News and Comments

The Internet and web sites started to reach the general population in 1996 (sparked by the innovation of web browsers that could display HTML web pages). As a result a large percentage of the content available for references via the Internet date after 1996, with the exceptions of institutions that are posting archives of earlier printed material.

For the mineral collector there are few online references to minerals with older mineral finds., and even my Online Mineral Museum largely represent minerals found after 1996. Yes, there are older minerals on the Internet that came from collections that have been dispersed since 1996, but they are small percentage and often lack historic references.

Just compare the number of cubic magnetite specimens available in online reference sites from 1991-1992 find at ZCA Mine No. 4, 2500' Level, Balmat, New York ( has 44 specimens illustrated) to the number of a similar find of more recent times like the prehnite pseudomorphs after anhydrite recovered in ten years ago at Lower New Street Quarry, Paterson, New Jersey ( has 125 specimens illustrated). The former find was much larger, but because it predated the Internet, while the latter was widely dispersed through online mineral dealers, fewer photos are available of the older/larger find on Mindat.

(My Online Mineral Museum has 100 cubic magnetites illustrated.)

So if you are a serious mineral collector, and want to research an older site or minerals collected before the Internet, where can you go?

It means you must use a book.

  • If you want to research high-end, fine minerals then you need books like The World's Finest Minerals and Crystals by Peter Bancroft, the book The Desmond Sacco Collection by Bruce Cairncross, or the book The F. John Barlow Mineral Collection by John Barlow.
  • If you want to research gems and gem minerals then you need books like Gem and Crystal Treasures by Peter Bancroft, Gems & Crystals by George Harlow; Emerald and other Beryls by John Sinkankas, or the many monographs produced by Lithographie.
  • If you want to research specific minerals or mineral groups then you need books like Zeolites of the World by Rudy Tschernich.
  • If you want to research minerals from specific localities  then you need books like The Mineralogy of Maine, The Minerals of Mexico, The Minerals of the Carpathians, the Mineralogy of Arizona, The Minerals of South Africa, Minerals and Precious Stones of Brazil, etc.

Every collector should have a basic reference library with books about their special interest. If you do not have a special interest, then you need ALL of the references above. You cannot rely solely on the Internet.

The good news is that many mineral clubs have reference libraries available for their members. (Do you really need another reason to join the local mineral club? Do it today!) Local universities and colleges and even some public libraries have these books. And lastly, because books in print are not as popular as in the past, many can be purchased for pennies on the dollar via used book dealers one ABE, Ebay, or Amazon.

Customer Comments:

"Once again, thank you, the crocoite is perfect and the analcime, calcite and quarts on prehnite is exactly what I wanted.I love your site and all it has to offer. You re the best." Tiffany V.

"I love the fluorite from Tennessee my husband got me for our anniversary. It is everything I wanted in this beautiful fluorite. Thank you for getting it out as quickly as you did. "

"We received from you a specimen of Pyromorphite from Phoenixville. It has got to be the most magnificent specimen of this species we have ever seen. The photos on your website did not do it justice." M. Martin in UK.

"Some months ago, we asked if you could obtain for us a specimen of Fluorite from Illinois. We left you to it knowing that sooner or later you would come up with the goods. And you certainly have. It is an absolute magnificent Fluorite and we can't thank you enough for going to all that trouble to obtain it for us." Marie...

"Thank you John! I just added two nice Diamonds from the North Cape Province, South Africa to my collection. John's service is impeccable! My new prized specimens were described honestly and photographed perfectly. I am a very happy collector! For everyone seeking to buy collection grade (or jewelry grade) Diamonds, John Betts fine minerals in New York is the place to go!" Michael P.
