Fossas was commissioned to do a ring commemorating the 25th anniversary of marriage, by the wife of a well known architect. Aware of his successful career and refined taste, the client and Fossas decided to present a series of drawings for him to choose and this way integrate him to the process. 

The design was made of two 18 karat yellow gold bands, joined together by twenty five 18 karat white gold bars—representing both people united during twenty five years.
