Our Bubali sea glass earrings pay homage to the beautiful Bubali Bird Sanctuary in Aruba. The earrings were lovingly handmade without any harm to the earth. The glass (art glass, antique glass, or repurposed glass) was tumbled in the same manner it would be in the sea, without polluting. The metal used is called Harmony Metal, which is recycled (not mined) sterling silver. Feel good about adding this eco-friendly bijou to your wardrobe for that island-inspired look.
