Our guarantee covers any manufacturing or structural defects in the metalwork and settings of your jewelry. If your piece experiences a fault due to a crafting flaw, we will repair or replace it at no cost to you. It also includes Complimentary Lifetime Cleaning, Polishing & Inspection, which covers professional cleaning, polishing, and comprehensive prong and setting inspections to ensure the structural integrity of the piece.

Our craftsmanship warranty does not cover:

• Normal Wear and Tear: Gradual thinning of metal, worn prongs over time of daily wear, or scratching, chipping, fracturing of the gemstone itself once it is in your care.

• Accidental Damage or Trauma: Physical impact (e.g., dropping the piece, crushing a band, catching a prong on a hard surface) or exposure to harsh household chemicals.

• Loss or Theft: The warranty does not cover the loss of the jewelry piece or the loss of a major center stone.

• Third-Party Alterations: Any work performed by a jeweler outside of Stark Jewelers immediately voids the warranty.

High-end, bespoke jewelry is engineered with incredibly precise tolerances. When a piece is resized or altered, the metal must be heated and manipulated.

• Outside jewelers may use incompatible metal alloys or lower-carat solders, creating micro-structural weak points that didn't exist when the piece left our studio.

• Altering the band changes the structural tension holding your diamonds and gemstones. If an outside jeweler resizes a ring without meticulously retightening every single accent stone, those stones will become dislodged.

To maintain our strict standards of excellence and protect your investment, we require that all alterations, resizings, and repairs be performed exclusively by our master jewelers.

We recommend bringing your Stark Jewelers pieces into our studio every six to twelve months for a complimentary professional cleaning and safety inspection. Our master jewelers will inspect the prongs, settings, and stones to ensure everything remains perfectly secure.

We take full responsibility for the masterful setting of your gemstones at the time of manufacturing, meaning they are structurally secure when they leave our studio. However, our warranty does not cover the natural degradation, scratching, chipping, or fracturing of the gemstone itself caused by everyday wear or external forces.

Because gemstones are natural materials, they have inherent geological properties:

• Even a diamond, the hardest natural substance, can chip or cleave if struck at a precise angle against a hard surface.

• Softer or more porous gemstones (like emeralds, opals, and tanzanites) can naturally dull, scratch, or erode over time due to contact with everyday surfaces, cosmetics, and household chemicals.

Because the physical degradation, accidental fracturing, or theft of a gemstone is not covered by a craftsmanship warranty, we strongly advise acquiring dedicated jewelry insurance. This ensures your financial investment is fully protected against accidental damage, catastrophic loss, or theft.

Yes. The Stark Promise applies to any piece designed, crafted, or serviced in our studio. When we perform a repair or alteration on an existing piece of jewelry, we stand behind the specific work we performed. If a setting or repair we executed fails due to our craftsmanship, we will correct it immediately at no charge.
