Helvetia 18K Gold Tahitian Semi-round 9-11 mm

Our stunning black pearls are ethically sourced in the crystal clear waters of Polynesia. Treasured for their rich, peacock-like colours and natural shapes, our Tahitian pearls are ecologically farmed and of AAA quality. Oceano provides a certificate of authenticity with each pearl.

Pearls are the only gemstones whose shape, lustre, and colour cannot be modified. They are a direct creation of the ocean, making each pearl one-of-a-kind.

Each of our high quality Tahitian pearls is an investment in one of the ocean’s most unique natural treasures. Their natural colours vary from green to grey to aubergine, with no two pearls the same.

Baroque pearls: prized for their organic silhouettes, baroque pearls are Intentionally imperfect. Their irregular shapes are just as nature intended.

Sourcing
Farming pearls is the most ecological way to find pearls without depleting the environment. Pearl oysters need crystal clear water in order to thrive, as they act as natural filters for the ocean and cannot survive in polluted areas. We carefully choose eco-friendly, certified Fair Trade Origin farms whose practices respect the environment and the ocean.
It takes from 3-10 years for Tahitian pearls to mature and be harvested. Once the Tahitian pearl has grown to 7mm, pearl farmers can respectfully remove it without damaging the oyster. The oyster will only produce 1 or 2 more pearls in its lifetime.

Our Fine Collection is made from 18K solid gold, responsibly sourced from the UK’s leading jewellery district. We collaborate with ethically-conscious suppliers who provide fully traceable recycled gold, certified by the Responsible Jewellery Council. This recycled gold offers the same premium quality as non-recycled gold, but with a reduced environmental footprint. By choosing 18K solid gold, you're investing in a lasting heirloom.
