Moissanite is one of the most durable gemstones available — but no material is indestructible. If your moissanite ring is damaged, the answer to "can it be repaired?" depends on what type of damage occurred and whether the damage is to the stone or the setting. This guide gives you the honest breakdown.
First: How Likely Is Damage?
Moissanite's Mohs hardness of 9.25 means it resists scratching from virtually everything encountered in daily life. Its fracture toughness of 7.6 MPa·m½ means it resists chipping from most impacts. In practice, moissanite is rarely damaged under normal wear conditions. When damage does occur, it is almost always to the metal setting rather than the stone itself.
Setting Damage: Fully Repairable
The most common form of damage to a moissanite ring is setting damage — bent prongs, a cracked shank (ring band), scratches on the metal surface, or loose prongs that allow movement in the stone. All of these are standard jeweler repairs:
- Bent or broken prongs: Re-tipping or full prong replacement. A standard repair at any competent jeweler.
- Cracked shank: Soldering or section replacement, depending on severity.
- Scratches on metal: Polishing. Restores surface appearance to near-original condition.
- Loose stone: Prong re-tightening. A routine maintenance procedure.
These repairs do not require specialist moissanite knowledge — any experienced jeweler can perform them. The stone is not touched during setting repairs.
Stone Damage: Rare, But What Happens If It Occurs?
If the moissanite stone itself is chipped or cracked — which requires a significant, direct impact at the right angle — repair options depend on severity:
- Minor surface chip on a facet edge: In some cases, a skilled gem cutter can re-polish the affected facet, removing the chip and restoring the edge. This slightly reduces the stone's carat weight but preserves it in the setting.
- Significant chip or crack: Re-polishing is not possible. The stone requires replacement. Under the Moissanite Shine Lifetime Warranty, stone replacement due to manufacturing defects is covered. Impact damage is evaluated case by case — contact us to discuss.
What the Lifetime Warranty Covers
The Moissanite Shine Lifetime Gemstone Warranty covers: stone loss from prong failure, structural defects in the stone's growth, and clarity changes attributable to manufacturing. It does not cover impact damage from accidents, loss due to theft, or normal wear to the metal setting. For complete warranty terms, visit our warranty page.
Prevention: The Best Repair Strategy
The most effective approach to ring damage is prevention. Have your prongs checked by a jeweler every 12–18 months — loose prongs are the primary cause of stone loss. Remove your ring during high-impact activities. Store it separately from harder objects when not wearing it. A ring that is consistently maintained needs very few repairs over its lifetime.
If Your Ring Is Damaged
Contact us first. We will assess the damage, advise on the best repair path, and where covered by warranty, arrange replacement or repair at no cost. For setting repairs outside warranty, we can recommend the appropriate service approach based on your ring's specific configuration.
