Smart Tips to Buy Gold
Everyone knows, gold is the precious metal's most sought-after and popular. Because gold than can be used as a means of investment and hedging your property from the effects of inflation, gold could be used as jewelry. When to buy an investment gold bullion or gold coins.
1. Note the current gold price rate
Of course, before buying gold, you can check how much gold the market today. Some sources you can visit as Goldprice.org, Salamdinar.com and so on. You can get real time information. And a benchmark before went to the gold sellers.
2. Gold purity levels
Here are the levels of purity of gold by international standards:
- 24-karat gold is pure gold (99.99%)
- Gold 22-karat has a gold composition of 91.7% and 8.3% mixed with other ingredients, usually silver
- Gold 20-karat has a gold 83.3% composition
- Gold 18-karat has a gold composition of 75%
- Gold 16-karat has a gold composition of 66.6%
- Gold 14-karat has a gold composition of 58.5%
- Gold 9-karat has a gold composition of 37.5%
Then how about buying a white gold? White gold is pure gold mixed with other metals that have different levels, typically up to 70%. 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.
For example, a mixture of metal alloy composed of 14 parts gold and 10 parts alloy created gold 14-karat, 18 parts of gold compared to 6 parts alloy called gold 18-karat and other.
Thus, it is expressed as the result of the ratio, ie: 14/24 equals 0.585 and 18/24 is 0.750. There are hundreds of possible alloys and mixtures, but in general the Addition of silver will color gold white, and the Addition of copper will color it red. A mix of around 50/50 copper and silver Gives the range of yellow gold alloys the public is accustomed to seeing in the marketplace. A small amount (0.2%) of zinc can be added to Harden the alloy.
See the picture below :
The most common grades of gold, in Addition to pure 24K, 22K acres (92%), 18K (75%), 14K (58%) and 9k (38%).

2. The intermetallic compounds, producing blue and purple golds, as well as other colors. 3. Typically these are brittle but can be used as gems and inlays
