I have also found a ton of what looks like Ram's Horn Oyster fossils as well:



This even appears to be a partial ammonite fossil.



Shark vertebrae are abundant as well if you keep your eyes open.





I also found some very nice Stingray (Myliobatis sp.)dental plates, these are really odd looking when you see them:




I havent found any tail barbs yet, but I am betting they are there too. There are even very nice corals to be found.



And of course shells all over the place.



The final picture is something I am still trying to identify, if you recognize it, let me know. I will post more as I find more.

The novaculite is perfect for toolmaking and in fact is quite common in the Magnet Cove area, however there is not any very close to where we were searching. This leads me to believe the indians were bringing it in and using it from a camp near the creek.

Here are several scraping or cutting tools I found while digging in the creek.



This looks a lot like an unfinished arrowhead.



I hope you enjoy the pictures, I found these to be very interesting finds.

Here is a pic of some of the guys digging in the creek...


This rutile specimen is about the size of a half dollar and and maybe a half inch thick. Obe Willix found one at least three times larger.



I also found an oddity, its a vary rare crystal form of iron pyrite (called a pyritohedron), in this case it was replaced later with limonite.



I also got excited when I picked up a small rutile crystal late in the day, but it wasnt an "eightling", however it was pretty close.



Well thats all I can post for now, however I did find some Indian artifacts during the rutile search and I will make that my next post!

1. Look for a small, well-rounded crystal. A diamond weighing several carats may be no larger than a marble.
2. Diamonds have an oily, slick outer surface that dirt or mud will not stick to, so look for clean crystals.
3. If you think you have a diamond, hold it carefully in your hand. Experience has shown once a diamond is dropped, it usually isn't found again that day.
4. Diamonds may be any of several colors. The most common found at the Crater are clear white, yellow and brown.
5. Bring any stone you think may be a diamond to the Visitor Center for free weight and certification. Anything you find is yours!

The park is located two miles southeast of Murfreesboro on Arkansas Highway 301.

These are all in or around Franklin.

The largest rubies are found in the Cherokee Mine on a consistent basis, but they are the lowest quality.

Medium size and quality rubies are found in the Sheffield Mine.

The best quality rubies are found in the Mason Mine (not Mason Mountain Mine), but they tend to be the smallest rubies in the area. This is also the only true "dig your own" mine.

Blue Sapphires can be found at the Chunky Gal Mine, they have an almost gray color, not gem quality, but usually very large.

Most rubies now found are not true rubies, they are actually pink to plum colored sapphires. Very few "pigeon blood" colored stones are found these days. Rutile inclusions cause the "star" effect in many of the specimens from the region.

The dirt is a thick red clay mix, it contains rubies, sapphires, iron garnets, quartz, kaolin, jasper and kyanite. You really have to work the "muck" over and over and "grind" the rocks together to knock off the outer crust of iron and clay to reveal the plum colored rubies. See the "muck" below...



I went through 12 buckets of Native Dirt and found just under 10 carats of Rubies, one of which went 2.5 carats and another 2 carats. See them below, and note they still look "dirty"..



As you will probably say to yourself, those don't look "red", well most of the rubies in North Carolina are actually "Plum" colored, or a lavendarish purple.
See more examples of rubies from the area that are not deep red.



Another closer shot of an example of a Cowee Valley non-gem quality ruby.




Here is a ruby from North Carolina, more red than most, but its in matrix and since the matrix has not weathered it would probably destroy the crystal to remove it, so I plan on making it a collection piece.



I did manage to locate a couple of the rarer "Pigeon Blood" colored rubies, one of which is gem quality and weighs about 1.2 carats, notice the red and not purple. Pigeon Blood colored rubies only come from North Carolina and Burma and are very desireable.



More interesting pieces, first a "Pigeon Blood" Burmese Ruby.



And an example of a "Star" Sapphire, which is basically a pink sapphire (rubies are actually red sapphires) with Rutile inclusions, that give it the shine in the stone. This stone has been finished into a cabochon (or "cab")weighing about 17 carats.



I'll post soon about the mines in the Cowee Valley and where you should go.

Aegirine is an inosilicate member of the clinopyroxene group. Aegirine is the sodium endmember of the aegirine-augite series. Aegirine has the chemical formula NaFeSi2O6 in which the iron is present as Fe3+. In the aegirine-augite series the sodium is variably replaced by calcium with iron(II) and magnesium replacing the iron(III) to balance the charge. Aluminium also substitutes for the iron(III). It is also known as acmite.

Aegirine occurs as dark green monoclinic prismatic crystals. It has a glassy lustre and perfect cleavage. The Mohs hardness varies from 5 to 6 and the specific gravity is 3.2 to 3.4.

It occurs in alkali nepheline syenites and similar igneous rocks. Localities include Mont Saint-Hilaire, Quebec, Canada; Kongsberg, Norway; Narsarssuk, Greenland; Kola Peninsula, Russia; Magnet Cove, Arkansas, USA; Kenya; Scotland and Nigeria.

Aegirine was named after Ægir, the Teutonic god of the sea. A synonym for the mineral is acmite (from Greek) in reference to the typical pointed crystals.
