The Swarovski beads are machine made and put together mostly in China, so we have a situation the same as Waterford Crystal.
Both are marketed on their name, not on the products. Waterford's quality was not very good and had a lot of flaws and bubbles as they were handblown and it is almost impossible to control this issue when crystal comes from a furnace via hand.
Swarovski uses small beads mostly, and it is very difficult to see any flaws, but they do not produce any better designs than any Chinese producer does. They use the same products, but Swarovski may have a more skilled design department. I think it is a bad choice for investment.
I have my own crystal studio, where we make almost anything in crystal and I have very skilled craftsmen. We can also make design ideas at very moderate costs. (not inflated as Swarovski). We also concentrate a lot on the corporate awards industry and we engrave logos and any inscriptions.
