Hello! Do you have a question? Please, email us! We hope to increase your knowledge about Herkimer Diamond crystals through the information on this site.

Herkimer Crystals Online is a small business located in Berks County, PA, USA. After several years of mining these unique crystals, we have decided to offer some of our collection to like-minded persons in the International Online Community.

All crystals pictured throughout this site are in their "natural" form. That is to say, Mother Nature created the facets and brilliance of these gemstones millions of years ago. I would also like to note here, if any crystals have been reconstructed, a note will be placed on the detailed page of the stone.

The Herkimer diamonds displayed have been categorized by 'grades' - AA to D grade and more. AA grade stones are the 'cream of the crop'. D grade stones are pieces and points of Herkimer's. The page labeled Matrix has beautiful cabinet specimens. There are some Herkimer crystals so unique we are unable to grade them. It is these stones that will be listed in the Atypical category. The newest addition to the website is the Jewelry page!

Our stones are attractive to a large audience. Rock collectors looking to add a new specimen to their collection (in gem and matrix form) as well as jewelry makers searching for that brilliant gemstone for a project. Those of you interested in the metaphysical will appreciate the many unique properties these quartz crystals provide.

All Herkimer Diamonds pictured are the crystals you are purchasing. We hope you enjoy viewing the pictures of these gemstones and learning about Herkimer crystals, and we hope to hear from you!

Thank you for your interest,
Kimberly & Rich
