The Piece of Heart and Heart Container from The Legend of Zelda - Ocarina of Time / Majora's Mask
These are for sale at my Etsy: [link]
Antique silver plated back cover with a glass plate attached to it. The included silver chain is also silver plated. All material is safe from nickel!
This is my own design, made in Photoshop and Illustrator. The pictures are printed in black and white on thick paper, then I use ProMarkers to color the line art.
I had to adjust the width and height of the heart a bit, to make it fit into the pendant
