Platinum

Platinum is a white metal, but unlike gold it is used in jewelry in almost its pure form (approximately 95% pure). Platinum is extremely long wearing and is very white, so it does not need to be Rhodium plated like white gold. Platinum is very dense (heavy), so a platinum necklet will feel heavier than an 18kt gold necklet.Platinum is, however, very expensive. A platinum necklet will be approximately twice the price of an 18kt white gold necklet (excluding gemstone costs).
