65 percent of the world's diamonds come from Africa which is where the issue of blood diamonds is the biggest concern. In the past these diamonds could end up anywhere and no one would know any better. Recently there have been checks and balances put in place to stop the majority of blood diamonds from leaving Africa. Africa, Liberia, Angola, and Sierra Leone are places that blood diamonds are traded for arms or used to fund wars and terrorism.

What is the rarest item on earth?
Astatine is a highly radioactive material. It has a silvery color to it. It was discovered in 1940 and you can most likely find it in natural minerals. This element is so rare that the entire amount of its natural occurrence on the earth's crust would equal to 1 teaspoon. Cool right!?!?!? AND THE SECOND IS BUTTNUGGETS! Buttnuggets are RARELY found in a very fat person's asshowel! LAWLZ

Where can you geodes in Pittsburgh?
Crystal River Gemsspecializes in geodes, crystals, agates, and other natural gifts. The store is located in Fifth Avenue Place, at the corner of Fifth and Liberty avenues in the heart of Downtown Pittsburgh.
Another place of interest to geode enthusiasts is the Carnegie Museum of Natural History. The museum's Hillman Hall of Minerals and Gems contains over 1300 specimens of minerals, gems, ores, and metals. The current exhibit hall, which opened in 1980, was expanded and remodeled from 2006-2007.
Pittsburgh-area geode enthusiasts may also be interested in the Monongahela Rockhounds, a mineral, fossil, and lapidary club. Field trips to collect specimens at quarries or other collecting sites are arranged two to three times a year, and there is an annual gem, mineral, and fossil show in April. Members receive the monthly newsletter Monongahela Rockhound News, and meetings are held in the Munhall Borough Building in Homestead, just outside Pittsburgh.
What color of topaz can you get?
Topaz is a gemstone of all colors (Orange, yellow, brown, light blue to deep sky-blue, pink, colorless, white, light purple, greenish-blue, green), and its most valuable color is a golden orange-yellow, called "imperial topaz". Topaz is commonly thought of as a sky-blue gem, but it was not until this century that blue topaz became widespread on the gem market. Natural blue topaz with a deep hue is very uncommon in nature; colorless to light hued stones are heat-treated to achieve the blue color. Likewise, topaz rarely occurs naturally in pink; virtually all pink topaz is heat treated from yellow or brownish material. Some topaz from Russian localities are notorious for fading upon prolonged exposure to light. Stones from these localities are undesirable as gems. One should always inquire about the origin of the topaz before buying it to make sure it will not fade. Topaz of all different colors are used in jewelry. The orange, pink, and blue colors are most often cut for gems, and colorless topaz is sometimes cut with the brilliant cut, resembling diamond. Topaz is sometimes found as enormous flawless crystals, and some gigantic gems and faceted spheres have been formed from them, making unique and exquisite gem pieces. Topaz is rarely cut into cabochons.
VARIETIES
On the gem market, topaz is usually classified by color. Below is a list of the color names designated for gem topaz:
Pink Topaz
Blue Topaz
Brown Topaz

Imperial Topaz - lustrous orange-yellow to orange-brown variety of topaz (most valued)
Silver Topaz - colorless topaz
Sherry Topaz - orange-brown topaz
London Blue Topaz - deep blue topaz (the deepest blue form of topaz)

Paraiba Topaz - sea-green topaz
False names:
Smoky Topaz is also a false name for Topaz. It is used by unscrupulous dealers to describe Smoky Quartz.
Hyacinth is an orange-yellow to yellow-brown variety of Topaz. Although the name Hyacinth usually is used to describe a gem variety of Zircon of that color, it is occasionally used for Topaz as well (usually in old manuscripts). Pycnite is a columnar variety of Topaz. It may also refer to a yellow-white variety Gold Topaz
Golden Topaz
Madeira Topaz
False Topaz
Brazilian Topaz
Bahia Topaz
Citrine Topaz
Brazilian Topaz - yellow to yellow-brown sapphire
Indian Topaz - yellow to yellow-brown sapphire
King Topaz - yellow to yellow-brown sapphire
Oriental Topaz - yellow to yellow-brown sapphire
Smoky Topaz - unscrupulous name for cut smoky quartz
Star Topaz - yellow star sapphire
There is also Mystic topaz, which is not a natural topaz is it made by adding some chemicals on the base on the colorless topaz to make it look colorful and is often cut in concave style to enhance the luster. Note: Citrine (a yellow-brown variety of Quartz) closely resembles yellow-brown Topaz. Unfortunately, unscrupulous dealers have adapted false name for Citrine so the unaware buyer thinks he is buying the more valuable Topaz. Any "Topaz" labeled with a prefix name (such as Gold Topaz, Madeira Topaz, False Topaz, Brazilian Topaz, Bahia Topaz, and Citrine Topaz) is heat-treated Citrine. However, there are three exceptions:
it depends on its color and size. Keep in mind that topaz is more expensive than Quartz

Explain why cut diamonds have billiance and why they have fire?
Cut diamonds have brilliance because of their ability to reflect and refract light, creating intense sparkle and brightness. They have fire due to their dispersion properties, which splits white light into its spectral colors, producing flashes of colored light. These two optical properties contribute to the overall beauty and attractiveness of a diamond.

Why is point nine repeating equal to one?
To answer that question we should first talk about why any non-termination decimal number is equal to whatever it is. And to talk about that, we should first talk about the value of ordinary terminating decimals. Consider a terminating decimal, say 0.314. This decimal represents the sum of the fractions 3/10 + 1/100 + 4/1000; and longer (but still terminating) decimals can be computed in a similar way. But how do we decide what value a non-terminating decimal represents, say 0.314159265458979... and so on with a never-ending sequence of digits? By analogy, it should be equal to 3/10 + 1/100 + 4/1000 + 1/10,000 + ... and so on; but how can we figure out what such a never-ending sum adds up to? Well, one way of looking at it is as follows: Whatever value the decimal has, we know that (say)0.314 is off by no more than 0.001, since 0.314159... - 0.314 = 0.000159..., and 0.000159... is clearly < 0.001. Likewise, 0.3141 is off by no more than 0.0001, and 0.31415 is off by no more than 0.00001, and so on. In other words, the sequence of (terminating) decimals, 0.3, 0.31, 0.314, 0.3141, 0.31415, etc. gives us a list of better and better approximations to the ultimate value of the non-terminating decimal; and in fact by taking enough decimal places, the error in the approximation can be made as small as you like. If you've studied calculus, you may recognize this sort of discussion--it means that the value of the non-terminating decimal acts like the limit of the sequence of terminating decimals. In fact, it just *is* the limit of the sequence. So mathematicians have chosen to define the value of a non-terminating decimal as the limit of the sequence of approximations. Now we can talk about the specific case of 0.9 repeating: It turns out that the limit of the sequence 0.9, 0.99, 0.999, ... is just equal to 1, exactly (which should not be too hard to convince yourself of) and therefore the value of the non-terminating decimal 0.9 repeating is, by definition, equal to 1.
What packaging material would best protect a fragile object?
It depends.
a Fragile object of odd shape with protruding parts will be best protected in a cardboard box filled with Styrofoam peanuts.
a Vase or Pottery would be well protected wrapped with bubble wrap and boxed.
plates and chinaware can be protected with blank newsprint paper and of course boxed
there is also plenty of specialized packaging materials
