Discover How Pearls Are Farmed in Thailand
Pearls are the only gems made by a living creature, and few people get to see how that actually happens. If you’ve ever wondered how are pearls farmed in Thailand, the answer lives just off the coast of Phuket, where Amorn Phuket Pearl has been quietly cultivating the country’s finest cultured pearls for more than 50 years.
Across three generations of family-run expertise, our floating farm in Sapam Bay turns a small implanted nucleus into a lustrous pearl over months of careful work. This page walks you through the full process, the pearl varieties we produce, the sustainability practices behind them, and how visitors of all ages can see it firsthand.
The local fishermen search for the oyster pearl by diving around the ocean floor before retrieve the oysters from the sea. Phuket pearl’s farm then collects the oysters from fishermen.
After the recuperation is done, each oyster is to be sorting into 3 groups.
Group 1: The good breeder pearl oysters which are to be use for future breeders.
Groups 2: The healthy pearl oysters which have the perfect shell, ready for implanting nuclei on both shells.
Groups 3: The healthy pearl oysters with some incomplete structure which would then be implanting a single nucleus on one side of the shell.
Each nucleus is implanted into the pearl oysters, which nucleus’s size is depending on the size of each oyster to be received.
After the implantation process, the oysters are to be transfer to another recuperating zone to receive the extra care from the staffs to ensure the health due to the implantation is risky for the oyster. During this period, the staffs are closely monitored every oyster for approximately 30 days.
The healthy oysters with nucleus are drilling on its shell which is outside the oyster body so that no harm is to come to the oysters. Then the pearl oysters are to be strung in a row hanging from the wooden rafts frame that floating on top of the sea while the oysters are peacefully culturing beneath the sea surface.
During the culturing period, the pearl oysters are frequently clean to remove the oyster’s natural enemy that comes to attach itself to the shell which could kill the oysters.
In approximately around 10 to 24 months, the pearls would be ready for harvesting. These pearls are to be transfer to Phuket Pearl’s factory for sorting each oyster into 3 different kind of raw product of: loose pearl, pearl on the shell and pearl oyster’s shell.
The pearls are then sending to the manufacturing procedures which consist of:
1. Pearl separation according to the quality assessment of Phuket Pearl Group Company for quality control.
2. The manufacturing process to craft into the pearl jewelry by Phuket Pearl’s factory.
3. The assembly process is to attach the selected pearls with the setting.
How Pearls Are Farmed in Thailand (Step-by-Step)
The full cycle of how are pearls farmed in Thailand takes anywhere from 10 months to four years, depending on the pearl type. Here is the process we follow at Amorn Phuket Pearl, broken into five clear stages.
Step 1: Farm Preparation and Oyster Collection
Local fishermen dive along the ocean floor to retrieve pearl oysters from the sea. Phuket Pearl’s farm then collects the oysters from the fishermen and transfers them to the floating farm. Here, the oysters rest in a dedicated recuperation area before any work begins.
Step 2: Sorting the Oysters
After recuperation, each oyster is sorted into one of three groups:
- Group 1: Healthy breeder oysters set aside for future breeding
- Group 2: Healthy oysters with perfect shells, ready for nucleus implantation on both sides
- Group 3: Healthy oysters with some structural imperfections, suitable for single-side implantation
Step 3: Nucleus Implantation
Each nucleus is carefully inserted into the oyster, with the nucleus size matched to the size of the host oyster. This stage is the most delicate part of the process, as a poorly handled oyster can be lost entirely.
After implantation, oysters are moved to a separate recuperating zone where staff monitor them closely for approximately 30 days to make sure they recover well.
Step 4: Culturing in Sapam Bay
The healthy implanted oysters have a small hole drilled through the outer edge of the shell (away from the oyster’s body) so they can be strung in rows. These rows hang from wooden raft frames floating at the surface, while the oysters themselves cultivate quietly beneath the sea.
Throughout the culturing period, oysters are cleaned regularly to remove natural predators that would otherwise attach to the shell and kill the host.
Step 5: Harvesting and Grading
After roughly 10 to 24 months, the pearls are ready for harvest. Oysters are collected and brought to the Phuket Pearl factory, where they are sorted into three categories: loose pearls, pearls still on the shell, and the pearl oyster shells themselves.
From there, pearls move into the manufacturing process: quality grading, jewelry crafting, and final assembly into finished pieces.
Types of Pearls We Farm in Phuket
Our farm cultivates four distinct cultured pearl types, each with its own oyster, timeline, and signature look.
- Mook Sapam Pearl (Mabe): Cultivated from the Pteria Penquin oyster over 10 to 12 months. Andaman Sea variants produce unique bluish or golden tones with a rainbow shimmer.
- Akoya Pearl: A small, perfectly round pearl (2 to 9 mm) from the Pinctada Fucada oyster. Cultured for around 12 months after a precise nucleus implantation.
- South Sea Pearl: Large round pearls (11 mm and up) in white, gold, and black tones. Grafted at age 2, with another two years to develop, making this the highest-priced cultured variety.
- Rather Round Pearl (R.R.P.): Our own patented invention, combining South Sea and Mabe characteristics into a distinctive golden-rainbow pearl. Research began in 1998, with the first successful pearl in 2002.

Sustainable Oyster Pearl Farming Practices in Thailand
Sustainable oyster pearl farming practices in Thailand depend on one simple fact: pearls cannot be raised in polluted water. Clean, healthy waters are the foundation of the business, which is why sustainability has been built into how our farm operates.
Recognized Sustainability Credentials
- Outstanding National Farmer Award (2009): Brackish Water Aquaculture category
- Green Industry certification (2016): Following the Thai Ministry of Industry’s sustainability framework
- ISO 9001:2015 certified: Quality management standard
- Thailand Trust Mark (2015): Awarded by the Department of International Promotion
- Geographical Indication (GI): The first and only pearl company in Thailand with full-cycle GI certification
Care for Oysters and the Marine Environment
Sustainable practice runs through each step of the cycle: healthy breeder oysters are set aside rather than harvested, every implanted oyster is monitored for 30 days of recovery, shells are cleaned regularly during culturing, and only mature pearls are harvested so the rest can continue to thrive on the raft systems.

Thailand’s Pearl Farming Heritage
Our family began farming in Sapam Bay in 1967, and the first pearls were sold commercially from this farm in 1976. By 1990, the third generation had developed pearl cultivation into a complete factory-and-farm operation. The AMORN brand was established in 2011, and our pieces have since featured at international beauty pageants including Miss World Singapore, Miss Thailand World, Miss Myanmar World, and Miss World Australia.
