The Edelweiss flower logo was symbolising Austria, alpinism and purity. The block SC logo was used from 1976 to 1988, after which Swarovski decided to continue with the now infamous swan logo…. There are even some pieces on which you cannot find any logo, but are still genuine Swarovski.
What is the Swarovski symbol?
The Swan logo was the Swarovski logo that replaced the block SC logo used on the Silver Crystal product line. Swarovski began using the swan logo in 1988 and still uses a swan logo today. Crystal bearing the Swan logo means that the crystal was produced 1988 or later.
