Earring posts follow a standard diameter convention across the industry, which means backs from different manufacturers fit most standard posts.
Stone Story
Tanzanite's lighting behavior is a measurable optical property, not a subjective impression. Its trichroic nature responds differently to daylight and incandescent light, producing a blue-dominant appearance in one and a violet-to-indigo shift in the other. Among major gemstones, very few demonstrate this degree of perceptible color variation across common lighting conditions.
Care & Keeping
A lost clutch back is easily replaced. Clutch backs are standardized fittings available in matching precious metals, and any jeweler or jewelry retailer can fit new ones to a standard-gauge post without modifying the earring.
