The clutch back's dominance in earring closures isn't incidental. It meets a more demanding set of requirements than it sounds. It's compact, fits any standard post, and works whether the earring is a diamond stud or a long dangle.
Stone Story
Amethyst jewelry spans a broad color range, and the grade makes a visible difference. Pale lavender through mid-violet are the accessible tiers, and the most prized stones show a deep, even purple with rose and red secondary hues. The trade calls that top color grade Siberian amethyst, which is a designation based on quality, not origin.
Made With Purpose
A locking back, sold under trade names including Guardian and La Pousette, incorporates a mechanical lever or button that must be deliberately engaged to release the back from the post. It represents the highest standard of security currently available among post earring backs.
