Otto Jakob is a contemporary jewellery designer working with precious materials, enamel and gemstones.  Born in 1951 in Germany; Otto's fascination in jewellery began early when, at seventeen he began a self taught study in the art of goldsmithing with pieces created by the Etruscans, Celts and Greeks.  Through research, experimentation and looking at techniques used in Roman, Medieval and Renaissance jewels he seeked to recreate these design periods in a contemporary manner.   His work is widely sought after and represented in many private collections in Germany, Europe and the USA where he has been compared to his Parisian contemporary JAR.  Otto Jakob believes his jewels should be either worn or displayed as works of art in their own right.
