The strong colours are deliberately added. The Moroccan calcite geodes are painted, including the crystals inside, while the quartz clusters have enhanced finishes. It is best to make this clear to customers rather than presenting them as naturally coloured specimens.

No. The underlying stone and crystal formations naturally vary in shape, size and structure, so each piece will have its own character. Online retailers should treat product photographs as representative rather than exact.

Give each piece enough room so crystal points are not constantly knocking against neighbouring products. Small stands, risers and lined shelves work well, particularly for creating different heights within a crystal display.

For normal shop dust, use a soft brush or dry cloth and handle the coloured surfaces gently. Avoid soaking the pieces or using household cleaning products, as painted and enhanced finishes may react differently to moisture or chemicals.
