Let's create together the one that will tell your story in beauty. You will live an experience of pure creation by surrounding yourself with our listening and our know-how.

The golden rule of our creative workshop: exclusivity. Each piece of jewelry is designed for you, only for you.

1. Discussion & Project Definition

It all starts with a personalized consultation, by email, phone, or in person. You explain your idea to us:

• Type of jewelry (ring, wedding band, pendant, bracelet, etc.)
• Desired style (classic, modern, vintage, minimalist, etc.)
• Center stone (diamond, sapphire, emerald, etc.)
• Estimated budget

You can send us inspirational photos, sketches, or existing examples. This initial discussion allows us to understand the emotion you wish to convey with this piece of jewelry. Even a vague idea is enough: we help you transform it into a concrete piece.

2. Jewelry Expertise & Personalized Quote

Our experts advise you on:

• The selection of precious stones and certified diamonds
• The metals (white gold, yellow gold, rose gold, platinum)
• The settings and finishes

We then provide you with a detailed, free, clear, and no-obligation quote.

3. Order with secure payment and guaranteed delivery.

After you approve the quote, we will send you a link to place your order online with secure online payment and guaranteed delivery covering 100% of the jewelry's value.

• Payment options include credit card (Visa, Mastercard, American Express), 3-installment payment plan (no fees), PayPal, or bank transfer.
• Delivery is via registered mail or private courier (Chronopost, etc.). Personal delivery is available upon request.

4. 3D Modeling of the Jewelry and Technical Drawing

After order confirmation, your jewelry takes shape through a technical drawing with four views and all the dimensions needed to visualize the piece and specify the technical details.

This step allows you to approve the shapes, volumes, and proportions of the jewelry before manufacturing.

Please note that this is a technical drawing before casting, shaping, and setting:

• The prongs are not yet refined and flattened, which is done during setting.
• The angles are sharp because they have not yet been rounded and smoothed, which is done during shaping.

5. Adjustments & Final Approval

Based on your feedback, we make the necessary adjustments to the technical drawing:

• modification of the stone setting height
• modification of the curves, heights, and widths of the jewelry design
• change of the engraving, gold color, etc.

In addition to the technical drawing, we can also provide the following upon your request:

• a wax model or casting of the jewelry to give you a precise idea of ​​its volume.
• a realistic 3D rendering allowing you to approve the aesthetics of the jewelry.

We only proceed with manufacturing after your complete approval.

6. Handcrafted Jewelry

Once the technical design is approved, your piece of jewelry is handcrafted by our artisan jewelers.

The eye, hand, and heart of the artisan jeweler are the cornerstones of the quality and soul of your jewelry.

Each piece goes through several stages: casting, assembly, stone setting, polishing, and final quality control.

The jewelry is 100% made in France.

⏱️ Total time required to create a custom design:

4 to 8 weeks, depending on the complexity of the project

For a bespoke creation, the production time often depends on the chosen design and the time required for each step. From shaping to setting and finishing, the piece requires careful craftsmanship, which explains why it is not available immediately. Once completed, shipping must also be secure to avoid any issues during transit. Discreet packaging, tracked delivery, and signature upon receipt are all details that provide real peace of mind.

The advantages of a custom-made creation

• A 100% unique piece of jewelry, created exclusively for you
• Personalized guidance from expert jewelers
• Choice of materials: 18-karat gold, platinum, diamonds, and precious stones
• A creation tailored to your budget and desires
• Before manufacturing, a technical drawing is created to validate the volumes, shapes, and dimensions.
• The jewelry is then previewed in 3D rendering before production.
• Handcrafted with respect for jewelry-making traditions

A bespoke creation is ideal for celebrating a special moment:
💍 engagement – ​​💒 wedding – 🎁 anniversary – ❤️ birth – 🌟 symbolic jewelry

Advanced customization of the setting allows you to go far beyond a simple choice of model. You can adjust the shape of the setting, the proportions, the height of the prongs, and the finishes to achieve a perfectly balanced result. These subtle refinements greatly impact the final piece, influencing both its aesthetics, comfort, and the way the stone is showcased. A discreet engraving or a slight design adjustment can also make the creation more personal without altering its essence. It is often this level of detail that gives a ring its truly unique character.

What is the price of a custom-made piece of jewelry?

Following our initial discussions and a clear understanding of the piece you wish to create, we will send you a detailed quote. The price includes all the specifications discussed together. The quote will also include a link from which you can place your custom order online, with payment in full or in 3 interest-free installments.

Can I create a piece of jewelry remotely?

Yes, the entire process can be done remotely: communication (via email, phone, or video call), technical drawings and 3D renderings for design, modifications, and then approval of the design before production, selection of engravings and special finishes, selection of stones with presentation of quality certificates, and secure and insured payment and delivery methods. We have been creating custom-made jewelry remotely for individuals for 20 years. Our clients are particularly satisfied, as evidenced by the i-diamants reviews on the globally recognized platform Trustpilot.

How long does it take to create a custom piece of jewelry?

On average, between 4 and 8 weeks from the order date, depending on the complexity of the project. We are very strict about respecting the deadlines announced at the beginning of the project. We are well aware that meeting the delivery date is crucial, especially for engagements, weddings, anniversaries, births, etc.

Can I incorporate stones or materials that I already own?

Yes, we can use your stones and/or your gold, subject to prior verification by our team and confirmation that they are suitable for the requirements of your jewelry project (quality and dimensions of the stones, quality and purity of the gold, etc.). Note that we work exclusively with 18 carat gold (750/000) and/or 950/000 platinum.

Why does certification truly provide reassurance when choosing a diamond?

When creating a bespoke piece of jewelry, a diamond certificate immediately brings greater confidence. It details the stone’s characteristics, such as its weight, color, and clarity, and helps verify that the diamond matches what was promised. Recognized laboratories also play an important role, as they assess the stone independently. In addition, a thorough quality check is carried out before the jewelry is made, ensuring the diamond has been carefully selected and is perfectly suited to the final creation.
