The Low Tide ring is inspired by the movement of waning water. Hand carved and cast with a high polish mirror finish. Materials: Brass A note on brass rings: The copper in brass rings can react to your ph levels, body sweat, and lotions, causing the area where the ring rests on your finger to turn green. This is harmless and natural. You can apply clear nail polish on the inside to act as a barrier between the metal and your skin. Keep your hands clean, dry, and remove pieces when washing or applying products to keep your ring looking its best.
