Diamond is a solid form of the element carbon with its atoms arranged in a crystal structure called diamond cubic. At room temperature and pressure, another solid form of carbon known as graphite is the chemically stable form, but diamond almost never converts to it. Diamond has the highest hardness and thermal conductivity of any natural material, properties that are utilized in major industrial applications such as cutting and polishing tools. They are also the reason that diamond anvil cells can subject materials to pressures found deep in the Earth.
Because the arrangement of atoms in diamond is extremely rigid, few types of impurity can contaminate it (two exceptions being boron and nitrogen). Small numbers of defects or impurities (about one per million of lattice atoms) color diamond blue (boron), yellow (nitrogen), brown (defects), green (radiation exposure), purple, pink, orange or red. Diamond also has relatively high optical dispersion (ability to disperse light of different colors).
Most natural diamonds have ages between 1 billion and 3.5 billion years. Most were formed at depths between 150 and 250 kilometres (93 and 155 mi) in the Earth's mantle, although a few have come from as deep as 800 kilometres (500 mi). Under high pressure and temperature, carbon-containing fluids dissolved minerals and replaced them with diamonds. Much more recently (tens to hundreds of million years ago), they were carried to the surface in volcanic eruptions and deposited in igneous rocks known as kimberlites and lamproites.
Synthetic diamonds can be grown from high-purity carbon under high pressures and temperatures or from hydrocarbon gas by chemical vapor deposition (CVD). Imitation diamonds can also be made out of materials such as cubic zirconia and silicon carbide. Natural, synthetic and imitation diamonds are most commonly distinguished using optical techniques or thermal conductivity measurements.
Got back last night from our “Rat” hunt with Diamond A out of Burns, OR and what a blast, literally.
Right off the bat, we drove in and @flashpan got us settled into our tent and made sure that we had everything that we needed. Diamond A is a first class operation and he definitely made us feel...

Cleaning out My closet to hide presence and found this little gem. Let people know how much you love heavy metal with this case.
I purchased this case years ago for a project and never did it New fresh foam and practically brand new!
It fits a Mossberg 590 and whatever is smaller.

Diamond by Bowtech Deploy SB R.A.K. compound bow. This bow is new/never used (never shot or dry fired) and has never had any adjustments made to it (set up for personal use). My wife got this in April of 2016 but has not been able to use it due to Carpal Tunnel surgery on right wrist and...
This rifle is slightly used and in excellent condition. For priming it takes #11 or musket percussion cap or #209 primers. Barrel is 1/28" twist and it has True Glow fiber optic sights. Drilled and tapped for scope and is stainless steel.
BlackOut S3 Compound Bow Package - Used bow, excellent shape. Bought a new Hoyt, so this needs to go. Fast and aggressive, this bow is built for hard-hitting speed. I have a G5 headloc quiver on it, Truglo 5 pin sight, hostage rest and a Limbsaver LS Hunter stabilizer installed. Also comes...
A nice shooting Nylon 66. This one has some surface rust, so most likely not for the serious collector. But a nice vintage 22lr rifle that many of us carried as kids. I am looking for something that shoots .22 shorts, so if you have a trade for a lever action or tube fed bolt I'd be...
