Dendritic agate is one of our favorite stones to work with because each piece is truly one of a kind. This necklace is a serious stunner: The agate is set in an 18K green gold bezel with our Temple charm and and signature locking clasp in 14K green gold. We like to wear this statement piece a little bit longer so the chain is 21". The agate is 4cm long and 2.5cm wide.
