Long before jewellers discovered gold or learned to facet gemstones, the ocean had already been creating its own jewels. Aragonite — the mineral that forms both pearls and mother-of-pearl — is one of nature's most patient achievements: a crystalline calcium carbonate built layer by microscopic layer inside the shell of a living creature.

What Aragonite Actually Is

Aragonite is a polymorph of calcium carbonate, chemically identical to calcite but with a different crystal structure that makes it slightly denser and distinctly more lustrous. It forms under cool, high-pressure conditions — exactly the conditions found in the ocean depths where molluscs live.

When a mollusc coats an irritant with thousands of concentric aragonite layers, each only a few hundred nanometres thick, the result is nacre — the material we call mother-of-pearl. The iridescence that makes pearl so captivating is not a pigment or dye; it is an optical phenomenon caused by light diffracting between those ultra-thin layers, each wavelength bending at a slightly different angle.

No two pearls are alike. Their colour, shape, and lustre depend on the species of mollusc, the water temperature, the mineral composition of that specific bay, and the length of time the creature was left to work undisturbed. A single pearl of exceptional quality may represent five or more years of growth.

The Pearl's Journey into Alex Yuvero

In the Alex Yuvero collection, pearl appears not as a traditional bridal stone but as something stranger and more contemporary. The pieces pair freshwater and baroque pearls — with their organic, irregular forms — against oxidised sterling silver and 18-carat gold, creating a deliberate tension between the raw and the refined.

Baroque pearls are the ones the industry historically rejected: off-round, asymmetric, bulging in unexpected directions. We chose them precisely because that imperfection is where character lives. Each baroque pearl is a record of its own growth history, a shape that no factory could reproduce.

Why Pearl Endures

Pearl is among the oldest known jewellery materials. Archaeologists have found pearl ornaments in ancient Persian royal tombs, in Aztec burial sites, and in the treasuries of every major civilisation that had access to the sea. Roman women wore pearls to signal wealth and status; Renaissance portraits show them as symbols of purity and feminine power; in Japan, the cultured pearl industry transformed an entire coastal economy.

That longevity is not accidental. Pearl has a warmth that mineral gemstones lack — it was alive, and that aliveness is visible in its surface. It absorbs body heat. It responds to the oils in your skin. Worn regularly, a pearl's lustre can actually improve over years of contact.

How to Care for Pearl Jewellery

Because pearl is organic rather than mineral, it requires slightly different care than metal or stone jewellery:

• Put your pearl jewellery on last, after applying perfume, hairspray, or cosmetics — chemicals degrade nacre over time.
• Wipe with a soft, dry cloth after wearing to remove skin oils and sweat.
• Store separately, wrapped in soft cloth or a dedicated pouch; pearls scratch easily and should not touch metal or harder gemstones.
• Keep away from ultrasonic cleaners, which vibrate the nacre layers apart.
• Occasionally wipe gently with a slightly damp cloth — pearls benefit from a small amount of moisture and should not dry out completely.

Treated with care, a piece of pearl jewellery can outlast every synthetic material on the market and become exactly what we design it to be: something that passes from one person to the next carrying the weight of time.
