Eyris Pearls, it’s a story of the vision of New Zealander Roger Beattie, who in 1989, established the first ocean based blue pearl farm at Whangamoe Inlet on New Zealand’s Chatham Islands. His understanding of the pearl fishery and his empathy, not only for the environment, but also the very rhythms of nature’s life cycles, led Roger and his team to embark on a project which would see the creation of a new gem, unparalleled in its beauty and colour.

Eyris Pearls

These unique pearls are fished for in a sustainable way with a pure understanding and empathy, not only for the environment but also the very rhythms of nature's life cycles. To achieve this sustainability, the pearls are individually dived for and collected by hand. A certificate detailing the divers' name and a thorough description of the pearl, including; size, colour, and quality, accompany every pearl harvested so you can remain certain of their authenticity.

You can keep it simple with a single stone or adorn it with an array of gemstones to add pops of colour and sparkle. Think of the Bubbles pendant as the starting point for you to layer upon in your own unique way.
