The Tsavo Mountains are found in Tanzania and Kenya. This vein was found in 1967 and mining started in 1971. The Tsavorite garnet is an unusual stone. It is a lovely shade of green instead of the red hues most people associate with garnet. Its depth of color rivals that of a fine emerald and so does its price.

Its clarity far exceeds that of most emeralds. It is found only in the Tsavo Mountains of Kenya and Tanzania, and in a small area of Madagascar.

Answer: orange

The Mexican Fire Opal comes in brilliant shades of orange, sometimes with hints of red or yellow. The largest and most productive fire opal mine is found in the state of Queretaro in Central Mexico. This mine is acknowledged as producing some of the finest fire opals on the market. Like all opals, Mexican Fire Opals are a softer gemstone and rate only a 5-6 on the Moh's hardness scale.

Answer: King Tutankhamen's tomb

Lapis is a vivid blue. It is a rock as opposed to a mineral. It was used for all kinds of jewelry in most ancient cultures of Europe, Asia, and Northern Africa.

Chrome diopside is often called Russian diopside. It is a very brilliant green stone, with wonderful translucency. Its only downside is that it is somewhat soft.

Answer: False

Different oysters produce different colored pearls. The black-lipped oyster produces black pearls which have been highly prized throughout history because of their rareness. Also, pink, lavender, peach, and a variety of other shades can be found naturally.

These colored pearls are sometimes more highly prized than white ones, because of their rarity. Pearls that are sold with a bright or very vibrant color are usually dyed. The naturally colored pearls are commonly found in pastel shades, with the exception of black pearls.

Answer: spinel

All of the choices do come in varieties of red, but the correct answer is spinel. Red spinel is usually mined in the same area that rubies are mined. It was not until the 19th century that it was realized that they were two different stones. Spinels often have an unusual inner glow or "fire" to them.

They frequently have better clarity than rubies. However, spinel is slightly softer than a ruby, meaning that a ruby can scratch a spinel but not the other way around.

Answer: Alexandrite Chrysoberyl

The Tiger's Eye changes colors and the banding of colors seems to move if you move the gemstone around in your hand. That is chatoyancy. Turquoise may have slender tangled hairs of black, but the color does not change or move when the position of the stone is changed. Coral and onyx are both solid in color.

Answer: purple & yellow

Ametrine comes from a quartz crystal that is part amethyst and part citrine. It occurs naturally in the Anahi mine in Bolivia. Mining for it has been attempted in other locations. The crystals change color halfway up the shaft. The gemstone is often cut in a square or emerald cut. One half will be purple and the other half will be yellow. No treatment is done to the gem.

It is just another one of Mother Nature's artworks!

Answer: red

While white or colorless diamonds usually demand a high price, they are not the most valuable diamonds. If a diamond is colored, it is called "Fancy". Its price usually skyrockets when compared to a colorless diamond of the same weight, cut, and clarity. Red diamonds are the rarest and the most highly valued.

The largest red diamond in the world is the Moussaieff Red Diamond. It is 5.11 carats and was valued at over seven million dollars by the Gemological Institute of America in 2005.
