The topaz has superb qualities of color, clarity and hardness. Its. hardness
allows it to be easily polished because it contains an innate smoothness. The
smoothness and slipperiness of topaz is one of the ways it is identified along
with the brilliancy of color. It comes in all different shades of yellow, blue,
brown and rose reds. Most deep blue hues are produced artificially by heat and
irridation. Citrine is sometimes mistaken for topaz. The more intense colors of
topaz is what usually sets it apart from the lighter citrine colors. However,
there is a test known as the "methylene iodide test" that can make a final
determination. A stone is place in the solution, and a citrine gem will float
while the topaz will sink to the bottom. While hardness is a definite prime
attribute, topaz has a real disadvantage with its. basal cleavage. This makes
the stone very sensitive to sharp blows so artisans and miners have to handle it
very carefully.

Two Afrikaner brothers owned a farm where the Orange and Vaal rivers join.
Johannes Nicholas de Beer and Diederik Arnoldus de Beer had diamonds discovered
on their property. They were in no position to protect the property from diamond
hunters and predators so they sold it for 6300 pounds to investors Cecil Rhodes
and Charles Rudd. Two mines were actually found on the property located in the
Kimberly region. One mine was named after the original owners of the property,
and the other one was named after the area. The De Beers and Kimberly mines were
consequently born. Rhodes and Rudd merged the two enterprises to form De Beers
Consolidated Mines Limited. It couldn't have happened at a better time.

emstones are also found in jewelry in the form of beads. Beads come in all
shapes and sizes and have a hole in the middle that allows them to be strung.
Gemstone beads are similar to cabochons in that they use stones that are not
clear enough to be faceted, and generally are less valuable. There are always
exceptions however: one of them is pearls. Pearls are as valuable as beads as
they are simply set.
