The necklace is made of raw quartz crystal inlaid in a silver frame.
 
The length of the chain is adjustable: 49 to 56 cm.
 
Keep in mind that as the crystals in this necklace are natural, the pendants may slightly differ from the one showed on the photo.

Please let me now if you would like to see more photos of it, or if you have any questions. 
 
Yours, A.
