I have set a 20 mm x 10 mm Dendrite Agate and a dark red 10 mm x 8 mm Natural Ruby into a fine silver setting.

This small pendant measures 1.25" by 1" and hangs from a sterling silver chain.
 
 
Please be aware that the size of jewelry in photographs can be deceptive so be sure to read the measurements carefully before you purchase.
 
 
I design and make all of my jewelry in my home studio in Texas.
