How to Authenticate Hermès Mosaique au 24 Platinum: 5 Signs to Check
The Hermès Mosaique au 24 Platinum collection is one of the house’s most recognizable tableware designs. Inspired by the iconic mosaic floors of the historic Hermès boutique at 24 Faubourg Saint-Honoré in Paris, the collection combines geometric patterns with hand-applied platinum details.
As interest in Hermès Home continues to grow, more pieces are appearing on the secondary market. Based on multiple authentic Mosaique au 24 Platinum pieces personally handled and photographed by Bagotica, here are several details worth checking when authenticating your piece.
1. Study the Mosaic “H” Logo
The Placement of the Dark Mosaic Tiles Inside the “H”
At first glance, the central “H” appears perfectly symmetrical. However, authentic Hermès Mosaique au 24 Platinum pieces feature a very specific and intentionally asymmetrical placement of the darker mosaic tiles.
The darker tiles inside the “H” do not follow a mirrored pattern. Their placement is consistent across authentic pieces and can serve as a useful authentication detail.
On the left vertical bar, the dark tiles create an irregular sequence. One dark tile appears near the upper section, another is positioned in the center of the bar, and a third is located lower and slightly toward the outer edge.
On the right vertical bar, the arrangement is different. A dark tile sits directly below the upper horizontal section, another appears one tile below the center line, and a third is positioned near the lower outer corner.
Because this arrangement is intentionally asymmetrical, counterfeit pieces often fail to reproduce it correctly. Fakes frequently place the dark tiles symmetrically, randomly, or in completely different positions.
2. Look for Small Production Marks
Some authentic Mosaique au 24 Platinum pieces feature tiny production marks, workshop symbols, or impressed codes positioned beneath the backstamp on the underside of the piece.
On authentic pieces, these small marks are usually positioned directly beneath the Hermès backstamp, centered with the logo and located very close to the outer rim of the plate, cup, or bowl.
These markings can appear as stars, snowflake-like motifs, geometric symbols, workshop signs, or impressed number codes. Because they are extremely small and discreet, they can easily be overlooked without careful inspection.
The examples below have been enlarged for easier identification.
Their presence can support authenticity, although the absence of such marks alone does not automatically indicate a counterfeit. As with Hermès handbags, authentication should never rely on one single detail. Production marks should always be considered together with the logo, porcelain quality, decoration, and original packaging.
Enlarged examples of authentic Hermès Mosaique au 24 Platinum production marks found directly beneath the backstamp and near the outer rim of the porcelain piece.
Because the mark is so small, many collectors overlook it entirely. However, when authenticating Mosaique au 24 Platinum pieces, this tiny symbol deserves attention, as genuine examples from the collection consistently feature a production mark near the rim beneath the backstamp.

3. Examine the Packaging and Protective Foam
Original Hermès Mosaique au 24 Platinum pieces are presented in signature orange boxes with high-density white protective foam inserts specifically designed for each item.
The foam itself can be a useful authenticity indicator. Authentic Hermès packaging uses dense, bright white, closed-cell foam with a fine and uniform texture. Counterfeit sets often include foam that appears slightly bluish, grey, or yellowish and usually has larger, coarser bubbles and a cheaper appearance.
The precision of the foam cut-outs is equally important. Authentic inserts are custom-shaped for every piece and feature clean, sharp, and perfectly symmetrical openings. Saucers, plates, cups, and mugs sit securely inside dedicated recesses rather than simple generic slots.
For example, cup compartments include precisely rounded finger openings that make removing the cup easy and safe. Plate and saucer sections feature carefully carved circular cut-outs that follow the exact shape of the porcelain.
Counterfeit packaging frequently overlooks these details. The foam inserts may have rough edges, oversized openings, poorly finished cut-outs, or generic rectangular slots that do not perfectly match the shape of the pieces.
Because Hermès pays exceptional attention even to its packaging, the protective foam itself can provide valuable clues when evaluating the authenticity of a Mosaique au 24 Platinum set.
4. Check the Original Box Reference Codes
During our examination of multiple authentic Mosaique au 24 Platinum pieces, we observed the following original box references:
| Product Type | Diameter / Set | Observed Original Box Code |
|---|---|---|
| Single Tea Mug | — | 1345 |
| Dessert Plate | 21 cm | 1338 |
| Dinner Plate | 27.5 cm | 1336 |
| Dessert Bowl | — | 1341 |
| Coffee Set for Two (2 cups + 2 saucers) | — | 1344 bis |
| Tea Set for Two (2 cups + 2 saucers) | — | 1343 bis |
| Cake Plate | 32 cm | 1148 quater |
These observations are based on authentic pieces that passed through our hands and may help collectors compare their packaging.
However, box references should only be considered supporting indicators.
Hermès may update packaging references over time, and original boxes can occasionally be replaced or lost.
5. Study the Hidden Micro HERMÈS Signatures
Another detail that is frequently overlooked is the tiny HERMÈS signature hidden inside the mosaic decoration.
On coffee and tea saucers, the micro signature is integrated into the final row of mosaic tiles and sits precisely on the vertical centerline beneath the central logo.
Large tea mugs without saucers follow a different rule. The HERMÈS inscription is placed in the last row of tiles but is intentionally shifted slightly to the right rather than being perfectly centered.
Decorated plates also feature a hidden HERMÈS signature within the mosaic border. On double-sided plates, the signature appears on the reverse side and aligns exactly with the vertical axis running through the center of the main logo.
These inscriptions are extremely small and blend naturally into the mosaic design. Most owners never notice them, and even experienced resellers and collectors often overlook them. Once you know where to look, however, the hidden HERMÈS signature becomes one of the most fascinating authentication details of the Mosaique au 24 Platinum collection.
Final Thoughts
The Hermès Mosaique au 24 Platinum collection is beautifully crafted and highly collectible. As interest in Hermès Home continues to grow, understanding the small details that distinguish authentic pieces becomes increasingly important.
Because counterfeiters continue to improve, documenting these subtle details has become increasingly important for collectors and buyers.
The observations in this guide are based on multiple authentic Mosaique au 24 Platinum pieces personally handled and photographed by Bagotica and are intended as educational information for collectors and buyers.
When in doubt, always evaluate several authentication points together. No single detail should ever be used to determine authenticity.
