From ancient times gold was considered as one of the nicest metals because of its yellow-reddish color. High-quality adornments for piercing are made only of 14 and 18 karats gold. Stable structure and fusibility allow to make gold jewelry of the utmost different shapes. 18kt gold is rarely used for relatively big piercing adornments (rods, bananas, etc.), because after the long time of active use the item can lose its initial shape: the greater is hallmark, the softer material is. Allergic reactions to gold occur in people with high sensitivity to metals, which are used in low-quality 9kt adornments. Manufacturing of such adornments is highly common in Asian countries with the use of high-quality gold deposition, which after the short time wears-off, showing its real quality. Such items contain just 37.5% of gold and 62.5% of an additives (copper, nickel, etc.), and wearing of such adornments could cause permanent allergic reaction to gold-containing items.
