This necklace definitely has some weight to it, and the stones are truly eye-catching with the shimmer they give off. Made by Bocar. Lobster clasp with extension spacing on end of necklace. Measurements: Necklace length: 20”, extension 2.7” weight: 2.8oz Material: Natural agate stone beads in a type of titanium coating that gives it its iridescent coloring. I believe the chain is silver plated nickel. I am unsure what the spacer beads, clear beads, and dark beads on the chain are made of. Condition: VEUC [Very Excellent Used Condition] - minor scuffing around the spacer beads and darker beads along the chain - could use a bit of a cleaning - otherwise in great condition Disclaimers: - I ship all jewelry and vintage AS IS. Different buyers have different preferences when it comes to cleaning and repair work. - I wrap all fragile items and jewelry as best as possible to preserve them from any further damages during shipping. I also use a lot of recycled plastic for the packaging to reduce waste. As a result, the packaging is not going to the prettiest, but it is going to keep the item secure during shipping and transit.
