12x Medium African Tumble Stone - Bloodstone - Sephtonite

No. Natural inclusions, small surface pits, variations in polish and slightly irregular shapes are normal with tumble stones. These characteristics should not automatically be treated as faults unless a piece is clearly broken or badly damaged.

Keep each variety in a clearly labelled compartment rather than combining similar colours in one bowl. This is particularly useful for jaspers, agates and tiger’s eye varieties, which can look surprisingly alike to someone new to crystals.

Potentially. Gemstones vary considerably in hardness and toughness, so repeated rubbing or knocking can leave softer stones scratched or chipped. Divided trays or separate containers are preferable for longer-term storage and busy self-select displays.

A soft cloth is the simplest option when the exact mineral or treatment is uncertain. Many coloured gemstones tolerate mild soapy water, but steam, ultrasonic cleaners, chemicals and high heat are not suitable for every stone, so one cleaning method should not be recommended across the entire range.

Not necessarily. Clear labelling with the gemstone name is a good starting point, while staff can gradually learn the traditional associations customers commonly ask about. If discussing crystal properties, present them as traditional or spiritual beliefs rather than proven health benefits.
