Italian ~ Mosaic, Micro-Mosaic & Pietra Dura Jewels Of The Past

As an update to this post – I stand corrected. I read on an antique jewellery blog, that the term for this example would be simply mosaic. I described it as micro, because it has tiny bits of glass arranged in a mosaic. The term micro mosaic actually refers to mosaics so fine, they look like a painting. The finer micro-mosaics were usually set in gold. Another term in the same genre, is pietra dura. It is the Italian term for the use of (gem)stones in a mosaic, as opposed to glass.
