Vancouver Diamonds offers two metal types to choose from: Gold and Platinum.
The most common grades of gold, in addition to pure 24K, are 22K (92%), 18K (75%), 14K (58%), 10k (41%) and 9K (38%)
While pure gold is yellow in color, gold can be developed into various colors. These colors are generally obtained by alloying gold with other elements in various proportions.For example, alloys which are mixed 14 parts gold to 10 parts alloy create 14-karat gold, 18 parts gold to 6 parts alloy creates 18 karat, and so on.
White gold - is an alloy of gold and at least one white metal, usually nickel, manganese or palladium. Like yellow gold, the purity of white gold is given in karats. A common white gold formulation consists of 90 wt.% gold and 10 wt.% nickel.
White gold's properties vary depending on the metals and proportions used. As a result, white gold alloys can be used for many different purposes; while a nickel alloy is hard and strong and therefore good for rings and pins, gold-palladium alloys are soft, pliable and good for white gold gemstone settings.
Rose gold - is a gold and copper alloy widely used for specialized jewelry. It is also known as pink gold and red gold. As it was popular in Russia at the beginning of the nineteenth century, it is also known as Russian gold, but this term is now obsolete.Although the names are often used interchangeably, the difference between red, rose, and pink gold is the copper content – the higher the copper content, the stronger the red coloration. A common alloy for rose gold is 75% gold and 25% copper by mass (18 karat). Since rose gold is an alloy, there is no such thing as "pure rose gold".
A pure metal, platinum is silver-white in color, lustrous, ductile, and malleable. Platinum is more ductile than gold, silver and copper, thus being the most ductile of pure metals, but gold is still more malleable than platinum. It does not oxidize at any temperature, although it is corroded by halogens, cyanides, sulfur, and caustic alkalis. Platinum is insoluble in hydrochloric and nitric acid, but dissolves in hot aqua regia to form chloroplatinic acid.
Platinum's resistance to wear and tarnish is well suited for making fine jewelry. Pure platinum is slightly harder than pure iron. The metal has an excellent resistance to corrosion and high temperature and has stable electrical properties. All of these characteristics have been used for industrial applications
