diamond
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.

Was mounted in a 2004 tacoma, but should work in any smaller truck. I bought this a couple years ago from Napa for 370. Don't really use so took it off. Like new, comes with mounting bolts and key. Asking 300 OBO and will consider trade or partial trade for ammo or gun.
Selling a classic 22lr rifle in excellent condition. This one is a Remington Nylon 66 22lr "Black Diamond" made in August 1981. The 66BD model is one of the lessor produced Nylon 66s. It has the black stock, blue/black steel barrel and receiver cover. I'd rate this one around 98%.

This little pocket rocket just sits in the safe so now I'm putting it up for trade. Has standard sights and only a couple of mags through it. Perfect for a summer carry or a back up pistol. Please send any...
Opened from box. practically new. They are polymer and only good for pistol length of rail which is around 10 inches. They work on a MCK but are better quality then the actual MCK ones. Maybe willing to trade try offering but I am mainly looking for the money that's 10 off the normal price.
I have this very nice revolver that I bought so I could go shooting with my husband, but I’ve only used it one time, so I’d like to sell it. It’s in great shape, and it comes with the original case and locks.
Briefly mounted on a 20" AR, but never shot. Just sat in the safe. I took it off and decided to sell.
Very nice audible clicks - no mushy turrets. First Focal Plane Scope, which means the reticle is correct at all magnification levels.
