These are nice Swarovski crystal channel set stones, just out of of storage. Most are about 34 SS stones and that is about 7 mm measured on the outside of the setting. Double Eye is bigger as you see. You get 100 per lot. All same color both sides accept the blue opal which is a hematite look on the reverse. These are sold as a random mix color lot. The high bidder gets 100 pieces, also have other sizes. These are soooo nice, you will be very pleased. Please check our other auctions here and at debsbeads on ebay for more vintage swarovski and other natural stones. Thanks, Pete
