    wholesale jewelry australia By distinguishing pure gold, you can rely on the following methods:
    It look at the color, the color of the gold is dark yellow. If it is not pure, then light yellow, the larger the purity, the darker the color. Red yellow color is above 95 %, light red yellow yellow 90-95 %, pale yellow is 80--85 %, cyan yellow 65-70 %, color blue with white light is only 50-60 %, slightly yellow and white and white Less than 50 %.
    Themark. Gold is the finished product made by the state in accordance with the production standards. At the same time, there are also tags. This mark will mark the number of gold on the gold, such as 18K, 24K, and so on, but the low color is not given this mark, so the basic color that can be played is high. Sometimes you need to amplify the mirror to check the mark to distinguish the authenticity.
    sound. Gold also has the sound of its own metal. Generally, the higher the purity, the sound of throwing on the ground, the sound can be popped, if it is not pure, then the dullness will be made
    The real gold is not afraid of fire. That's right, take gold with fire until it becomes red, and then observe what color of the appearance of the gold after cooling. If it is still the original golden yellow, it means that the purity of the gold is relatively pure. Then it shows that there are flaws, which may be fake gold jewelry.
