We utilize FedEx for shipping our products. Typically, delivery times range from 4 to 7 days for most destinations where our jewelry is shipped. For further details, please refer to our shipping policy. Should you have any inquiries, feel free to contact us via email at

We provide a lifetime guarantee on the quality and craftsmanship of our products. However, there are two conditions that automatically void our guarantee:

  • If the piece has been manipulated by anyone other than our own craftsmen, the guarantee is nullified. Our technique is highly unique and not commonly practiced by most jewelers and goldsmiths. Any external manipulation compromises the integrity of our craftsmanship.
  • The guarantee does not cover damage resulting from harsh wear and tear conditions. Even the most durable metals can succumb to damage when exposed to chemicals or subjected to high-force mechanical impacts.

Additionally, certain services are not covered under the free lifetime guarantee, such as resizing after 90 days from the shipping date and customized engravings. However, we can provide separate quotations for these services. If accepted, we can proceed with resizing, engraving erasure, or adding new engravings as per your request.

For more detailed information, please refer to our Guarantee page.
