This beautiful gold necklace from Qudo is compatible with the interchangeable Qudo toppers. Style: Sezze Necklace Length: 40cm + 5cm Material: Gold Plated Stainless Steel Comes with authentic Qudo packaging. We wouldn't recommend a topper bigger than 11mm for this necklace. Any bigger and the topper makes the fitting top heavy, causing the necklace to fall forward.
