Each element of the Fibonacci collection consists of rings that grow in height according to the model of evolution of the sequence, in which the next number is the sum of the two previous numbers.
The relationship between a number and its predecessor is also equal to the sezione aurea, which was used to sizing the collection.
The Fibonacci sequence and sezione aurea are often to be found in nature; flowers have a quantity of petals matching the numbers of the sequence: lilies have three petals, buttercups have five, daisies have thirty-four, fifty-five or eighty-nine.
The container (the vase) and its content (the flowers) are then generated by following the same principle:
design strives to achieve the same harmonic dimension of nature, which in the Fibonacci vases materialized in an absolute essentiality. The rings generated by the sequence constitute the evidence of the production process: the horizontal lines to separate the rings are in fact the result of a process of hand-throwing.
