The term ‘Peekaboo’ is used for stones that cannot be seen when looking head-on at the engagement ring, but only when you look at it from a particular angle (typically on the sides). 

Birthstones are the perfect peekaboo gem if you’re looking to personalize an engagement ring. 

Adding a secret birthstone is a lovely romantic gesture hidden in plain sight!
