Vintage 60's Brutalist Jack Boyd Era Copper with Fossil Spores Petrified Wood

Found at an estate sale of a professor who lived at Habitat 67, the modernist cube dwellings in Montreal. His unit was packed with books, geological specimens, plants, and art. This amazing pendant was part of the treasures I found there! It is a statement pendant in the style of Pal Kepenyes Jack Boyd Anne Dick David Yurman Putnam, unsigned. Measures approximately 3 inches long by 1 1/2 inches wide. The base metal is copper, and has petrified, fossil wood with small plant or flower fossil spores throughout. Whoever the artist was, was very clever, and placed small copper dots in the spores that were empty. It truly is one of a kind, and is sturdy and in great shape. I wish I knew who the jeweler was, but this does date to the 1960's, when the brutalist movement was in full swing. In overall very good vintage condition with wear consistent to age and material, please inspect the numerous photos for complete condition details. I welcome any questions you might have, and I gladly offer combined shipping. The auction photos provide the truest description of condition so make sure to inspect them closely as I do not accept returns. I package and ship the same day payment is made. This will be sent insured.
