Dynamic Geometry is the necklace that gives the name of my latest contemporary jewellry collection, inspired by the Dacian Treasure, a collection of ornaments consisting of many regionally distinct styles realized by the ancient people living on the current territory of Romania more than 1000 years ago. The necklace takes the structure of the Sanctuary, made of three concentric circles. In order to realize it, I used 10 hemispheres made of silver and brass. There were 5 silver and 5 bronze hemispheres symbolizing the 5 male and 5 female days in the Dacian calendar. According to historical documents, the Dacians divided the year into 360 days, 36 weeks, each week having 10 days. The 10 days were subordinated to planets, each week having five masculine and 5 feminine days.
