Three families tell their stories on video.
In an act of profound love and remembrance, Mercier decided to encapsulate her husband’s essence in a diamond, crafted from his ashes.
No matter how happy or sad Mrs Leung feels, her husband will always be there for her. She wears her memorial diamond every time she goes out.
At eleven or twelve, when they had to say goodbye, they made a promise: if they still loved each other after ten years, they would be together.
“Over the past few years, I’ve grown used to travelling with my memorial diamond. It’s a wonderful companion, and with it I don’t feel alone.”
“We placed the diamond in our living room, and since then the memories of my dad have always been with us. In a way it comforts us, and it has truly helped us move on while keeping all the wonderful memories close. This memorial diamond is something we truly appreciate.”
“After receiving my memorial diamond, I have always worn it around my neck. From the moment I put it on, I felt more at peace. Every now and then I touch the diamond at my neck, as if I were talking to him.”
“When I received the ashes, my heart ached… When I saw the memorial diamond, my heart felt warm. Now, whenever I feel worried or afraid, I look at my bracelet and feel steady again.”
