Freshwater Pearl Jewellery: Why Every Piece Is Unique

Freshwater pearls can differ in shape, colour, lustre and surface. Those details give pearl jewellery its character, but they do not tell you everything about a pearl’s origin. When choosing a piece, read its material description alongside the photographs.

Natural and cultured pearls: what is the difference?

A natural pearl forms without human intervention. Cultured pearls develop with human involvement in the growing process. Both can form in freshwater environments, so “freshwater” does not mean “natural”. Freshwater cultured pearls are a widely used category in jewellery.

An irregular shape is not proof that a pearl is natural rather than cultured. For a particular necklace, bracelet or pair of earrings, use the product’s verified material details rather than its name or appearance to establish what it contains.

Mother-of-pearl and pearls: what is the difference?

Mother-of-pearl, also called nacre, is the lustrous inner layer of certain mollusc shells. The Western Australian Museum’s explanation of mother-of-pearl describes its layered structure and reflected light. A pearl is a separate formation within a mollusc; natural and cultured pearls differ in how that formation begins, as explained in GIA’s pearl overview.

The terms do not name the same form. For example, Dalia Mini Pearl Huggies Earrings list five small mother-of-pearl accents on each hoop. The Lulwa Pearl Shell Necklace, pictured in the styling section below, lists one white baroque pearl beside separate shell and sun charms. Use the individual product’s material description; a name or photograph alone does not establish freshwater or saltwater origin, or natural versus cultured classification.

What to look for in a pearl

Shape may be round, oval, drop-like or irregular. Colour, surface and lustre also affect its appearance. Lustre describes the quality of reflected light: brighter, sharper reflections create a different effect from a softer glow.

Compare close photographs and any measurements listed for the specific piece. Do not assume two pearls will match exactly, or that every visible surface mark is a defect. If a detail matters to your choice, ask about the specific piece before ordering.

Styling pearl jewellery

Start with one pearl-accented piece as your focal point, then add another detail only if it helps the combination feel balanced. The Lulwa Pearl Shell Necklace pairs a ribbed shell with an irregular white baroque pearl and an eight-point sun; the Margo Pearl Necklace has gold-tone and silver-tone options with a curved row of white oval accents. For an earring-led look, the Marley Pearl Crystal Earrings pair clear round tops with white oval drops, leaving room for a simpler necklace.

Caring for pearls

Wipe pearls gently with a soft, clean cloth after wear. Keep perfume, hairspray and harsh cleaning products away from them. Store pearl jewellery separately from hard or rough pieces to reduce scratching, and avoid hot, dry storage conditions.

Never use an ultrasonic or steam cleaner on pearls. If a strung piece has been cleaned, let its string dry fully before wearing it again. All Reef & Rose pieces are designed to be waterproof and tarnish free with PVD plating, including silver-tone styles. Follow the Materials & Care guide for gentle maintenance of the complete piece.

PVD refers to the metal finish; pearls still need gentle surface care. For guidance on rinsing and drying the complete piece after ocean or pool exposure, read our after-ocean jewellery care guide.

Explore necklaces, earrings and bracelets, then check each product’s materials, any listed measurements and care instructions.
