Black Tourmaline Crystal Bracelet – Grounding Stone (8mm)

An everyday stretch bracelet of 8 mm faceted black tourmaline beads with a silver-tone charm.

Why this stone wears well

At Mohs 7–7.5, black tourmaline is one of the hardest stones we sell, which matters more for a bracelet than for anything else we make: beads knock against desks, keyboards and door handles all day. Faceted beads catch light along their edges, and because the stone takes a high polish without being brittle, those edges stay crisp rather than scuffing to a matt grey.

A practical authenticity check: schorl grows in three-sided prisms with fine lines running lengthwise down the crystal. On a polished bead you can often still see those parallel striations. Dyed black glass and dyed howlite show none.

Wearing and care

• Roll it on and off rather than stretching it wide — the elastic is the part that eventually fails on any stretch bracelet, not the stone.
• The stone shrugs off daily wear; the silver-tone charm is what will tarnish and wear. Keep perfume, sanitiser and hairspray off it, and take it off before showering.
• Wipe with a soft dry cloth. No jewellery dips or ultrasonic cleaners — those attack the charm's plating.
• Cleanse dry if that is part of your practice: sage smoke, sound, or a selenite plate.

Which hand

Convention puts receiving stones on the left and expressive ones on the right. There is no mechanism behind it — wear it on whichever wrist is comfortable.

Natural variation

Texture, finish and bead pattern differ piece to piece — characteristics of natural schorl, not defects.

What this is, and what it isn't

The mineral. Black Tourmaline's proper name is schorl, an iron-rich boron silicate. At Mohs 7–7.5 it is one of the hardest stones we sell and stands up well to daily wear. It grows in long three-sided prisms with lengthwise striations — you can often see fine parallel lines on a polished bead, which is a good authenticity check.

One real physical property, stated precisely. Schorl is genuinely piezoelectric and pyroelectric: squeeze it or warm it and opposite ends of the crystal develop opposite electrical charges. This is measurable and has been known for centuries — it is why heated tourmaline attracts ash, and Dutch traders once called it the "ash-puller". It is also the origin of most modern claims that tourmaline emits energy or blocks radiation. It does not. The charge appears only during a change in pressure or temperature, is vanishingly small, cannot be felt, and does nothing to electromagnetic fields, Wi-Fi or phone signals. We mention it because it is interesting and true, not as evidence for anything more.

The tradition. In crystal practice Black Tourmaline is the protection and grounding stone, linked to the Root chakra. That association comes from tradition and spiritual practice, not from the piezoelectric effect above or any other measured property, and the chakra system is a spiritual framework rather than a scientific one.

The evidence. There is no peer-reviewed scientific evidence that crystals absorb negative energy, shield against radiation, or produce physical or psychological effects. Where people find value it comes from the practice — the intention set, and the reminder worn.

Please note. Nothing on this page is medical or psychological advice, and this bracelet is not a treatment for any condition and offers no protection from electromagnetic radiation or any physical hazard.
