About Costco Jewelry
Costco sells only finished jewelry. No loose stones or semi-mounts are available online or in our warehouses. The majority of our jewelry is available in either 14kt gold, 18kt gold, or 950 platinum, with some items being available in stainless steel and silver. We are unable to customize jewelry or metal preferences beyond what is offered for a particular item. Costco does not clean or resize jewelry. Some of the jewelry items offered online may also be available in warehouses.
Purchasing Jewelry Online
The majority of jewelry items offered online are shipped, insured, with items of $500 or more requiring a signature upon delivery to your home. Costco.com items are not available for shipment to warehouses for preview, prior to purchase. Gift Messaging will be made available during the checkout process. If you'd like to keep your purchase a surprise, consider choosing the Warehouse Pick Up option at checkout.
