Return Policy

We guarantee our products. We strive for the highest academic research and jewelry production standards. The dimensions of an item and the materials that it is made of are carefully listed. If an item hasn’t met your expectations, you may return it. The complete cost of the item will be refunded, but not the shipping. If an item is damaged during shipping, please contact us immediately so that we may come to a mutually satisfactory arrangement. An item may be returned for exchange, refund, repair, or credit.

If you have any questions about our guarantee, please, email us at guarantee@eirny.com.

Returns and Exchanges

Returns and exchanges may be made by mail. Please call or email us if you wish to return or cancel an order placed online.
