Its color shines in the most beautiful nuances from red to shocking pink. The color of this gemstone is a kind of seductive red. Its components are red, shocking pink and violet vivid. In the fascinating world of the gemstones, it is hardly any other stone which has such a persuasive erotic aura. The color range of the rubellite comprises tender shocking pink as well as ambivalent violet. It takes these two components to get <span style="font-weight: bold"><a href="http://www.tiffanycollections.us/tiffany-1837-toggle-necklace-p-462.html" target="_blank" class="postlink">Tiffany 1837 Toggle Necklace</a></span> the best out of that seductive red. <br /> <br />Tourmalines are closely related gemstones which have been created by Nature in many different colors. In the trade, as a rule, it is not the case that each individual variety has its own name. Instead, the name tourmaline is used and the color simply added, hence red, green, blue or yellow tourmaline. The exception, however, proves the rule. This also applies to the tourmaline and, in particular, to red <span style="font-weight: bold"><a href="http://www.tiffanycollections.us/return-to-tiffany-1837-lock-charm-necklace-p-437.html" target="_blank" class="postlink">Return to Tiffany 1837 lock charm necklace</a></span> and pink specimens. There are red and pink tourmalines in many nuances, which include a tender pink, a fine shocking pink, an intense violet and a bold ruby-red. However, only a few of these are entitled to call themselves 'rubellites'. There is an important criterion for this especially beautiful gemstone, and that is the way its color behaves no difference in daylight and artificial light. Many gemstones change their colors depending on the light source, but a true rubellite does not. It shines just as intensely in artificial light as it does in daylight. The color of most other pink or red tourmalines, by contrast, displays a more or less clearly visible tinge of brown in artificial light. <br /> <br />Whilst colored gemstones in good qualities should as a rule is as free of inclusions as possible, they are looked upon with some favor in the case of the rubellite: indeed it is inclusions that render this stone really interesting from the point of view of the connoisseur. Having said that, they <span style="font-weight: bold"><a href="http://www.tiffanycollections.us/tiffany-star-link-necklace-p-434.html" target="_blank" class="postlink">Tiffany Star Link necklace</a></span> should be subtle, and they must not upset the way in which the light passes through this magnificent gemstone, that could make it look cloudy or milky. Nevertheless, a rubellite with only a few fine inclusions is of course more valuable than one with inclusions which are clearly visible. Rubellites are cut in the most various ways, though the cutter must take account of the varying intensity of the color. Rubellites are mainly found in Brazil, Madagascar, Mozambique, Nigeria and Pakistan. Some beautiful shocking pink rubellites come from a gemstone mine in the USA. <br /> <br />Fortunately, Nature has created the rubellite in many color nuances, so that every woman can select the right rubellite for her type. All she has to do is find it – and that may <span style="font-weight: bold"><a href="http://www.tiffanycollections.us/return-to-tiffany-round-tag-necklace-p-433.html" target="_blank" class="postlink">Return to Tiffany round tag necklace</a></span> not be quite so easy. Today, you can find it from some of wholesale jewelry supplier and wholesale jewelry findings as well. However, the extravagance and beauty of the rubellite will derive a great deal of pleasure to all of you.The platinum with a chemical symbol PT is a sort of precious metal which is classified as a raw material for fine jewelry. Platinum was discovered for centuries ago, it refer to the appearance in 1557 in the writings as a description of an unknown noble metal and became famous in the year of 1920s, it was also known as white gold at that time. As a pure metal, it deserved as a silver white, ductile, and malleable but it does not oxidize at any temperature. It can't be deny that platinum's resistance to wear and tarnish is well suited for making fine jewelry, it is also important for the using of industrial <span style="font-weight: bold"><a href="http://www.tiffanycollections.us/return-to-tiffany-heart-lock-charm-necklace-p-431.html" target="_blank" class="postlink">Return to Tiffany Heart lock charm necklace</a></span> application since it has an excellent resistance to corrosion and high temperature and has stable electrical properties. <br /> <br />Platinum is obtained commercially as a by-product from nickel and copper mining and processing. During electrorefining of copper, noble metals, such as silver, gold and the platinum group metals, as well as selenium and tellurium, settle to the bottom of the cell as "anode mud", which forms the starting point for the extraction of the platinum group metals. <br />The purification methods apply for pure platinum is using to isolate from them by various methods of subtracting impurities. Because platinum is significantly denser than many of its impurities, the lighter impurities can be removed by simply floating them away in a liquid. Besides that , it is also nonmagnetic, while nickel and iron are both magnetic. These two impurities are thus removed by running an electromagnet over the <span style="font-weight: bold"><a href="http://www.tiffanycollections.us/elsa-peretti-open-heart-pearl-necklace-p-429.html" target="_blank" class="postlink">Elsa Peretti Open Heart pearl necklace</a></span> mixture. Because platinum has a higher melting point than most other substances, many impurities can be burned or melted away without melting the platinum. Finally, platinum is resistant to hydrochloric and sulfuric acids, while other substances are not. Metal impurities can be removed by stirring the mixture in either of the two acids and recovering the remaining platinum. <br /> <br />Platinum can widely apply in vary ways but not only in jewelry aspects, it could be used for the vehicle emissions control devices, jewelry, electronics, chemical industry as a catalyst as well as some minor applications, such as electrodes, anticancer drugs, oxygen sensors, spark plugs and turbine engines as well. During periods of sustained economic stability and growth, the price of platinum tends to be as much as twice the price of gold, whereas during periods of economic uncertainty, the price of platinum tends to decrease only because <span style="font-weight: bold"><a href="http://www.tiffanycollections.us/return-to-tiffany-bead-necklace-p-425.html" target="_blank" class="postlink">Return to Tiffany Bead necklace</a></span> <br /> to the decline of industrial demand, falling below the price of gold. Gold prices are more stable in slow economic times, as gold is considered a safe haven and gold demand is not driven by industrial uses.</span></td> </tr> </table></td> </tr> <tr> <td colspan="2" height="1" class="spaceRow"><img src="http://picsrv.fora.pl/Boyz/images/spacer.gif" alt="" width="1" height="1" /></td> </tr> </table>
