Are the tourmalines natural and uncut?

Yes. Each is set in the shape it grew in, not cut to a standard.

The colourless variety of tourmaline. The name comes from the Greek for without colour. One of the twenty-one pieces here carries it.

Will my piece match the photograph?

The silver will. The stone will not - each is photographed individually because each is different. What you see in the listing is the stone you receive.

Cloth or silver cleaner on the metal, no ultrasonic cleaning. Raw crystals keep internal flaws that cutting would have removed.

Q: Why do the colours differ so much?

Tourmaline takes its colour from trace elements caught during growth - iron, manganese, lithium, chromium. A single crystal can even shift hue along its length.

Q: How heavy are they?

Between 2.5 and 5.9 grams. The stone decides the final mass, so two pieces of the same model can differ.

Twenty-one earrings built around uncut tourmaline in 925 silver: seven green, seven pink, three grey, one purple, one transparent, one achroite. From Rp 2,850,000.

Tourmaline is a boron silicate that grows in long prismatic crystals with a striated surface — and it comes in more colours than any other gem mineral. Green, pink, grey, purple, transparent, and achroite: the colourless variety, named from the Greek for "without colour".

What tourmaline is

Every piece on this page is built around a tourmaline that was never cut. The crystal is set in the shape it grew in, so the silver has to be made for that stone and no other.

Why the colour varies so much

Tourmaline's colour comes from trace elements caught during growth — iron, manganese, lithium, chromium. Change the trace, change the colour. A single crystal can shift hue along its length, which is why two stones from the same pocket read differently on the ear.

Twenty-one pieces here, and no two stones repeat: seven green, seven pink, three grey, one pink-grey, one purple, one transparent, one achroite.

What is in this collection

All twenty-one are earrings, in two forms. Prices run from Rp 2,850,000 to Rp 3,920,000.

Classic Amulet — the stone held open, silver reduced to what the crystal needs to stay put. Eight of the twenty-one.

Thorn Amulet — the THORN form carried into volume. THORN is the third form of the brand: a thorn with sharp angles, bringing together CNC and 3D-modelling. Thirteen of the twenty-one.

Weights run from 2.5 to 5.9 grams. The stone decides the final mass, so two pieces of the same model can differ.

Every piece is numbered

Classic Amulet Earring #28, Thorn Amulet Earring #23. The number is the running count of that model — the twenty-eighth made, not the twenty-eighth copy. When a number sells, the stone in it does not exist twice.

What we do not claim

We do not sell protection, energy or healing. What people believed about tourmaline is cultural history; we sell the object. Meaning is something you bring.

Care

No ultrasonic cleaning — raw crystals keep the internal fractures that cutting would have removed, and ultrasound finds them. Cloth or silver cleaner on the metal, keeping liquid off the stone. Take the piece off before the pool.
