It is assumed that nicolo can be identified with the antique stone that Pliny the Elder called aegyptilla. It is onyx, of specific bluish white upper layer and very dark brown or black lower layer. Furthermore, we show how the imitations of gems are created with the use of natural or artificial materials. Also, we describe gems with some of their original characteristics modified in certain treatments, most frequently the change of natural gem colour. From the gemmological aspect, a gem is natural if all of its natural features are preserved. This paper highlights the importance of gems, especially in the Ancient World. ДЄn interdisciplinary approach to the research of gemmology and archaeology has discovered a variety of information which simultaneously enrich the achievements of both disciplines.
