Gemstones are uniquely precious crystals prized for their appearance. Though they grow organically, they form habits based upon their molecular composition and environment. They also occasionally fracture and break when put under immediate or long term stresses. The city fabric is analogous to this condition - particularly that of Philadelphia. The city is based upon a regular, rigid grid, and condemned to its habit. In certain areas this crystalline structure inevitably fractures as it meets natural boundaries or connecting synthetic boundaries. These moments of fracture, whether along striations or in complete fragmentation are areas of opportunity in an urban setting.
