Yellow Gold is an alloy made of a mixture of pure gold and either zinc and copper. The higher the karat amount, the more pure the gold.
White Gold is a form of gold with a distinct pale white or cream color; its an alloy of gold and at least one white metal; either nickel, manganese, or palladium, which typically makes up apprx 10% of the alloy.
Rose Gold has a “rose” tint from the gold-copper alloy that composes it. It is also known as “pink gold” and “red gold”, and historically was very popular in Russian, which has also earned it the name “Russian Gold”, though it is far and away most well known as Rose Gold.
Platinum is a metal that is incredibly resistant to corrosion, even at high temperatures. Apart from jewelry, Platinum is used in the treatment of cancer. Because of its white color, it will not cast any tinting on any stones that are used.
Palladium is a beautiful silvery-white metal that resembles Platinum. This metal has become much more valued in recent years and is used in a pure form in jewelry, and for combining with gold to form white-gold alloys. Because of its near white coloring, it will not cast any tinting on any stones it is used with.
Silver is one of the cornerstone precious metals, silver has long been used in jewelry, currency, and investment bullion. It is extremely malleable and pairs beautifully with most stones.
Cobalt is a silver-grey highly magnetic metal, cobalt is used primarily in alloy compounds used in wear-resistant men’s wedding bands. Cobalt can appear blue-hued in the correct light.
Tungsten has the highest boiling point and strongest tensile strength, which means it is nearly impossible to scratch, though under extreme force it will shatter. It is naturally steel grey and has a subdued look.
Titanium is an extremely versatile metal that is resistant to most types of corrosion. It’s value stems from its strength-to-density ratio, the highest amongst any metallic elements.
