This is a sterling silver pendant set with a smooth pink Tourmaline cabochon stone. (A cabochon stone has a domed top). Tourmaline is one of two birthstones for people born in October, Opal being the other stone. This tourmaline is a lovely mid rose pink. The textured silver pendant is made from two oval shapes which have been soldered together, one on the vertical and one on the horizontal. The ovals have been hammered with the rounded end of a ball pein hammer to give texture and to reflect light. The pendant is suspended on my hand made silver bail and is hung from an 18 inch fine oval belcher chain which is detachable from the pendant. Dimension: Drop Length: 32mm from the top of the bail to the bottom of the setting. Width: 19mm at its widest point. Width of wire used to make the pendant: 1.50mm. Diameter of Tourmaline: 4.6mm. The pendant has been made with 100% recycled sterling silver. Hallmark: To comply with the UK Hallmarking Act 1973, all items made from Sterling Silver require a hallmark if they weigh 7.78g or over. As this pendant weighs under this and is detachable from the chain, it is not hallmarked. The pendant comes in a box with an anti tarnish foam/velvet insert. A small silver cleaning cloth is also included to help get you started in keeping your pendant shining.
