"I feel like this exact moment will be etched into my memory forever," Blanco wrote of the romantic moment that followed the black-and-white shot

The singer gave away an ultra-rare ring for an ultra-rare price as part of promo for her upcoming album with fiancé Benny Blanco.

While Gomez will no longer have her "B" ring, she's probably just fine without it considering the major upgrade she got recently. In December, Gomez revealed that she and Blanco are engaged. Her marquise diamond engagement ring has been estimated to be worth around $250,000.
