If you've searched "lingotto oro" while comparing gold jewelry options, you've likely landed on a mix of bullion pricing pages and vague plating claims. This guide answers the question plainly: what is gold-filled wire (the material Italian shoppers often mean by "lingotto oro" in a jewelry context), how does it compare to solid 18k gold, and why does it matter for a piece you'll wear daily? Since 2014, Atelier Paulin has hand-shaped both materials into personalized bracelets, necklaces, and rings from its Paris workshop — here's what the numbers, the metal, and the craft actually involve.
What "Lingotto Oro" Means in Fine Jewelry — And What It Doesn't
"Lingotto oro" translates literally to "gold ingot," but in jewelry search behavior, shoppers using this term are usually trying to understand gold purity and value before buying a personalized piece — not sourcing raw bullion. The confusion is understandable: gold content terminology varies wildly between countries and sellers.
At Atelier Paulin, we work with three precious materials, and clarity here matters more than marketing language. Sterling silver 925 is an alloy of 92.5% pure silver. 14k gold-filled (or laminé 585/1000) is a solid outer layer of 585/1000 gold mechanically bonded to a brass base — not plating, not a coating. 18k gold (or 750/1000) is 75% pure gold, solid throughout, stamped and certified as French tradition gold.
None of these are ingots in the commodity sense. But the underlying question — how much actual gold is in this piece? — is exactly the right question to ask before any personalized order. We answer it with numbers, not adjectives, throughout this guide. If you're browsing with that question in mind, our full jewelry range is a good place to compare materials side by side across bracelets and necklaces.
14k Gold-Filled Wire vs. 18k Solid Gold: The Real Difference in Numbers
This is the comparison most "lingotto oro" searches are really after. Here are the exact specifications:
14k gold-filled (or laminé 585/1000): a solid outer layer of 585/1000 gold bonded under heat and pressure to a brass core. This is the legal English goldsmithing term "gold-filled" — not plating. It contains 50 to 100 times more gold than traditional gold plating, giving it the same surface properties as solid 585 gold wire. Available in yellow and rose only; there is no white gold-filled option, since white gold requires an alloy composition gold-filled bonding does not replicate.
18k solid gold (or 750/1000): a solid gold wire at 75% pure gold content, available in yellow, rose, and white. Each piece is stamped, certified, and hand-shaped by one of the Maison's goldsmith artisans.
Neither material is hollow or coated in the way mass-market "gold ingot" imagery suggests. Both are worked as a single continuous precious wire — never assembled from cast pieces or joined fragments — then hand-shaped into the final form. The choice between them is about budget and daily-wear habits, not about one being "fake" and the other "real." Our Astrology Collection shows both materials applied to the same design families, useful for a direct side-by-side.
How the Wire Becomes Jewelry: Hand-Shaping, Not Casting
A single wire of precious metal — never a cast blank, never assembled from separate fragments — is hand-shaped by a Paris artisan into its final form: a name, an initial, a word. This is the core technique that distinguishes hand-shaped wire jewelry from stamped or engraved pieces, where a motif is cut into an already-flat surface.
Once the shaping is complete, the entire piece — not letter by letter — goes through work-hardening: a cold-working process that gives the wire its shape memory and long-term resilience. This is what allows a slender gold or silver wire to hold a name in cursive script for decades without losing its form.
At tension points — where the wire curves most sharply — laser micro-welding reinforces the joints invisibly. The wire is welded, not seam-free; this reinforcement is precisely what makes a hand-shaped word durable enough for daily wear. Manufacturing time at the workshop is 1 to 3 business days for sterling silver and 14k gold-filled, and 2 to 5 business days for 18k gold — this is workshop time only, separate from home delivery, which takes 2 to 5 days including transit. For a well-shaped word or name in wire, our Bracelets collection is the widest starting point.
Caring for Gold-Filled Wire: What Changes Daily Life With It
One practical reason shoppers compare gold-filled to solid gold is maintenance — and here the two materials genuinely differ, so it's worth being precise.
14k gold-filled requires no particular care. A soft cloth from time to time is enough, and unlike traditional gold plating, it does not fear water — shower, pool, and beach are all fine. The one precaution, to preserve the delicate shape of hand-shaped wire pieces specifically, is to remove it during intense physical activity or repeated friction. Expect several decades of wear from this material.
18k solid gold follows the same low-maintenance logic: warm water, mild soap, and a soft cloth to dry.
Sterling silver 925 behaves differently — it's a "living" metal. Contact with air, humidity, or chemicals can cause a fine layer of oxidation to appear; this is natural and reversible, and never a sign of poor quality. Unlike gold-filled, silver pieces should avoid the pool, the shower, and sports.
Every piece — regardless of material — arrives in a jewelry box, ready to give or wear. If daily-wear resilience is your priority for a personalized gift, our More Love collection groups pieces designed for exactly that.
Personalization: What a Word or Initial in Wire Actually Looks Like
Once you've settled on a material, personalization is where gold-filled or 18k gold wire becomes genuinely yours. Word-based pieces are hand-shaped entirely in lowercase, with one exception: the letter "J" is shaped as a capital when it begins a word. Accents and apostrophes are not shaped, though spaces can be added on request, and symbols are possible on request as well.
Initial models work differently: one or several initial letters, referring to one or several first names — this is a distinct personalization mode from the full-word pieces above. Separately, "Capital" and "Initial Capital" models exist specifically in uppercase lettering; this is not an exception to a no-capitals rule, since capital-letter models are a standard part of the range. All lettering, in either mode, is shaped in a single cursive style.
Some pieces accommodate more than one name: the Mantra Original necklace holds a short phrase or up to five first names, while the Richelieu Duo necklace personalizes two first names. Not every piece in the catalog is personalizable — always check the specific product before assuming. Ring sizes for personalizable models run from 48 to 62.

Questions fréquentes
Is 14k gold-filled the same as gold plating?
No. Gold plating is a microscopically thin coating that wears off over months. 14k gold-filled is a solid outer layer of 585/1000 gold mechanically bonded under heat and pressure to a brass core, containing 50 to 100 times more gold than traditional plating. It behaves like solid 585 gold on the surface — including resistance to water — and lasts several decades with normal wear.
Can I shower or swim with gold-filled jewelry?
Yes. Unlike gold plating, 14k gold-filled does not fear water — shower, pool, and beach are all fine. The only precaution, to protect the delicate shape of hand-shaped wire pieces, is removing it during intense physical activity or repeated friction. Sterling silver, by contrast, should avoid water exposure since it's a more reactive metal.
What's the difference between gold-filled and 18k solid gold?
Gold-filled (14k) is a solid gold layer bonded to a brass base, available in yellow and rose. 18k solid gold is 75% pure gold throughout, stamped and certified, available in yellow, rose, and white. Both are worked from a single precious wire and hand-shaped, not cast — the difference is gold content, price point, and that white is only available in 18k.
How long does it take to make a personalized gold-filled piece?
Workshop shaping time is 1 to 3 business days for sterling silver and 14k gold-filled, or 2 to 5 business days for 18k gold — this covers time at the atelier only. Home delivery takes an additional 2 to 5 days including transit. In Paris, you can also have a piece personalized on-site in about thirty minutes, or receive same-day courier delivery.
Can I return a personalized gold-filled bracelet if I change my mind?
A non-personalized piece can be refunded or exchanged. However, a piece hand-shaped to order with a chosen word or name cannot be exchanged or refunded, since it's made specifically for that request. This applies regardless of material — gold-filled, sterling silver, or 18k gold.
