This 18K yellow gold Foundrae Pyramid oval annex link charm is cast in the United States to a delicate 6.5 mm circular shape. Decorated with triangles along the outside, it clicks open and closed so you can fasten it to chain earrings, or use it to add to your favourite necklace. The Egyptians might have created the pyramids, but we think this Foundrae link might have beat them in ingenuity.
