South Sea
Heart-Shaped
Golden Pearl
An Invitation to the Miracle of the Golden Sea
The world's rarest South Sea Golden pearl — once in a lifetime. Cultivated in the Sulu Sea, Philippines. Presented exclusively in Thailand by Femme Fatale Pearl Bar Jewelry in partnership with Nagahori Pearl Corporation, Tokyo.
The Origin Story
The Sanctuary of
the Sulu Sea
Introducing a true miracle of fine jewelry — the world's first gold-colour, heart-shaped South Sea cultured pearl. A harmonious and breathtaking blend of nature's unpredictability and masterful human artistry, brought to life for the very first time.
Cultivated in the pristine, nutrient-rich waters of the Sulu Sea, Philippines, this tranquil haven serves as an exclusive sanctuary where nature is left undisturbed to perform its quiet, golden miracles.
One farm. One pearl variety. One miracle — available in Thailand only through Femme Fatale Pearl Bar Jewelry.
The Artisan's Challenge
The Privilege
of Rarity
The perfect silhouette is not coincidence. It begins with a meticulously handmade heart-shaped nucleus. Navigating the precise angle of the heart's cleft within a living organism is an immense technical challenge — the culmination of grueling maritime trial, error, and unwavering dedication.
The creation of this shape demands only the most superior mother oysters — those yielding perfectly round pearls over 14mm in their very first harvest. This elite selection represents a mere fraction of a percent of all oysters.
Because the yield is naturally limited, mass production is simply impossible. Each piece is an extraordinarily rare gift from the sea.
While shaped freshwater pearls exist, their thin nacre inevitably reveals the flat artificial core beneath — limiting their depth, weight, and luminosity.
The Heart Collection boasts the rich, profound nacre thickness exclusive to South Sea pearls — producing magnificent volume, weight, and deep inner luminosity that places it at the highest echelon of fine jewelry.
The result: magnificent volume, weight, and deep inner luminosity that firmly places the Nagahori Heart at the highest echelon of fine jewelry.

How the partnership began
Bangkok Jewelry Fair,
April 2025
Our founder Eimjung walked into the Bangkok Jewelry & Gem Fair having just returned from Guangzhou — her first real encounter with the pearl world. She found the Nagahori booth and sat down.
She sat there for almost an hour. Mark and Mace from Nagahori Japan answered every question she had. They let her touch pearls she had never held before — Akoya, South Sea, and then the heart pearl.
That was the moment everything changed. Before she left, she said it plainly: "I'm going to build a pearl business and I'm going to do it with you."
Two months later she was GIA Graduate Pearls certified With Honors. The partnership was formalised. Femme Fatale became the only retailer in Thailand with access to the Nagahori Heart collection.
"I looked at them and said — I'm going to do business with you. Two months later — GIA certified. First Birth of Pearl workshop. A dream becoming real."

April 2025. Bangkok Jewelry & Gem Fair. Eimjung sat at their booth for almost an hour — asking everything, touching pearls she had never seen before. They were patient, generous, and genuine. By the end of that conversation, a partnership was born.
One year later, Mark and Mace flew to Bangkok to stand beside Eimjung at the Grand Opening of Femme Fatale Pearl Bar — the boutique that began with that conversation. This photograph was taken that evening.
"I looked at them and said — I'm going to do business with you. And I meant every word."
