Hallmarked Sterling Silver ‘Spinning Sphere’ Milky Quartz 17” Fidget Necklace

I have teamed up my spinning sphere pendant with my short length dot dash chain to make a choker style necklace. 
The setting of this gemstone marble sees the silver moulded just around the middle of the marble. This allows the marble to moves freely within the frame but is held very securely so won’t fall out. It’s very tactile with plenty of movement. 
The sphere in this necklace is a Milky Quartz and is 16mm in diameter and is permanently attached to the central point of the chain which is a total of 17” long end to end. 
The chain is completely handmade from forged sterling silver wire which is 1.5mm thick and comprises of alternating long and round links. The long links are roughly 33.4mm x 6.5mm. The necklace is assay hallmarked on the disc near the clasp which is also handmade. The necklace weighs a total of 28g. 
The necklace will be sent in my signature gift box.
