Vintage silver Modernist Brutalist pendant & 24" chain necklace. 60s/70s retro jewellery hallmarked. Mid century MCM, stamped EH. Sterling

A beautiful retro Scandinavian Brutalist style silver pendant on a 24" silver necklace. The pendant is hallmarked 'silver' and I would assume it's Sterling 925 grade and by a British artist (it's stamped EH). Circa 1960s or 1970s.
The 2mm wide chain is stamped 'sterling' on the opener (really hard to see). All silver - weighs 15g total.

It's Modernist, Minimalist and Brutalist in style - a series of random raised 3D lines/shapes in a cluster (like standing stones, bricks or wedges) forming a rough oval shape. Mounted on a lightly curved oval shape pendant. Please study photos, it's hard to explain!

A petite but statement piece, quite possibly unique. Handmade. Stamped to the back with the maker's mark 'EH' within a shield shape logo.
Perfect gift idea.

Pendant is 27x12mm.

Price includes P&P to the UK.
(I'm unsure of the technical terminology for the chain type and the clasp, so please see pics).
