This necklace is an original designed handmade by Nautigirl252 Jewelry. This beautiful cork necklace is made with 2 strands of 3mm round cork in your choice of available colors. This necklace comes in 2 length sizes that are available and include a 1.5” extender chain to add to your length if desired. The large 55mm round circle pendant is a nickel free lead free and 💯 hypoallergenic and is plated in sterling silver with an antique matte finish. All other metal parts on my necklaces are 💯 stainless steel. Stainless steel will not rust or tarnish like silver and is a much stronger metal.
