This can be quite tricky. If it's too clean, too sharply formed, be a bit suspicious. They form in mica, so rough faces and rounded edges are the norm. Look for saw marks or bubbles, in case it was formed by cutting or casting. A low power microscope reveals a lot. Experience is the best teacher; if you've seen a lot of them the fakes will become obvious.

The Dome of the Rock is not really a rock, but a shrine in Jerusalem, Israel.

A jeweler.

Three (3) rocks in the rock cycle are sedimentary, igneous, and metamorphic rock.

The value of gold depends on it's purity; the price of pure, 24k gold is set daily by the metal markets.

Alaskan gemstones include nephrite jade, rhodonite, quartz in several colors, garnet, mammoth ivory, gold in quartz, and even a few diamonds. It's a big state, very rough country, without a lot of good roads, and the prospecting season is short, so no doubt there are many more interesting things to be found.

In a bowl of water use a diamond tip drill and cover the stone with water.

you need to use the drill with very little pressure and drill half way then drill from other side to keep from breaking out the sufface of the hole.

The drill RPM needs to be at least 10,000 - 15,000 RPM.

Here you go... It was mined all over Georgia but mainly in North Carolina

How are gems formed within the earth or how do we fashion gems into the shapes you see in jewelry? If it is how are they fashioned into shapes, we facet them by pressing them on a revolving flat surface that has abrasives on it. You make one facet or window-like spot, then turn it slightly and make another and another. If how they are fashioned within the earth, most theories are pretty close to "You put all the ingredients in a really hot place, put an incredible amount of pressure on it, and wait a real long time."

It is worth anywhere from $50 to $150 depending on condition any your interest level.

Not always the jewelry is stamped, however, no stamp doesnt mean it is not genuine.

gold does not form in a rock. however it does forms along igneous rock and quarts veins. For gold to be present one of these two rocks will more then likely be there as well. (In some large gold nuggets, pieces of quarts will be stuck to the gold)

Depends on the particular purplish crystal. Amethyst is not too expensive but other purplish crystals expensive. So it depends.

"Cheap" is a relative term. 10K gold is cheaper than, say, 14K gold, but more expensive than silver. 10K gold is known for being very durable - it's harder than 14K or 18K gold, so it doesn't ding and dent as easily - and could be better for your needs because of this. But I wouldn't generally say that ANY gold is "cheap", regardless of its purity.

It completely depends on what it is and how old it is. In general, mattel sold most Limited edition Hot Wheels in the $10-$15 range. Most of those cars are readily available on the internet for less. Camaroes and Mustangs seem to hold their value best. Limited cars from the early 1970's may be 1000s of dollars, such as an Ed Shaver AMX. ($5000) Shell limiteds go for a couple of hundred. You would be best served by finding a Tomarts Guide to Hot Wheels or one of the other guides and looking the car up. Expect to get 1/2 the value unless you are looking at rarities.

Garnet.

Hawaii does not have a state mineral, but it's state gem is black coral.

you find it almost everywhere in the world
quarts is located on the earths surface

i lived in Portsmouth (southern) Ohio and there were geodes everywhere. . .we found them in creek beds and hillside cuts. . .they aren't the really flashy colorful type, but there are a lot of them
