40 Common Minerals - Tungsten, Silver, Feldspar & more!
I just wanted to say that, as a science teacher, I have been using your page with information on rocks and minerals (http://www.dendritics.com/scales/gem-links.asp) for my lessons. It's been useful; thank you for making it!

Since your page was helpful to my classroom, I thought I would pass along another resource one of my students found that you might like to include: "40 Common Minerals - Tungsten, Silver, Feldspar & more!" - http://www.larsonjewelers.com/40-common-minerals.aspx

It lists 40 common minerals and their uses, making it a handy reference guide. I thought your visitors might find it beneficial too. (Plus, I would love to show my student that the page he found is incorporated on your website...makes him feel special, haha!) Hope I could help!

Happy Holidays, Ms. Sarah Hess

Robert J. Williams, Ph.D.,G.G. ... Rockhound, Jewelry, Appraising
Retired appraiser of Antiques, Gemstones, and personal property, Author of program Gemstone. The program covers over 650 minerals, and all gemstones. It is a compilation of formulas, data, and instructions for gemologist, mineralogist, and jewelers. Supplied information for The bench jeweler and appraiser as well as for the rockhound: the specific gravity, hardness, crystal system, refractive index, luster, fracture, cleavage, color, and chemical formula. Much of the basic data used in the Dendritics Automated Calculations page is courtesy of Bob Williams. Unfortunately, he has disappeared from the Internet.  I fear he is dead.  A great loss to the gem world if true.  If you read this, Bob, please do contact me (dead or alive).

Marian's Paintings.
Life is food, art is life everlasting. A fullness in your belly and a relief in your soul. As Marian Dioguardi, artist, says: I am an independently trained painter. My favorite teachers are Ed Stitt, Janet Monafo, Paul Rahilly and Barney Rubenstein, who have all contributed to my training. I paint still moments inspired by simple beauty in a simple way. I am a purist. Paint, panel, pallet knife. I am challenged by color and contrast, form and shape and the way in which objects occupy two-dimensional space.
