This lovely necklace stamped APM Monaco has only been worn a couple of times so is in very good condition.  The heart measures approx. 1cm x 1cm and this has a banded green centre (possibly Malachite) which is surrounded by tiny clear crystal stones.  The loop the chain slides through also has a band of tiny clear crystals.  The chain slides well through this loop which is signed APM Monaco as is the back of the heart.   Each side of chain measures 32cm.  The chain does tend to "twist" but can easily be straightened, this is possibly due to being stored for a time.  Please study the photos for more details as to condition etc.
