The rock crystal used to make this brooch is colourless. However, the resin that holds together the singular gemstone pieces is coloured with different pigments, and so the brooch shimmers in a gradient from turquoise to raspberry.

This is a purple amethyst brooch. The gemstone pieces are assembled in a rectangular shape held together by pigmented resin, that partially amplifies the colour of the amethyst while preserving the translucency.

This agate brooch is in variations of blue. Resin and gemstone are kept in the same colour. Only opacity variations give a clue as to which is the agathe and which is the resin.

Here is a rhodonite brooch in light to very dark raspberry tones. The gemstones are fixed by a pigmented resin. Around a rectangular central plate smaller elements are assembled like a brick wall.

This is a group of four brooches or wearable sculptures. The rock crystal itself is colourless and translucent. It is the pigmented resin that adds the colour. The pigments create gradients from light yellow to orange tones and intense red. The gemstones are assembled in geometric forms.
