Drilling a Tahitian pearl is a delicate operation that requires great precision.
Each pearl is unique in its shape: an error of just half a millimeter can break the harmony of the final setting.
This meticulous work combines technique, craftsmanship, and aesthetic sense.
1. Selecting the pearl
Before any intervention, the pearl is carefully examined.
I determine its shape, diameter, symmetry, the position of possible imperfections, and its most beautiful reflections.
Depending on its future use — pendant, earrings, ring, or bracelet — I determine the type of drilling to perform: single or through-hole.
Each piece of jewelry requires a different technique.
2. Marking the drilling point
The next step consists of marking the exact location of the hole.
This step is crucial: it must be perfectly centered to ensure visual balance and a stable setting for the jewel.
3. Fixing the pearl
The pearl is then securely held in a suitable support, often made of rubber, to avoid any vibration.
The goal is to guarantee absolute stability during drilling.
This support protects the nacre from micro-cracks and ensures the perfect positioning of the hole.
4. Choosing the drill and bit
Drilling is performed with a special drill equipped with a stainless steel bit shaped like a beveled knife.
The diameter generally ranges from 0.6 mm to 1.2 mm.
For larger holes, it is preferable to start with a pilot hole and gradually reach the desired diameter.
5. Cleaning and inspection
Once the drilling is complete, the pearl is cleaned to remove any trace of nacre dust.
It is then inspected to verify the regularity of the hole.
If necessary, the edges of the hole are slightly polished.
6. Double drilling
Some pearls intended for bracelets or necklaces require double drilling.
In this case, the two entry points must be perfectly aligned.
Drills designed for pearls are equipped with a gimbal that allows the pearl to rotate and be drilled at the exact opposite point.
It is impossible to achieve a satisfactory result without this device.
This type of drilling requires even greater precision.
7. Finishing and mounting
Finally, the drilled pearl is ready to be mounted on a piece of jewelry.
It can be attached to a gold, silver, or steel pin, glued or screwed depending on the setting type.
Each jeweler adapts the method according to the pearl's shape and the desired design.
Once mounted, the pearl reveals all its brilliance and harmony, ready to be worn as a symbol of Polynesian elegance.
Conclusion
Drilling a Tahitian pearl is an art in itself, the result of long experience and extreme precision.
From selection to setting, every step requires patience and respect for the materials.
Behind every jewel lies a mastered gesture that perfectly enhances each pearl.
