Titanium

Titanium as a Ring Metal

Titanium is the hardest natural metal in the world with a distinctive deep-grey tint. It is most often alloyed with aluminum, iron, molybdenum, and manganese. Ounce-for-ounce titanium is one of the strongest readily available metals. Titanium is abundant in nature so it is not considered a precious metal and the metal itself has little value.

The cost of buying a titanium engagement ring is really all in its manufacture. Because of its incredible strength, titanium is difficult to be shaped into delicate scroll work and patters such as Celtic engagement rings without an industrial type process to work the metal and to form it into a ring.


Nevertheless, titanium is a popular metal for jewelry because it can be colored easily to produce other colors including brilliant shades of red, black, blue, green, purple and yellow other than its more familiar greyish tint. In addition, because of its relative inertness, it does not interact easily with other elements and substances, is corrosion free, and resists most acids and other corrosive materials. It is also hypoallergenic, making it suitable for people with hypersensitivities to metals.

Palladium

Palladium as a Ring Metal

Palladium is an extremely rare silvery white metal. It is considered to be a precious metal. It is one of the softer metals in the platinum group. Palladium is becoming a popular alternative to platinum and white gold for engagement rings because its price is between that of gold and platinum. While palladium costs less than platinum, it has many of the visual and strength attributes that make platinum popular. Palladium does not react with oxygen and therefore will not tarnish. Palladium alloys are generally 95% pure, making it hypoallergenic.

Platinum

Platinum as a Ring Metal

Platinum is a precious metal that looks similar to white gold. It is over 30 times rarer than gold but, at current prices, only commands about twice the price of gold. Platinum’s workability is third to that of gold and silver. Platinum is resistant to corrosion. Platinum, like gold, is hypoallergenic.

Platinum used in jewelry is usually a platinum alloy, a mixture of six other related metals: platinum, palladium, iridium, rhodium, ruthenium and osmium. But sometimes it is also mixed with copper and titanium. The platinum used in jewelry is usually 90% and more in purity, meaning that platinum makes up 900 out of 1000 parts of the metal. The purity grade is expressed as 900Plat, Pt900, or 900Pt.

It is highly suggested that you not get a platinum engagement ring with less than 90% platinum because the alloys may change the color of the platinum or reduce its durability.

Gold

Gold, the most Popular Ring Metal

Gold, a precious metal, in its purest form is a shiny yellow metal and is relatively inactive chemically. It resists tarnish and other changes that would dull the shine of other metals. It also means that gold is hypoallergenic, meaning it will not react with your skin and cause an allergic reaction. Gold is the most malleable and ductile of all the metals, meaning that it can be easily worked without breaking.

Because it is extremely soft, pure gold is unsuitable for use as an engagement ring that will be worn everyday. For that reason, other metals, usually silver and copper alloy, are mixed with gold to make gold alloy that is harder and more durable to use for every-day-wear jewelry.


Depending on the amount of the other metals added to the gold, you get 10k, 14k, 18k or 24k gold.

Karat – not to be confused with carat – is a grading system used to indicate the amount of gold in a gold alloy or the quality of a gold alloy:

10 karat (10k) – 10 parts gold and 14 parts other metals or 41.67% purity of gold.
14 karat (14k) – 14 parts gold and 10 parts other metals or 58.33% purity of gold.
18 karat (18k) – 18 parts gold and 6 parts other metals or 75.00% purity of gold.
24 karat (24k) – 24 parts gold and o part other metals or 100% purity of gold.

The higher the gold content, the higher the price, and the softer the gold alloy, the richer gold color. Most engagement rings and wedding rings on the market today are either 14k or 18k gold.

All jewelry is required by law to have a karat grade stamped on it in addition to the trademark of its maker and the country of origin.

Gold is a naturally yellow metal. By mixing yellow gold with some white metals such as silver, palladium, platinum, and zinc alloys creates white gold’s neutral color appearance and shine. This combination makes white gold a tougher metal than yellow gold.

Traditionally nickel was used in white gold. While gold is hypoallergenic, nickel can cause allergic reactions in a sizable portion of the population and is no longer used in most white gold made today.
