For the drop there is a large oval gemstone with small bicone Swarovski crystals on a long headpin. Attached by a small jump ring is a 4mm round gemstone and attached at the bottom is a large Swarovski crystal.
The necklace has a pattern of small bicone crystal, 4mm round gemstone, Bali tube spacer, gemstone and large bicone crystal. That pattern pretty much repeats around the whole necklace.
