This necklace-bracelet set is a combination of dark and light grey pearls with variegated black crystals.  The silver magnetic connectors allow you to connect everything together to create a 27" in a long necklace or separate it into a 20" long necklace and a 7" long bracelet that can be worn together or as separate pieces.
 
All metal used is hypoallergenic, nickel-free and either sterling silver, silver or gold plated or stainless steel unless noted otherwise in the description.  Every item is handcrafted and custom-made, nothing mass-produced.
