That's a unique collar made specially for a friend's birthday. For me that's the most beautiful pice, I've ever designed. The collar is made of tens of original Swarovski cristals (Briolettes, Teardrops, Bicones), onyx, Swarovski pearls, glass flowers, blackstones and quartz on the sterling silver (925) chain. Not for sale. It's priceless ;) If you'd like to have a simillar one for yourself, prepare 60 €.
