Our Materials & Expertise

Transparency above all. Gold, silver, and nothing else.
At Opaline Paris , we firmly believe that jewelry is an emotional object that should last. That's why we've banned brass, steel, and base metals from our workshops. We work exclusively with precious metals.
1. The Soul of the Jewel: Solid Silver S925
It all starts with the base. No copper, no unknown metals. All our creations are crafted from a 925 Sterling Silver base.
- Why? It is a noble, precious metal and naturally hypoallergenic.
- The guarantee: You will find the maker's mark or the "925" hallmark on each of our pieces, guaranteeing their authenticity.
- For you: The assurance of wearing a healthy piece of jewelry that respects your skin and will not cause allergies (0% Nickel, 0% Lead, 0% Cadmium).
2. The Brilliance: 3 Micron Gold Plating
To adorn this silver, we do not simply "gild". We apply a layer of 18-carat gold with a thickness of 3 microns .
- The standard: This thickness corresponds to the French legal designation of "Gold Plated" and to the "Vermeil" standard in the United States.
- The finish: We worked with a soft and luminous shade of gold, neither too yellow nor too red, for a chic and timeless look.
- Durability: Thanks to its generous thickness, your jewelry withstands daily life much longer than classic gold plating.

Our Quality Commitments
- Hypoallergenic : Absolutely respectful of sensitive skin.
- 1-year warranty: Because we believe in the quality of our plating.
- Certified: Precious metals that are inspected and hallmarked.
Our Stones: Uncompromising Radiance

At Opaline Paris , we believe a piece of jewelry should shine. Not just on the first day, but for a long time. That's why, just as with our metals, we've banned low-grade crystals and glass.
We have selected two types of exceptional stones to accompany our Silver and Gold settings: 5A Zirconium for our timeless pieces, and Moissanite for our prestige pieces.
1. 5A Zirconium: Everyday "Diamond" Brilliance
(Featured in our 3-micron gold-plated collection)
Think all rhinestones are created equal? Think again. Zirconium oxide (or zirconia) is graded on a quality scale from A to 5A.
- A or AAA: What you usually find in classic costume jewelry. Shiny, but lacks depth.
- 5A Quality (The Opaline Choice): This is the top of the pyramid. Our stones are hand-cut with the same facets as a genuine diamond (Brilliant cut).
- The result: Pure clarity, intense light refraction, and exceptional durability. To the naked eye, it is almost impossible to distinguish it from a diamond.
2. Moissanite: Born of the Stars
(Coming soon to our Gold Filled Prestige collection)
For our upcoming exceptional collection, we wanted to go even further. We chose Moissanite , a fascinating stone with a unique history.
- Origin: Initially discovered in a meteorite, Moissanite is now recreated in the laboratory for perfect purity and impeccable ethics (0 conflict, unlike some diamonds).
- Brighter than diamond: It's scientific. Moissanite's refractive index (2.65) is higher than that of diamond (2.42). It reflects more light and offers spectacular rainbow "fires".
- Scratch-resistant (or almost): On the Mohs hardness scale, diamond is 10. Moissanite is 9.25. It is the second hardest gemstone in the world after diamond. It will never scratch and will retain its brilliance forever.
- The ultimate test: Moissanite is so close to diamond that it often fools jewelers' thermal testers!
Comparative Chart: Understanding What You Wear
To help you choose, here's how our stones compare to the rest of the market:
| Stone Type | Hardness (Strength) | Brightness (Refraction) | Ethics | Budget |
| Crystal / Glass (Basic Fantasy) | Weak (scratches easily) | Weak | - | € |
| Zirconium 5A (Classic Opaline) | Strong (8.5/10) | Excellent (Close to Diamond) | 100% Lab | €€ |
| Moissanite (Prestige Opaline) | Extreme (9.25/10) | Superior to Diamond | 100% Lab | €€€ |
| Natural Diamond | Absolute (10/10) | Reference | Variable | €€€€€ |
Our Ethical Commitment
By choosing 5A Zirconium and Moissanite, Opaline Paris is committed to responsible beauty. Our stones are lab-grown. This means:
- No polluting mining.
- No conflict zones.
- Full traceability and a reduced carbon footprint.
Shine with full awareness.

Size guide

Afraid of making a mistake? Don't panic.
At Opaline Paris, we want your jewelry to fit you like a second skin. Follow our simple tips to choose the perfect size.
1. The Rings
This is the most delicate measurement. To find out your size, we offer two methods.
Method 1: Measure one of your rings (Most reliable)
If you already have a ring that fits you well on the desired finger:
- Place the ring on a flat surface.
- Measure the inside diameter of the ring (without taking the metal into account) using a millimeter ruler.
- Refer to the table below.
Method 2: Measure your finger circumference
If you don't have a ring handy:
- Take a piece of string or a strip of paper.
- Wrap it around the base of your finger (without squeezing too tightly).
- Mark the meeting point with a pen.
- Measure the resulting length (circumference) in millimeters.
Correspondence Table
| French size (Your size) | Inner Diameter (mm) | Finger circumference (mm) |
| 50 | 15.9 mm | 50 mm |
| 52 | 16.5 mm | 52 mm |
| 54 | 17.2 mm | 54 mm |
| 56 | 17.8 mm | 56 mm |
| 58 | 18.5 mm | 58 mm |
| 60 | 19.1 mm | 60 mm |
-> Opaline's tip: If you're hesitating between two sizes, always choose the larger size . Fingers tend to swell slightly in the heat or at the end of the day.

2. The Necklaces
To help you visualize how our chains will hang, here are the standard lengths:
- 38-40 cm (Choker): Worn at the base of the neck. Ideal for accentuating the way you hold your head.
- 45 cm (Standard): The "classic" length which reaches the collarbones. It is suitable for all necklines.
- 50-55 cm (Matinee): Falls above the chest. Perfect for layering with a shorter necklace.
Note: Most of our necklaces have a 3-5cm extension chain to adjust the length to your liking.

3. The Bracelets
Our bracelets are designed to fit most wrists.
- Standard Size: Our bangles and chains generally measure between 15cm and 16cm , with an extension allowing them to go up to 18 or 19cm .
-
How to measure? Use a flexible measuring tape to measure your wrist just past the bone.
- Add 1 cm for a "fitted" fit.
- Add 2 cm for a "loose" fit.
