How are pearls traditionally harvested and processed in the island's pearl industry?

The cultivation and harvesting of pearls around the Balearic Islands, including Mallorca, hinge on carefully tended oyster beds along the coast near Manacor. Pearl farmers rely on natural coastal waters where the oysters can flourish, gradually layering nacre—composed of aragonite crystals bound by conchiolin proteins—around a tiny irritant introduced by hand to encourage pearl formation. This organic process can take several years and requires consistent environmental monitoring to maintain optimal water quality and oyster health.

Locally, pearl farming blends tradition with selective breeding techniques to improve both the quality and sheen of the pearls. Oysters are often suspended on ropes beneath floating platforms, mimicking natural habitats while allowing farmers to easily inspect and care for them. The skill involved in periodically opening shells to introduce new irritants and remove pearls safeguards the crop, while careful timing ensures each pearl develops its characteristic iridescence.

While the lakes and coves near Manacor provide ideal conditions, pearl farmers also employ tools adapted to the Mediterranean climate and sea temperatures, distinct from other global pearl regions. These practices have fostered a small but distinctive pearl industry, complementing Mallorca’s artisan heritage. Visitors can occasionally witness the process or learn about it at local workshops, bringing to life the island’s blend of natural beauty and human craft.
