the naked eye: the real difference lies in composition and budget. To compare the two options in rose directly, the dedicated collection shows the available styles: discover 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 the intended use and budget.

In every case, each piece stays hand-shaped, never molded or mass-assembled: the wire is sculpted directly into its final form.

Hand-shaping and delivery times for an 18k gold piece

With artisan 18k gold jewelry, hand-shaping time differs from that of sterling silver or 14k gold-filled. Allow 1 to 3 working days of hand-shaping at the workshop for an 18k gold piece, compared with 24 to 48 working hours for sterling silver and 14k gold-filled. This time covers the artisan shaping the wire, forming the letters one by one, then work-hardening the entire piece.

This hand-shaping time is separate from home delivery time, which is 24 to 72 hours, shipping included. Both add up: the hand-shaped piece reaches you after these two steps.

For customers based in Paris, two options are available at the boutique itself: coming in to have the piece personalized directly at the workshop, in about thirty minutes, or having it delivered by courier the same day. It's a service few workshops offer, letting you leave with your 18k gold piece the very same day.

Every piece hand-shaped to order arrives in an individual case, with no pouch or separate certificate: the case alone serves as the piece's presentation.

Caring for an 18k gold piece 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 fine, natural, reversible tarnish on contact with air or moisture, 18k gold does not tarnish.

This stability makes it a sound choice for a piece worn every day, including through varied activities. The hand-shaped 18k gold wire also benefits from laser micro-welding reinforcement at tension points: the wire remains a single length hand-shaped throughout, with the micro-welding simply reinforcing the most stressed areas.

For the most delicate pieces, in fine wire sculpted into patterns or letters, it remains wise to avoid hard knocks and repeated handling that could distort the hand-shaped design. These are common-sense precautions, not constraints specific to 18k gold: they apply to any piece of precious wire jewelry, whatever the material.

Personalizing an 18k gold piece: words, initials, and styles

Serious 18k gold jewelry offers several ways to personalize, 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 the letter "J" in uppercase when it begins the word. No accents or apostrophes are hand-shaped, but spaces can be added on request.

Beyond the hand-shaped word, "Initial" styles carry one or more initials that stand for one or more names. "Capital" and "Capital Initial" styles, meanwhile, are entirely in uppercase: two distinct lettering styles to choose from depending on the look you want.

Some pieces accept several names at once: the original mantra necklace holds a short phrase or up to five names, while the richelieu duo necklace can be personalized with two names. Symbols remain possible on request to the workshop.

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 metals, including 18k gold.
