A HEWREN brooch is not assembled from mass-produced components. It grows from a single unrepeatable stone over several days through the hands of a master silversmith. There is no factory assembly line, no cold machine-stamping, and no standardized part that snaps into place. Following our "Let Nature Lead" philosophy, every creation begins the exact same way: a raw, natural specimen arrives on the wooden workbench, and an artistic dialogue begins.
The journey takes between three and seven business days for an individual made-to-order piece. Some of that time is active sculptural work — hand-carving in green jeweler wax, casting in solid S925 sterling silver, oxidization, and custom stone setting. Some of it is deliberate patience: waiting for investment plaster to cure, for molten silver to crystallize, and for hand polishes to settle. Neither kind of time can ever be rushed.
At a Glance: The HEWREN Brooch Craft
- Primary Materials: Untreated baroque freshwater pearls, natural Baltic amber, and solid S925 sterling silver
- Core Technique: Traditional hand-carved wax modeling and lost-wax casting (cire perdue)
- Production Time: 3–7 business days per individual piece
- Signature Engineering: Concealed 2-in-1 pendant bail and custom-contoured bezel settings
Step 1 — The Stone Arrives & Observation (Day 1)
Each specimen arrives at the studio individually wrapped. It is not yet a piece of jewelry — it is a raw, organic baroque pearl, a rough piece of amber, or a labradorite with an uneven edge. The first action is not sketching, but careful observation. The stone is turned in the hand, studied against natural window light, and examined from every dimensional angle.
We analyze its shape (elongated, teardrop, or folded), its optical behavior (how nacre orient or amber warmth refracts), and its surface texture. These organic nuances become the creative constraints of the piece. The stone is never cut or ground down to fit a standardized setting; rather, the silver sculpture is hand-built around the stone.
Step 2 — Organic Conception & Design (Day 1–2)
With the stone's natural silhouette understood, the concept begins to resolve. Often the biological form is immediate — an asymmetrical curved pearl suggests the body of a curled animal, while a flatter specimen suggests a hummingbird's wings. Sketches are penciled directly around the stone's physical contours. If a pearl is subtly lopsided, the framework follows that asymmetry with purpose.
Step 3 — Hand-Carving the Wax Model (Day 2–3)
This is where the wearable sculpture first assumes three-dimensional life. A block of dense green jeweler wax is hand-carved into the exact anatomical shape of the design. The artisan uses micro-gravers for delicate feather and fur textures, paired with rotary burs for anatomical volume. Every feather on a bird's wing and every contour on an animal's limb is carved by hand. A custom seat is carved into the wax to mirror the exact millimeter contours of the chosen gemstone.
Step 4 — Lost-Wax Casting (Day 3–4)
The completed wax sculpture is sprued and encased in a steel flask filled with liquid investment plaster. After the mold solidifies, the flask is placed into a burnout kiln. The wax melts and evaporates completely, leaving a hollow cavity that preserves every microscopic carving stroke. Molten S925 sterling silver is vacuum-cast into the flask at over 960°C. Once cooled, the plaster is washed away to reveal the raw solid silver casting.
Step 5 — Hand-Finishing & Custom Stone Setting (Day 4–5)
The raw silver casting requires extensive hand-refinement. Casting sprues are sawn off, seams are burnished, and surfaces are smoothed through multiple grades of abrasive paper. Recessed crevices (such as feather valleys or eye contours) are oxidized to create deep dramatic shadow, while high ridges are buffed back to a mirror shine. Finally, the stone is mounted. For organic baroque pearls, this involves hand-burnishing a custom silver bezel or setting prongs over the pearl's irregular contour.
Step 6 — Final Polish, Quality Inspection & 2-in-1 Hardware Check (Day 5–6)
The completed piece undergoes rigorous quality control. The reverse pin stem is tested for smooth tension, the rotary safety catch is inspected for secure closure, and the hidden pendant bail is verified to fit chains up to 3mm. The piece is cleaned in an ultrasonic bath, hand-buffed with jeweler rouge, and prepared for dispatch.

| 1. Stone Selection | Examining natural contour, luster, and optical behaviors | Day 1 |
| 2. Concept & Sketching | Composing anatomical lines directly around the raw gem | Day 1–2 |
| 3. Hand Wax Carving | Carving full anatomical volume and hair-line textures in jeweler wax | Day 2–3 |
| 4. Lost-Wax Casting | Kiln burnout and vacuum casting with molten S925 sterling silver | Day 3–4 |
| 5. Finishing & Setting | Surface smoothing, selective oxidization, and custom bezel burnishing | Day 4–5 |
| 6. Final Polish & QA | Hardware tension testing, ultrasonic cleaning, and final luster check | Day 5–6 |
Frequently Asked Questions
Is every HEWREN piece really carved by hand from wax?
Yes. The master model for every design in our collection begins as a hand-carved block of jeweler's wax. The intricate feather textures, animal contours, and tailored gemstone seats are sculpted entirely by hand before undergoing lost-wax casting.
What is lost-wax casting (cire perdue)?
Lost-wax casting is an ancient metallurgical art form dating back over 5,000 years. A hand-carved wax model is encased in liquid plaster; when baked in a high-temperature kiln, the wax melts away, leaving a cavity. Molten sterling silver is poured into this cavity, reproducing every subtle carving detail in solid precious metal.
Does HEWREN use 3D printing in production?
While digital CAD tools may be referenced for technical proportion planning, our signature textural detailing, wax carving, stone seating, oxidization, and final mirror-polishing are performed entirely by human hands at the jeweler's bench.
Why will my piece look subtly different from the website photographs?
Because we work exclusively with genuine, untreated organic gems like baroque pearls and natural Baltic amber, no two stones in nature are identical. Your piece will share the exact design theme, metal weight, and craftsmanship standards as the catalog item, but its gemstone contours, rainbow orient, and natural growth lines will be completely unique to you.
