Selena Gomez might have teased her engagement manicure at the Chanel Academy Women's Luncheon on Dec. 11, but she saved the engagement ring itself for a dazzling Instagram debut hours later. The singer revealed she and producer Benny Blanco are engaged with a close-up shot of her new jewelry set on a pale pink backdrop.

The pop star sang about the exceedingly rare diamond shape in her 2015 song “Good For You,” nearly 10 years before her engagement.
