Each of these white metals has unique attributes that have both benefits and disadvantages. Here is a brief overview of the more common characteristics.
Sterling Silver is a very affordable, pure white metal however it is very soft and therefore not suitable for high intensity wear or for securing expensive precious gemstones. Sterling Silver can be modified, melted, reshaped and soldered.
Platinum is another pure white metal. It is tremendously dense (approx 60% more so than white gold) and has an extremely high melting point. These two characteristics translate to a metal that is very difficult to solder, reshape and polish, thus driving the cost of platinum jewelry and platinum jewelry repair much higher than its more common counterpart- white gold. The high density however, makes the metal ideal for securing precious gemstones and will wear down much more slowly over time than gold. Platinum can be modified, melted, reshaped and soldered.
White Gold is a not a true white metal. Because pure gold is a yellow metal, this color presents itself as subtle undertone giving white gold a “warm white” tone. Most white gold jewelry is plated with Rhodium (a pure white metal from the platinum family) to give a purer white look. This plating will wear away over time or with high intensity use. White gold can be modified, melted, reshaped and soldered.
Titanium is an extremely hard, gunmetal grey metal. It is extremely light and affordable but has some downsides as well. Titanium can be cut (for example rings can be cut off if needed) but it cannot be reworked or sized like platinum, gold or silver using traditional jewelers tools. It is also more prone to everyday scuffs and scratches. Titanium’s darker tones, hardness and affordability make it a favorite for young men’s wedding bands.
Tungsten is another extremely hard, gunmetal grey metal but unlike titanium it is very dense and heavy. Tungsten’s nearly scratch proof quality coupled with its affordability make it another favorite for young men’s wedding bands.
