"If it ain't XO, then it gotta go."

Those were the words posted by celebrity jeweler Iceman Nick after he visited with The Weeknd, Belly, NAV and Amir "Cash" Esmailian to hand out some sweet custom jewels for their respective collections. Making up the XO brand, those four were in Houston for a stop on the Starboy Tour at the Toyota Center.

The Weeknd showed off his new chain via Iceman's Instagram, holding up an all-gold piece that looks quite detailed and intricate. Meanwhile, the jeweler showed off a custom "XO" pendant and a similarly diamond-encrusted chain, presumably that go together as a set. Though it's not obvious who that item was destined for, the swag level was kicked up a few levels regardless.
