Sterling silver is a legally defined alloy of 92.5% pure silver, governing fine jewelry and silversmithing for centuries, which makes the authenticity question both settled and well-documented.
A Notable Quality
Cubic zirconia's density is measurably higher than diamond's. A stone of identical cut dimensions will register approximately 70% more mass on a scale. In a large CZ piece, that additional density is perceptible in the hand. It's one of the few tactile distinctions between the two materials that doesn't require optical equipment to detect.
Made With Purpose
For drop earrings, a leverback offers more positive retention than a clutch back. The leverback creates a locked closed loop through the piercing, while the clutch back relies on spring friction gripping a post. Friction backs are designed for posts, not hanging wires, and the difference in security is meaningful.
