Adjustable chain with stars and green amethyst in 925 Sterling silver

Link necklace in rhodium-plated 925 Sterling silver with an approximately 8 x 12 mm drop-cut green amethyst from Brazil, two stars pavé-set with white zirconia above it and six approximately 3 mm round-cut white zirconia on each side. The ends of the two chain strands are also set with two zirconia.  The chain is adjusted to the correct length using a round stopper, which also bears the hallmark.  The maximum wearing length is therefore around 64 cm. The piece of jewellery cannot be opened completely; to put it on, the stopper is pulled back and the chain is then pulled over the head.
