French designer Matali Crasset has created a range of rings with talon-like silver settings to add to her collection for Parisian jewellers Le Buisson.
The rings feature single globe-shaped pieces of red agate, turquoise, yellow jasper or lemon quartz, held in a setting made of seven spurs, which taper into rounded ends.
The sections of the setting extend around and above the semi-precious stones, which are held on a silver band.
The rings add to a previous collection Crasset designed in collaboration with the Centre Pompidou arts centre for French jewellery brand Le Buisson, which featured pendants with the same multi-fingered settings.
The jewellery line was an extension of an installation Crasset created for the Centre Pompidou in Paris, which saw her transform a children's gallery into a playground of artificial "neo-vegetation" – as the designer termed it.
"This is a world closely linked to jewellery's natural passion for plants and flowers," said Crasset. "The idea to design a piece of jewellery came naturally from these common links."
An earlier partnership with Le Buisson marked the designer's first venture into the world of jewellery, with a series of pieces that featured tiny figures scuba diving, flying off with a jewel, and perched on a unicycle.
Crasset has also designed sofas made from a system of interchangeable modules, a series of wicker pieces made to promote traditional Zimbabwean weaving techniques, and multi-faced concrete presentation pieces.
Earlier this year, Klemens Schillinger transformed the ring into a jewellery-style infographic, creating a series of pieces that were sized to reflect the fluctuating price of gold over the past five decades.
Other unusual jewellery designs include Ashley Heather's collection made using silver salvaged from discarded electronic products, and a range of rings made of small but fully functional architects' implements.
