1980s vintage Swarovski necklace

Flea market find. I bought this beauty last week, cannot remember now if for 1 EUR, or 2 EUR. I just liked the construction of it, and the unusual rhinestones in the front. Its gold plated, unfortunately the plating is damaged here and there.
Only yesterday I had time to check it closer and imagine what I thought when I saw this S... yesss... its old Swarovski mark. According to Illusionjewels this is the Euro mark Swarovski used until 1988.
