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!
Here is a list of birthstones according to each month of the year, that will help you pick the one fit for your significant other:
June: Pearl or Alexandrite
October: Tourmaline or Opal
November: Topaz or Citrine
December: Tanzanite, Zircon or Turquoise
