This shows off an outrageously sensuous minimal surface which is called the Chen-Gackstatter surface.    (It's like an Enneper surface with handles.)  In this model, two Y-shaped parts thread through it, giving an irresistibly clicky feel, and pointing up its topology.  This compares interestingly with the Costa Handshake pendant.
