Materials & care
Worth keeping, easy to keep.
Heirlooms earn their name by outlasting trends. Here is what we make from, and how to look after it.
Our materials
18k Recycled Gold
Our signature metal — recycled, warm in tone, and heavy enough to feel permanent. Never plated.
14k Recycled Gold
A lighter, every-day weight with the same sea-worn warmth — for pieces meant to never come off.
Sterling Silver
Recycled and matte-finished for a cool, driftwood tone that pairs with our gray-green stones.
Sea Glass
Foggy blue, gray-green and milky white — found on the shore, hand-polished and set in protective bezels.
Care guide
- 01Remove jewelry before swimming, cleaning or applying lotion and perfume.
- 02Store pieces separately in a soft pouch or the Tidal Relics box to avoid scratches.
- 03Clean gold and silver with warm water, mild soap and a soft cloth.
- 04Sea glass is tough but not invincible — keep it away from hard knocks and ultrasonic cleaners.
- 05For a full refresh, book a complimentary in-house sea-worn re-finish at any appointment.
Every Tidal Relics piece carries a limited lifetime warranty against manufacturing defects, and is re-polished free for the first two years. .
