What to expect

The original listing cautions that minor natural flaking can occur. Some options display weight ranges with different punctuation; use the listed numeric range rather than assuming a fixed size.

The photographs show representative natural material; colour, crystal habit, markings and shape vary from stone to stone.

Care and dispatch

Handle gently and avoid harsh cleaners, impacts and prolonged strong sunlight. Fragile mineral surfaces may chip or abrade. Carefully packed and dispatched from the UK.
