Loose Stone or Diamond? Tightening & Replacement Guide
How much does stone tightening cost?
Tightening a loose stone typically costs $10–$25 per stone in 2026, depending on the setting type and whether prongs also need retipping. A loose stone is usually a worn-prong problem, not a lost cause — acting early prevents losing the stone. Every RJS repair is quoted first and insured under a Lloyd's of London Jewelers Block Policy.
Why stones come loose
- Worn or bent prongs (most common)
- Impact or daily wear loosening the setting
- Shrunken or damaged bezel/channel walls
How stones are secured
A bench jeweler re-tightens or retips prongs, reworks the bezel, or resets the stone. If a stone is chipped or the setting is failing, replacement or a new head may be recommended.
