Platinum is one of the rarest and most durable precious metals. Platinum's rich, white luster enhances the brilliance and will maintain its shining luminosity forever, unlike other white metals which, in time, turn yellow or tarnish.
Platinum belongs to the noble and precious metals family. It is resistant to tarnishing and discoloration due to chlorine and other chemicals. These factors, along with its strength and white luster, have made platinum an increasingly popular choice for jewelry, either on its own or as the setting for diamonds and other precious gemstones. Platinum jewelry does not fade or tarnish and keeps its looks for a lifetime. Platinum's purity makes it hypoallergenic and ideal for those with sensitive skin.
Platinum is rare, the coveted treasure of discerning individuals. Platinum is one of the strongest and most enduring metals. Some of the world's greatest treasures are set in platinum, such as the Hope Diamond. It is also one of the heaviest, weighing 60% more than gold. The word platinum sometimes enjoys a cachet higher even than gold - witness all those platinum albums and credit cards.
Platinum jewelry is the perfect choice for a lifetime of everyday wear. Its density and weight make it a durable jewelry metal. Platinum does not wear away and holds precious stones firmly and securely. Like all precious metals, platinum scratches. However, the scratch on a platinum piece is merely a displacement of the metal and none of its volume is lost. In addition to its strength and density, platinum has another remarkable quality - pliability.
Platinum is a symbol of true love, purity, rarity and strength. These qualities of platinum are equivalent to the ideals of eternal true love. All over the world, engagement rings, wedding bands and anniversary rings made in platinum symbolize the everlasting endurance of love.
