Now they are usually bought offline from Swarovski stores. The only thing you can buy online is the MBOX music box. Their store is the only one that cooperates with Swarovski Element Company. And obtained the brand authorization of swarovski elements. Nothing else is reliable.
According to industry rumors, Swarovski and MBOX will cooperate to open an independent Taobao Mall to sell Swarovski elements. I believe the price is also high. But at that time, you can check the world unique number of each product in Swarovski official website.
If you buy it now, you can only buy it in Taobao flagship store of MBOX, and you can buy genuine products.
