Every Castello piece begins with a natural stone. Because each gemstone forms over thousands of years deep in the earth, no two are ever identical — the small variations in colour and pattern are what make a handmade bracelet truly one of a kind. For centuries people have also given these stones meaning, wearing them not only for their beauty but for the qualities they are said to carry.
Here is a short guide to some of the most-loved gemstones in our handmade bracelets, necklaces and rings.
Lapis Lazuli — wisdom & truth
The deep celestial blue of lapis lazuli has been prized since antiquity, from the jewellery of the pharaohs to the robes of Renaissance painters. It is traditionally associated with wisdom, honesty and inner clarity, making it a favourite for those who value calm, considered thinking.
Onyx — strength & protection
Sleek and black, onyx is the grounding stone. It is long linked with strength, focus and protection from negativity — which is why it pairs so naturally with our more masculine, minimal designs.
Tiger’s Eye — courage & confidence
With its warm golden bands that shift in the light, tiger’s eye is the stone of confidence and courage. It is said to help you stay balanced and grounded while pursuing what you want — a quietly powerful everyday companion.
Howlite & Moonstone — calm & balance
Soft white howlite and luminous moonstone are the gentle stones of the collection. Both are associated with calm, patience and emotional balance, and their pale tones make them endlessly easy to wear with anything.
Amethyst — clarity & serenity
The violet glow of amethyst has always been tied to serenity and clarity of mind. It is a stone of quiet luxury — understated, elegant and timeless.
How we set them
At Castello, every stone is hand-set in 925 sterling silver in our workshop in the Medieval Old Town of Rhodes. Because the stones are natural, we choose and string each one by hand, so the piece you receive is genuinely unique. You can even choose your own wrist measurement so it fits perfectly — see our bracelet size guide.
