The house that cultured the golden South Sea pearl, and turned Philippine waters into a wellspring of fine jewelry.
Shop JewelmerJewelmer didn't just create a luxury brand. It created the gem. The golden South Sea pearl exists as a commercial object because Jewelmer spent a decade in Palawan waters figuring out how to grow one.

Forty-Five Years of Patience, Palawan, and Pearls
In 1979, a French pearl farmer and a Filipino entrepreneur set up a small experimental farm in Palawan, in the southernmost waters of the Philippine archipelago. They worked alongside the Badjao — a sea-faring ethnic community who had dived these waters for generations — harvesting oysters from the Sulu Islands and grafting them under the guidance of Japanese pearl specialists. What they were attempting had never been done at scale: the cultivation of the golden South Sea pearl, the rarest color variation of Pinctada maxima, the world's largest pearl-producing oyster.
You can read the story of the sea on the surface of a pearl. As an indicator of the health of the planet, the pearl can only thrive in pristine waters.
After a decade of harvests yielding white and silver pearls, 1989 brought the breakthrough: the first truly golden South Sea pearls, cultured in Palawan's pristine waters. The following year, Jewelmer showed its jewelry alongside Cartier and Mikimoto at an exhibition in Monaco, drawing admiration from Prince Rainier III. By 1996, Philippine President Fidel V. Ramos had declared the golden South Sea pearl the country's National Gem — and placed it on the one-thousand peso note.
Today, Jewelmer's craftsmen work in ateliers in both France and the Philippines, trained in the haute joaillerie techniques of Paris's Place Vendôme. Each piece is built around pearls left exactly as nature made them — no artificial enhancement, no color treatment. In 2006, the brand founded the Save Palawan Seas Foundation, turning its pearl farms into conservation infrastructure: organic farming programs, coastal cleanups, medical missions for coastal communities. Pearl farming, Jewelmer has long argued, is one of the few economic activities that enriches the environment instead of diminishing it.

What Makes Jewelmer Different
01
They Created the Gem
The golden South Sea pearl is not a material Jewelmer found and fashioned. It is a material Jewelmer spent ten years learning to cultivate. The brand's entire existence rests on a decade of patience and scientific research in Palawan, and the result was declared the Philippines' National Gem.
02
Conservation Is the Business Model
Pearl oysters can only thrive in clean water. That fact turns Jewelmer's commercial interests and its environmental ones into the same interest. The Save Palawan Seas Foundation, founded in 2006, extends that logic to the wider community, providing sustainable livelihoods and protecting the seas that make the whole enterprise possible.
03
Filipino Luxury on the World Stage
Jewelmer has shown alongside Cartier and Mikimoto in Monaco, dressed Miss Universe Philippines, and opened a flagship on Worth Avenue in Palm Beach. Its craftsmen are trained in Place Vendôme techniques.
