Circa mid-century, this modernist Mexican bib necklace is the work of "MGI". It's an Antonio Pineda design, and this piece matches the quality and construction perfectly.
This necklace has seventeen polished onyx crescents, and it certainly makes a statement.
A very substantial piece, weighing 131.3 grams.
Very difficult to accurately measure the closed, wearable length, but I would say about 15". The drop in front is 3".
Signed and hallmarked "MGI Taxco Mexico 970", and a bottle shape with MGI inside, along with the eagle assay 3.
In excellent vintage condition. Stones are perfect. Clasp closes with a tight and secure tongue in groove.
