Custom Orders
On occasion, we take on custom projects by request. All custom work is final sale and not eligible for return, exchange, or refund. This includes engraved items. If you're interested in a custom piece, reach out to us first and we'll make sure every detail is right before production begins.

What's Not Eligible for Return

Defective Items
If your piece arrives damaged or has a manufacturing defect, contact us right away. We'll cover return shipping and provide a full refund or replacement at no cost to you — no restocking fee, no hassle.

Please note: Tarnish is not a defect. Sterling silver (.925) naturally tarnishes over time and simply requires occasional cleaning. This is a characteristic of the metal, not a flaw in craftsmanship.

Lost or Stolen Packages

If tracking shows your package as delivered but you didn't receive it, contact us at Sales@SeaShurJewelry.com immediately. We'll open a case with the shipping carrier (UPS or USPS) to investigate.

Once the carrier completes their investigation, we can offer a product replacement. We're unable to issue refunds for packages that tracking confirms as delivered.

Care Instructions

Why Does Sterling Silver Tarnish?

Sterling silver naturally tarnishes over time due to its reaction with sulfur-containing gases in the air, leading to discoloration and the formation of a tarnish layer. This process can also be triggered or accelerated by exposure to chemicals found in jacuzzis, chlorine, humidity, perspiration, cosmetics, household cleaners, and bleach. Moist environments can speed up tarnishing, so storing your silver in a dry place is recommended.

Tarnish can be easily removed using a rouge polishing cloth. Simply rub the cloth gently over the surface, and you’ll see the tarnish lift onto the cloth. The rate at which tarnishing occurs depends on the level of exposure to moisture and chemicals, factors that can vary widely between environments and individuals.

Why Might Your Pendant Tarnish Faster Than Your Necklace?

Many mass-produced sterling silver necklaces are plated with a thin layer of fine silver or rhodium to help prevent tarnishing during shipping and storage. Our pendants are not plated, so depending on what they’re exposed to, they may tarnish more quickly and require more cleaning compared to a plated necklace you may already own.
