Pearl farms in the Philippines are located close to sustainable tourism zones. Numerous factors allow the Philippines to be a major producer of quality natural pearls; its biodiversity, cleanliness of the water and the richness of its plankton. Pearl farmers are very conscious of the fragility of the environment and have therefore become its protectors. For example, the pearl farms of the Filipino company Jewelmer (the world's second largest pearl producer) have become a national park.
This company is the largest for South sea pearls.
