We have taken a coin and hand cut the dainty heart, then the larger puzzle piece. You can still see some features of the coin as the custom pendants hang from a stainless steel chain. One of our family of 6 NameCoins friends will work on this for you.
We also can cut your personal initials or engrave names in each piece. This makes 2 necklaces that go together. Just let us know which initials you want on the puzzle piece and which on the heart. Usually the guy wears the girls initials and vice versa.
