Spiny substance is a handcrafted ring in 925 silver. At the heart of an ecosystem where the boundary between mineral and living seems blurred, singular biodiversity has developed. New forms resembling a new variety of thorns have acclimatized. These new species evolve in a strange environment saturated with precious minerals. Nicknamed "Spiny Substance", these creatures represent an exceptional fusion of nature and metal, where silver spines are much more than mere weapons. Impregnated with a toxic venom based on 925 silver, they use these spines to protect their masters and inject a poison that first creates a tingling sensation, then numbness. This non-lethal but highly effective venom protects them and their wearer. The Spiny Substances, guardians of this mineral kingdom, play a crucial role in maintaining a subtle balance between defense and harmony. In this glittering landscape, these creatures draw their energy from the surrounding minerals, absorbing subtle energies to sustain their growth and produce their venom.
