This necklace is so versatile. It is not marked but tests positive for sterling (acid test). The belcher chain is just lovely and the total length of this necklace is 49 inches. The crystals are faceted and are just under 3/4 of an inch long. They are topped with channel set blue square pastes. The chain is in very good condition. The clear crystals have several flea bites from decades of banging against each other, they are not too bad, and there are no chips or cracks that I can see. One acorn has has several blue pasts replaced and both have dings to the metal. C. 1925 and English in origin.
