Gold
Gold is the most popular jewelry metal for men’s and women’s wedding and engagement rings, and is also customarily used in the crafting of earrings, pendants, brooches, necklaces and bracelets. Gold is a highly valuable metal, and is one of the most coveted metals in all of history. Gold symbolizes riches, wealth, and good standing, and in its purest form, is impossible to tarnish. Gold jewelry is sophisticated and refined, and is a divine and precious metal that is perfect for all occasions.
Pure (24-karat) gold can sometimes be too soft and malleable for everyday wear. Therefore, gold jewelry is usually complemented by a mixture of other alloyed metals (such as silver, copper, nickel and zinc) to help it retain more resistance and strength. While purer gold’s are rarer and more exotic, they are oftentimes prone to being bent or twisted. Since other alloying metals are employed to build gold jewelry’s resistance, gold then becomes more likely to stain or to tarnish. Pure gold can never tarnish, but in gold pieces that are mixed with components of nickel, slight discoloration may occur over time, and it is possible for the gold compound to leave a dark residue on the skin. When purchasing gold jewelry, it is best to stick to the higher karat gold. If the gold jewelry is to be worn everyday, make sure it is between 14-18 karat gold. (The karat measurement denotes what percentage of the gold jewelry is made of pure gold. For example, 18k gold is 18/24 real gold, or 75% pure gold.)
Silver
Silver is perhaps one of the most popular jewelry metals because it is much more abundant in nature and therefore more affordable than its competitor metals. Sterling silver, which is 92.5% pure silver, is the best quality of silver metal for setting precious stones and adorning fancy jewelry.
Silver can tarnish rather easily and is less durable than other jewelry metals such as gold and platinum. Silver in its purest form is even softer than pure gold, so finer quality silvers are not always appropriate for everyday wear. Silver can also be prone to oxidation, sometimes causing slight discoloration and blackening of the metal. Luckily, it is easy to make silver jewelry look brand new again by simply purchasing a silver jewelry cleaning solution at little cost (which can be found in most department stores).
White Gold
White Gold a greater percentage of nickel in a gold metal alloy mixture gives white gold its color, while a higher percentage of copper will turn gold a more reddish hue, resulting in ‘rose gold.’ White gold is simply gold that has been chemically treated and then coated with another white medal called Rhodium. Rhodium metal has similar properties to platinum and gives white gold its pristine color and shine.
While white gold is a very hard metal thanks in part to its Rhodium coating, it does wear eventually. To keep a white gold ring from fading and loosing its luster, you should get your white gold jewelry re-Rhodium-plated approximately once a year or at least every 18 months. Most local jewelers can re-coat white gold jewelry at a cost effective price.
Platinum
Platinum is a clean, sharp- looking jewelry metal, and is second to none in terms of durability. Platinum is so strong that it is impossible to tarnish and it has the highest melting point of the popular jewelry metals. Platinum jewelry is generally composed of 90% platinum and 10% iridium. The innate strength of this metal makes platinum the ideal choice for setting precious stones.
While platinum is the best in terms of toughness and can outlive its rival jewelry metals in terms of appearance and strength, it is important to consider its price. Platinum is rarer, more durable, and therefore, more expensive, than gold. With all other things being equal, a platinum ring will cost approximately twice the price of a white gold ring of 18 karats. It is, however, a prime material for the careful crafting of wedding rings.
Palladium
Palladium is harder, lighter, and less expensive than platinum. It is a close substitute in look and feel, and palladium jewelry can endure the perils of everyday wear and tear and come out spotless.
While Palladium aims to imitate platinum, it cannot truly fool anyone. Palladium metal lacks the prestigious ‘platinum’ insignia; marked on the inside rim of every platinum jewelry piece will be a small stamped engraving bearing the word: ‘plat.’ So if you are looking to trick someone into thinking you have purchased ‘the real thing’, it might be more difficult to do so than you had previously imagined.
Titanium
Titanium is the hardest naturally-occurring metal in the world. This makes titanium the perfect metal for fine jewelry, especially rings. Titanium is three times as strong as steel, yet maintains a light and comfortable weight. Titanium jewelry will not bend, scratch or dent. Most importantly, pure titanium jewelry is 100% hypoallergenic, meaning that it will not cause allergic reactions and is safe for anyone to wear.
The one and only foreseeable downside to purchasing titanium jewelry is that it cannot be soldered, rendering it impossible to re-size a ring made of the substance.
