We have taken a coin and cut it into a puzzle piece and then cut a heart from the middle. We also hand cut 2 initials 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 names and vice versa. All of our jewelry is cut by hand and by us in our workshop. We have a great team of 6; all of us care deeply that you get exactly what you want and something that you will love for years. We have very smooth and sturdy stainless steel chains and key chains.
