Each pair is unique, but so beautifully matched (bookmatched) that I just can't bear to break up the sets. To get stones matched like this, they have to start with a very thick piece, and then slice it down the middle lengthwise - a tricky business to do. You will probably have to come into the store to pick yours out, unless you want to just go for it and see what you get. Size is approx.
15mm x 35mm Hole is front to back. By the pair.
