Our authentication is centered around prehistoric flint and stone artifacts from the general Midwestern US area. We do not authenticate artifacts from outside the US. We also do not solicit to authenticate artifacts that are made from pottery or shell.
We base our conclusion on the evidence that is found on the artifacts surface as well as how the artifact itself was manufactured. If an artifact has been in the ground for an extended period of time, it should have evidence of such. Mineral deposit and patina are a couple things we look for, but also how the artifacts surface “weathered” while it was in contact with the surrounding soil, sand or water.
If you provide us with an email address on the Artifact Submission Form, we will email you when your package arrives at our facility. If you do not have an email, we will call you to let you know the items arrive. Once the evaluations are done, we will email or call you to let you know the results of the evaluation. If you have email, we will email you the tracking number on the return package.
Knowing that most collectors and dealers would like their artifacts evaluated and returned as soon as possible, we try to process every package in a timely manner. Usually our turn-around-time is 2-4 weeks. For large authentication projects, more time is needed simply due to the time it takes for each inspection.
Most times artifacts will have the evidence needed to make a decision of real or reproduction. However, there are situations where an authentic artifact may not display enough positive traits to make a decision, or a reproduction may not display enough negative traits. In these situations we do not issue a COA or a Rejection Letter, and the full amount of the service fee is refunded.
