Tumbled sun agate "spikes" with matt grey hematite spacers and finished with an oval Rolo Sterling silver chain and S-clasp for comfort at the back of the neck.
The agate has some interesting stipes and swirls and a few sections have druzies.
The length of the necklace including chain is 67 cm,  consisting of 40cm of stone and 27 cm of chain.  The S-clasp can hook over any of the chain links so the necklace can be adjust to sit perfectly on your neck.
Its a striking piece.
