Summarize the following:
Deep sky blue stones are the most valuable and, in general, darker shades are more coveted than lighter shades. Choosing an intensity is mostly a matter of personal preference. Heat treatment is a widely accepted practice used to enhance the blueness of a stone. Yellow-brown and yellow-green stones are heated to a temperature between 400C (752F) and 450C (842F) degrees and then cooled. This treatment is permanent and enhances the blueness of the stone without damaging it. Many aquamarine stones are more of a "sea-foam" color than a true blue color before they are heated. Heated aquamarines with a strong blue-green hue cost around $180 per carat. Large aquamarine gemstones are readily available and can be found easily up to 25 carats. Smaller aquamarine gemstones are usually darker in shade, and you will be able to find a higher quality stone at a lower price. Small aquamarines look nice in delicate pieces, but large aquamarines can make a striking statement. Since aquamarine is fairly common, you can usually find large carat stones for affordable prices. For most gemstones, the price per carat rises considerably with more carats, but the price per carat for a 30 carat aquamarine is only percent higher than the price per carat of a 1 carat aquamarine. If you want to place your aquamarine into a piece of jewelry, find a gemstone cut into a typical emerald or oval cut. These cuts are usually a higher quality, since they expose more of the gemstone. If you want to display your aquamarine, you can find pieces that are cut into artistic or abstract shapes.

summary: Pick your desired gemstone shade. Consider a heat-treated aquamarine for a more blue color. Determine the carat weight that you want. Decide what shape you want your aquamarine to be cut in.

The final step is to place the chainsaw on the other side of the tree (the side opposite the wedge you cut). Make a third cut about an inch below the first horizontal cut you made on the opposite side of the tree. Keep cutting into the tree until it topples toward the wedge cut. You may have to use your hands to push the tree top in the direction you want it to fall. NOTE: Do not even attempt this operation if the wind is blowing from the direction in which you want the top to fall. If you have a favorable wind/breeze, you may not have to push on the tree top at all. (It would be much better to top a tree on a day with no wind at all.) Make sure the area where the tree will fall is clear and that people and animals are not nearby. Once the tree top is on the ground, disposal methods will vary by locale. You may have to transport the tree top to your city's dump. In some localities you may be able simply to move the tree top to a nearby wooded area.

summary: Cut into the tree behind your Humboldt cut. Allow the top to fall to the ground. Dispose of the tree top according to local regulations.
