If pure platinum is found in placer deposits or other ores it is isolated 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 water bath. Platinum is also non-magnetic, while nickel and iron are both magnetic. These two impurities are thus removed by running an electromagnet over the 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 readily attacked by them. Metal impurities can be removed by stirring the mixture in either of the two acids and recovering the remaining platinum.

Platinum exists in higher abundances on the Moon and in meteorites. Correspondingly, platinum is found in slightly higher abundances at sites of bolide impact on the Earth that are associated with resulting post-impact volcanism, and can be mined economically; the Sudbury is one such example. Platinum together with the rest of the platinum metals 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.

From at least the fourth century BC, India traded in wholesale diamonds, taxed them and exported them. There had long been trade in diamonds between India and Babylon, Mesopotamia, Syria, Israel, Egypt, Ceylon, and Arabian countries. Diamonds that reached the western part of the Roman Empire were prized for their magical powers, but Rome also re-exported the diamonds to China as tool bits set in iron holders for cutting jade and drilling pearls during the first five centuries AD. There were no superstitions about diamonds in China to deny this use and, even as tools, they were still regarded as presents fit for kings, according to the Chinese philosopher Lao-tse in the first century AD.

The Arabs and Persians monopolized trade between the Roman Empire and East Asia and, during the middle ages, between Europe and East Asia until the sea route to India was discovered. It appears that they retained for themselves many of the finest diamonds from India and sold the poorer and smaller ones. The Arab, Teifaschius, issued the earliest diamond price list ever discovered in the twelfth century.

The Greek word “Adamas ” meaning unconquerable and indestructible is the root world of diamond. Diamonds have been sought the world over, fought over, worshipped and used to cast love spells.

For the last 3000 to 4000 years, diamonds have held special magic for Kings, Queens and their sujects. Diamonds have stood for wealth, power, love, spirit and magical powers. Kings in olden days would wear into battle heavy leather breast plates studded with diamonds and other precious stones. It was believed that diamonds were fragments of starts and the teardrops of the Gods. The diamonds possessed magical qualities of the Gods and held powers far beyond the understanding of the common man. Because of these beliefs, the warriors stayed clear of the Kings and others who were fortunate to have the magical diamonds in their breast plates.

Until the 15^th Century only Kings wore diamonds as a symbol of strength, courage and invincibility. Over the centuries, the diamod acquired its unique status as the ultimate gift of love. It was said that Cupid’s arrows were topped with diamonds that have a magic that nothing else can equal.
