FAQ and Contact
The answer to your question can probably already be found in our FAQ.
Our Jewelry
Our jewelry is made of 316L stainless steel, a material valued for its strength, durability, and ease of care.
Depending on the model, several finishes may be offered: Gold, Rose Gold, or Silver. The materials and finishes available are always specified in the features of each product.
As a general rule, our stainless steel jewelry can be worn in contact with water, including in the shower or while washing your hands. This material is resistant to water and corrosion while maintaining its shine over time.
Important exception: jewelry containing a photo, whether visible or projected, should not be worn in contact with water. Moisture could enter the jewelry and damage the photo or the projection mechanism.
To keep your jewelry in the best possible condition for as long as possible, we also recommend avoiding chemical products, perfume, seawater, chlorinated water, and intense physical activities.
Since precautions may vary depending on the model and its customization, each product page has its own FAQ. There, you will find specific recommendations tailored to the piece of jewelry you are interested in.
Our jewelry is crafted from stainless steel, a material that does not rust, oxidize, or naturally lose its shine. However, as with all jewelry, regular maintenance is essential to preserve its brilliance over time.
Here are some simple tips to follow:
✅ Do:
- Clean your jewelry with a soft, non-abrasive cloth after wearing it.
- Store your pieces in their original box or a dry case, away from moisture and direct light.
❌ Don't:
- Let them come into contact with perfumes, household products, lotions, or any harsh chemicals.
- Wear your jewelry during intense activities, at the beach, in the pool, or in the shower, especially for designs featuring photo projections, rhinestones, or delicate stones.
What should I do if my jewelry still tarnishes?
Light tarnishing can occur over time or with prolonged exposure to moisture. In this case:
- Gently rub with a clean, dry cloth.
- If necessary, use a slightly dampened cloth without any chemical products.

Personalization
You can engrave a first name, a word, a date, or a short personal message, provided it respects the character limits specific to each piece of jewelry.
Here are some useful details:
- 🈯️ Languages: you can engrave in the language of your choice. For special scripts (e.g., Arabic), please ensure you provide the exact text to be engraved.
- 💬 Special characters: we accept the majority of symbols such as @, &, *, ♡, etc.
- ⚠️ Spaces and accents: some models, particularly those with metal cutouts, do not allow accents or spaces. For example, “Célia” will be engraved as “Celia”.
✍️ We reproduce exactly what you enter (uppercase, lowercase, symbols, etc.). It is therefore essential to check your text carefully before confirming your order.
📌 Each piece of jewelry has its own technical constraints: available space, character count, the possibility of engraving one or two sides, etc. All this information is indicated on the product page.
💡 And don’t worry: if an issue is detected with your customization, our team will contact you promptly by email to find a solution together before production.
📬 If you have any questions, our customer service team is at your disposal at elise@mon-cadeau-unique.com.
Most of our jewelry, whether necklaces or bracelets, features a standard length accompanied by an adjustable extension, for example 45 cm + 5 cm for necklaces. This allows for a comfortable fit according to your preference.
Other models are available in several fixed sizes, to be selected directly on the product page.
📌 Important:
- If no size can be selected, it means that the piece of jewelry is offered in a single, fixed length.
- Once a piece of jewelry has been personalized, it is no longer possible to modify its size or shorten it.
We recommend that you carefully check the dimensions indicated in the product description before placing your order.
