This necklace is made in sterling silver and bronze. As shown in the pictures you can wear the necklace as a bracelet also. The eggs collection is inspired by a curious story: An egg of Columbus refers to a brilliant idea or discovery that seems simple or easy after the fact. Using only one shape, Microfficina created a very large number of different jewels that you can wear in many different ways. The first piece was made directly in metal by hand; later I produce other specimens by casting. Since the jewel is handcrafted the final product may differ slightly from the picture. Each jewel is shipped in its packaging. Handmade in Florence.
