It pure
The platinum luster and white, natural and pure, is a perfect expression and a true reflection. The purity of platinum jewelry is generally 95 % (while the purity of 18K gold is only 75 %), so it will not fade or change color, and it can still be shiny in the passage of time. Platinum's purity contains excellent white luster, which can best reflect the real light of diamonds. Platinum is also very suitable for skin loading. Because it does not contain impurities like other metals, platinum does not cause allergic reactions to the skin.
The eternal
The density and weight of platinum make it more durable than other jewelry metal. The weight of a six -inch square (15 cm) platinum cube weighs 165 pounds (75 kg), which is equivalent to the weight of an ordinary man. Platinum heat -resistant and acid -resistant, high melting point, is 3223 degrees (1768 degrees Celsius). Platinum does not wear it, and can fix the precious jewelry stably and safely. Some world -renowned gems are fixed in the platinum base, such as Ke -El -Nole diamonds and some jewelry on the British crown. All valuable metals will leave scratches, and platinum is no exception. However, the scratches on platinum only move the metal and will not reduce its volume, and the gold scratches will bring wear and reduce the volume of gold. If there are indeed scratches on the naked eye on the platinum, qualified jewelry vendors can be polished for it.
Maked use
In addition to strength and density, platinum also has another excellent quality: flexibility. Platinum is very flexible. With only 1 gram of platinum, it can be pulled into a filament of more than 1 mile (nearly 2 kilometers). This quality, plus the strength of platinum, allows jewelry dealers to create extremely flexible mesh platinum jewelry, while other valuable metals must never do this. Platinum is also necessary in other fields: it can be used in the industrial field, and the most famous is to catalyze the reactor. Platinum also plays an important role in the medical field. It is not affected by blood oxidation. It is excellent conductive and can be compatible with biopsy. Due to the above characteristics, platinum is applied to a heart -rising device. At present, more than 50,000 people live in a healthy manner on the heart. For them, platinum is a metal that can save life.
