At first glance, this looks like a regular red heart-shaped pendant. However, upon closer inspection, you will see that there is an interesting texture inside the glass. The shade changes depending on the angle from which you look. It is made of hand-blown borosilicate, which is one of the most durable types of glass. The pendant also comes with a hole on one side for a standard neck chain. As with my other glass creations, this piece is kiln-annealed in my studio.
