This bookchain bracelet is solid 18K yellow and rose gold (NOT gold-filled!), a very wearable and versatile 7 3/4 inches long, and in perfect, original condition! The links are made of a rich yellow gold with a beautiful patina, with "book" panels of rose gold on top. Overall, the bracelet has a total of 18 links of an alternating pattern of stars (9) and diamonds (9), a classic victorian pattern, but most of these pieces are gold-filled, very hard to find in 18K. All the book panels are in perfect condition except for 2 tiny pieces of rose gold on the diamond-shaped panels (#3 and 8-- see photos). Width of bracelet is 11 mm (7/16 inch) and 6mm high.
