What is 24K Gold?
Because of the softness of pure (24K) Gold, it is usually alloyed with base metals for use in jewelry, altering its hardness and ductiflity, melting point, color and other properties. Alloys with lower "k", typically, 22k, 18k, 14k or 10k, contain higher percentages of copper, silver or other base metals in the alloy.
Medium of monetary exchange.
In various countries, gold is used as a standard for monetary exchange, in coinage and in jewelry. Pure gold is too soft for ordinary use and is typically hardened by alloying with copper or other base metals. The gold content of gold alloys is measured in carats (k), pure gold being designated as 24k.
Gold coins intended for circulation from 1526 into the 1930s were typically a standard 22k alloy called crown gold, for hardness. Modern collector/investment bullion coins (which do not require good mechanical wear properties) are typically 24k, although the American Gold Eagle and British gold sovereign continue to be made at 22k, on historical tradition. The Canadian Gold Maple Leaf coin contains the highest purity gold of any popular bullion coin, at 99.999% (.99999 fine). Several other 99.99% pure gold coins are currently available, including Australia's Gold Kangaroos (first appearing in 1986 as the Australian Gold Nugget, with the kangaroo theme appearing in 1989), the several coins of the Australian Lunar Calendar series, and the Austrian Philharmonic. In 2006, the U.S. Mint began production of the American Buffalo gold bullion coin also at 99.99% purity.
Today, gold has fallen out of use in coins made for general circulation.

What is Rhodium?
From Wikipedia, the free encyclopedia
Rhodium (pronounced /ˈroʊdiəm/) is a chemical element in the periodic table that has the symbol Rh and atomic number 45. A rare silvery-white hard transition metal and a member of the platinum group, rhodium is found in platinum ores and is used in alloys with platinum and as a catalyst. It is the most expensive precious metal.
What is Silver?
.925 Sterling Silver is an alloy of silver containing 92.5% pure silver and 7.5% other metals, usually copper.
Fine silver (99.9% pure) is generally too soft for producing large functional objects, and in Sterling Silver, the silver is usually alloyed with copper to give strength whilst preserving the malleability of the silver and a high precious metal content - ideal for making silver jewelry.
Other metals can replace the copper, usually with the intent to improve various properties of the basic sterling alloy such as reducing casting porosity, eliminating firescale (a red or purple stain), and increasing resistance to tarnish. These replacement metals include germanium, zinc, and platinum, as well as a variety of other additives including silicon and boron. A number of alloys claiming firescale and/or tarnish resistance have appeared in recent years sparking heavy competition between the various manufacturers and their different formulations. No one alloy has emerged as an industry leader or standard and ongoing alloy development is a very active area.
