Watermelon Tourmaline Rough briolette Layering Silver Bangle Gemstone cuff minimalist Gem Bliss. A green and pinky red 10x7x6mm chunky Watermelon Tourmaline rough briolette has been caught between two fluted beads to grace the top of a medium to large Sterling Silver Layering Bangle bracelet. Tourmaline is an all time fave gemstone. These chunky rough briolettes, colorful, thick with dense color, are the latest addition to my year-end inventory supplies. Look for necklaces and earrings with more of these gemmy rocks, coming soon. You will receive the bracelet pictured.
