Fantastic Vtg Art Deco German Pink Lavender and Green Rhinestone Necklace Czech?

Description

This necklace is done in shades of pink, yellow, green and lavender.  The stones are pressed in and necklace has a series of open back stones that lead up to a chain that has a spring ring clasp. The stones look like there is literally a fire inside them unlike many that I've seen. There is a series of three round faceted stones like a trefoil with a marquis cut lavender stone dangling from that. The colors in the trefoil are pink green and what looks like a pale yellow. I am unsure of the metal but needs cleaned. It's marked "Germany" on the clasp. I believe the stones could be the old czech.  Now, the bad, there is a lavender marquis dangle that is missing, see photos.  Also there is a pendant attached which looks like something else was attached to it and is attached by a "jump ring",  again, see photo.
Honestly this is the nicest rhinestone necklace of costume jewelry I have had in my possesion. The craftmanship and quality is amazing! Although I know it has flaws, it's something special and I hope this catches the eye of a jeweler who will be able to take this back to it's former glory. Necklace measures 21" long.
