Maybe the reasoning behind the elevator brawl wasn't as deep as everyone suspects, because TMZ recently learned Solange and brother-in-law Jay Z were shopping for jewelry together earlier this afternoon.

Based on the way Solange was kicking and throwing jabs at Jay in that elevator, a happy reunion was the last thing foreseen in their immediate future. However, TMZ sources say the two were looking at women's jewelry, specifically gems,  for about 20 minutes in NYC at Mr. Flawless, with the owner himself.

Recent allegations, pigeonhole Rihanna as the root behind the unexpected flaring of limbs from Beyonce's younger sister. Solange apparently didn't want Jay to attend Rihanna's Met Gala after party without her big sis on his arm.

The estranged in-laws reportedly didn't say much to each other during the visit.
