Vintage unsigned baroque style, ornate ruby red and clear rhinestone necklace, fabulous quality

Wonderful vintage necklace consisting of rhinestone embellished silver tone ornate panels in an elaborate baroque design. The necklace is encrusted with clear crystal rhinestones throughout, with the addition of stunning large ruby red rhinestones, both oval and teardrop/pear cut. 

The necklace is unsigned and I have yet to determine what company or designer was making pieces like this with these components and techniques. The closest pieces are by Attwood and Sawyer, but I have it on good authority that this is not an A&S necklace. Do let me know via message if you could identify it.

The necklace has an adjustable length up to about 16.5 inches and fastens with a simple hook clasp and rhinestone encrusted extension chain. It also has a slim safety chain to protect against the hook accidentally being pulled out of place - always a sign of quality. It is in very good vintage condition - all rhinestones present and bright, and silver tone good.
