In ‘Jewellery from the Orient. Treasures from the Bir collection’ by Wolf-Dieter Seiwert, 2009 Arnoldsche Art publishers, Stuttgart. ISBN 978-3-89790-319-7,
there is a small chapter ‘From the Mediterranean to the Atlantic’ with some nice examples of Grande Kabylle jewels, amongst which 2 fibulae.

The only book I have so far seen completely dedicated to Algerian jewels is a catalogue to an exhibition ‘Bijoux & parures d’Algérie. Histoire, techniques, symboles’, 2003, Somogy éditions d’art, Paris. ISBN 2-85056-642-X

There is also a book by Henriette Camps-Fabrer ‘Bijoux berbères d’Algérie. Grande Kabylie, Aurès', from 1990, which I have not seen and is hard to find.

If you google images ‘fibules Grande Kabylie Algérie’ then you will find some examples similar to yours.

Hope these little bits are helpful.

And last 'pour le plaisir des yeux' as they like to say in Morocco:
Enclosed a picture of a head ornament made NOT by an Algerian, but by a Moroccan silversmith from Tiznit. He died quite some years ago but was well-known - still is amongst older jewellers in Marrakech- for wanting to improve and refine the Algerian style of Grande Kabylie. He was passionate about it. If you compare it with the Kabyllie pieces, it is indeed a more subdued style. Still, one wonders when the day comes no one will remember this, will it be classified as Algerian?
