These are tests for a novel type of living jewellery that is made from pigmented bacteria, and a specially formulated transparent growth medium.  The bacteria in these liquid crystal gemstones uniquely respond to their wearers and in doing so the jewellery records its wearer’s history and that of their external environment.  Each BioGem is consequently unique, it’s internal patterns, being an intimate 3-Dimensional recording of its wearer’s own unique  past.
