We are rebuilding.  The "Original Site" will be left intact until all its contents have been moved into the new one.  It will then be no longer available.

 
 

   This website is devoted to those of us who collect, study, or otherwise enjoy the beauty and diversity of one of the World's great minerals, CORUNDUM.  We welcome you to come in and browse, and we especially appreciate your helpful suggestions and contributions as we continue to develop this never ending "work in progress".

Corundum is an economically important mineral, being the basic substance of both ruby and sapphire, as well as emery abrasive.  It also occurs in nature in a variety of attractive forms, and is found in surprisingly many different localities.  This great diversity is what motivated us to assemble the collection and make the information available to all who share the passion or need to know.

We hope you enjoy the pictures of specimens from our collection of nearly three thousand specimens, as well as others we wish we owned.  We also have articles (many by guest authors) on science, geography, and history which vary from introductory level o extremely arcane.

Navigation within this website is through hyperlinks, all of which are interconnected in "general to specific" order as shown in the tree below.  You may also click on any hyperlink in the tree and get to the page directly; or from any of them, back to the tree.
