This stunning Line Vautrin geometric Talosel brooch pin features an encrusted rectangular shape with pink-colored mirrored glass in a checkerboard pattern. The glass associated with Talosel is a unique technique created by Line Vautrin, in which she used cellulose acetate that was fractured into tiny splinters and worked with heat. The creation process of the Talosel jewelry had many stages, including making the mirrors, tinting them, molding the Talosel, and embedding smaller mirror fragments into it. A security closing clasp is present at the back.
