Policy Audit

What most jewelry retailers don't publish before you pay

We read the fine print across 20 major jewelry retailers so you don't have to. Here's what we found on deposits, warranties, returns, and what happens when something goes wrong.

At most retailers we reviewed, there is no written policy explaining what happens to your deposit if a custom order falls through.

Some of the biggest names in jewelry retail publish no rules at all governing custom order disputes, at any stage of production.

At more than half the retailers we reviewed, your warranty is voided the moment any other jeweler touches your ring.
