925 Silver and Blue Stone Dangle Earrings

This is a pair of 925 silver (hall marked) and oval cabochon shaped natural blue stone dangle earrings. They may be lapis lazuli but I am unsure of their exact composition. They swing from shepherd hooks and so are for pierced ears. They hang down approximately 1.25 inches from top to bottom and the stone is about 1.2 by .8 cm in dimension. They look to be a dark navy in the photos but are actually lighter blue in person: a dark denim blue is closer to their true color. They are light in the lobe for all day wearing comfort and are in excellent new like undamaged pre-owned condition.
