18ct White Gold Paua Pearl Diamond Olivia Plus Necklace
18ct White Gold Paua Pearl Diamond Olivia Plus Necklace
A 18ct white gold pāua pearl necklace featuring a rare Arapawa blue pearl grown on Arapaoa Island in New Zealand's Marlborough Sounds. The Diamond Olivia Plus design references the elegance, while allowing the natural iridescence of one of the world's most uncommon pearls to take centre stage.
Each pāua pearl is grown over eight years in our land-based tanks, fed by pristine ocean water surrounding the island. Over time, layers of nacre form depth, lustre, and the distinctive blues, greens, and subtle rainbow overtones unique to pāua pearl jewellery. No two pearls are ever the same, and these pearls cannot be cultivated anywhere else in the world.
The refined 18ct white gold with diamonds setting is intentionally understated, designed to highlight the pearl's natural beauty without distraction. This necklace reflects a considered approach to pearl jewellery, one that values patience, precision, and longevity.
As New Zealand's only land-based pāua pearl farm, we grow our pearls using ethical, zero-waste practices that support marine conservation. Baby pāua are returned to the wild, and every pearl is cultivated without impacting ocean ecosystems. Each necklace is finished with care and comes with a certificate of authenticity detailing your pearl.

Pearl Grades Explained
Pāua pearls are graded on lustre, surface, and colour saturation. No two pearls are identical, grade reflects character, not worth.
A Grade
Exceptional lustre with a mirror-like surface and very few imperfections. Deep, even colour saturation throughout. Our finest.
B1 Grade
Very good to excellent lustre with minor surface imperfections. Strong colour saturation, a beautiful everyday pearl.
B2 Grade
Very good lustre with moderate surface markings, which may include conchiolin lines, the natural growth rings visible on pāua and abalone shell. Colour can be multicoloured and vivid.
C1 Grade
Our most popular grade. Good lustre with more visible surface character and rich colour. Loved for its warmth and individuality.
C2 Grade
Fair lustre with heavier surface markings, including conchiolin deposits. Each pearl is distinctly its own.
C3 Grade
Our most characterful grade. Lustre is soft and surface markings are pronounced, you can often feel the texture by touch. Deep, complex colour.
A Note on Colour
Blue Pearls
The rarest and most valuable. Prized for their deep, oceanic hue.
Orient Pearls
Carry two or more colour overtones, shifting in the light.
Regular Pearls
Show one or two colours, classic and consistent.
Nacre Pearls
Thicker pearls used in rings and bracelets.
Conchiolin Lines
The natural boundary between two layers of nacre, visible as dark markings on the pearl's surface. A sign of the pearl's growth, not a flaw.
Wearability: Gems and mineral hardness, their resistance to scratching and abrasions is measured on the Moh's scale from 1 to 10. Like other pearls, Abalone Paua Mabe pearls require care because they can be scratched or abraded, as they have a hardness of 2.5 - 3 on the Moh's scale. Therefore, it is crucial to know that popular gemstones with higher hardness like diamonds, sapphires or emeralds can be susceptible to fractures and damage if worn without consideration. However, some people may be surprised to discover that a high hardness on the Moh's scale does not mean that these gemstones are indestructible. Therefore, we always recommend taking care of precious pieces of jewellery.
Pearl stability: Industry experts have estimated that a range between 85 to 95% of the global pearl production may be subject to a specific type of treatment, so it is better to stay away from dyed, impregnated, or coated pearls, as these treatments might alter their appearance or stability over time.
No treatments: Arapawa Blue Pearls are proud to disclose we do not treat our cultured Abalone blister pearls. So, you can enjoy the stability of your Paua pearl engagement ring. We would love to hear about your ideal proposal and dream engagement ring design. If you would like a cultured mabe pearl with no treatments, a certified and sustainable New Zealand origin, and set in a piece of jewellery made locally, we are ready for you! Learn more
