Gold plated ring with nautilus. Hypoallergenic. 
The natural shell Nautilus is very popular for its spiral geometric shape, being the subject of mathematical studies of the famous formula "Golden Ratio", the Fibonacci sequence. The shell has a shiny pearly layer, very similar to mother of pearl.
Its symbolism is related to spiritual evolution, the complexity and breadth of the mind and the development of thoughts. It also represents beauty and perfection. In addition, the energy of the ocean is present in its composition, so its energy is linked to purity and flexibility.
