Vintage Artisan Quartz Sliced Stone & Beads Brooch-Boutique

I don’t remember this designer’s name or studio but we carried and sold a lot of her pieces in the 1980s -90s. Her unique designs always consisted of an agate slice in its natural state and her embellishment of glass & clay beads and pearls. In this Brooch design it sits horizontally but we can alter if you prefer it vertically. I cannot remember the designers. Same but her pieces were often featured in top fashion magazines. Definitely statement pieces. 7” wide
