This necklace, a bit reminiscent of the Cartier interlocking Love necklace, allows the buyer to personalize it for the wearer with names or dates.

By Merci Maman, the company describes it as follows: The interlinked circles will be engraved by hand with your own unique message showing how you two became one. Whether you want the personalised circle to represent the bond between mother and child, two inseparable lovers or long-time friends, the choice is yours. The two circles move freely between each other and as a result this is one of the few products where we engrave on one side only.
