They are designed to be used as pendulums, not simply displayed as crystal ornaments. The rounded gemstone can swing freely from the chain, although customers may prefer pointed pendulums if they like a clearly defined tip.

There is no mechanical calibration or technical set-up required. Within traditional dowsing practice, users often establish their own movements for responses such as “yes” and “no”, so a short explanation at the point of sale can be helpful for first-time buyers.

For routine care, use a soft, lint-free cloth and avoid abrasive cleaners. Because different gemstones have different tolerances, it is safer not to recommend steam, ultrasonic cleaning or strong chemicals as a universal cleaning method for the whole range.

Individual hooks, jewellery-style display cards or divided trays work better than piling several pendulums together. For stored stock, keeping each chain separated or laid flat will save staff time and reduce unnecessary pulling on the fittings.

They are designed as pendulums rather than jewellery. The chain is approximately 170 mm long and intended for holding during pendulum work, so retailers should avoid presenting them as necklaces unless a particular item is specifically sold for that purpose.
