Two 19th century Micro Mosaic forget me not flower trinket boxes

After a long time I show my new acquisitions again, 2 micro mosaic forget-me-not trinket boxes. The two boxes are the same size but have a different color background. One rose and the other white.
It is very interesting that you can see the age of the boxes very well on photo number 3 and 4. Because with micro mosaic, the older the pieces are, the finer the tesserae (or pieces of (cut) glass). The last photo is of all my boxes together. Including one can be worn as a medallion. This one is also a bit smaller than the other oldest boxes (middle photo number 2).
