I made a simple brooch out of agate and silver plated wire.
Rintakoru takaa. Otin kuvan vahingossa väärinpäin ;).
The brooch on the opposite side. I took a pic, accidentally, upside down ;).
If someone, who is making jewelry, is interested about these blue stones - I've more of them. Those sizes are 50x25 mm. I got them from Australia, quite much ;).
