Foot gold purity secrets: How to distinguish the full gold jewelry that is difficult to distinguish between true and false?

Foot gold jewelry is highly sought after in the market, but because of its high value, it has become the target of some illegal merchants.How to distinguish between true and false has become the focus of consumers' attention.This article will start with the purity of the foot gold to reveal how the full gold jewelry that is difficult to distinguish between the true and false distinguishers.

What is foot gold?

First of all, we need to know what "foot gold" is.The so -called "foot gold" refers to alloy containing more than 99.9%of the gold ingredients, which is usually represented by "999".This means that 999 in the alloy is gold, and the rest may be expensive or cheap valuable or non -precious materials.

Visual inspection

Appearance inspection is the most intuitive and easiest way to judge authenticity.First of all, pay attention to whether there is a logo "999" or similar logo on the jewelry; secondly, pay attention to the color and luster. The high -quality foot gold should have bright and uniform color and luster; in addition, pay attention to whether there are oxidation and discoloration.

chemical test

In addition to the appearance inspection, you can also verify whether the jewelry can be used by chemical testing whether it is a real sufficient gold.You can use professional devices to perform X -ray fluorescent analysis (XRF) on the sample. This method can accurately determine the content of various element in the material and determine whether it meets the standard.

Density

Another method to distinguish authenticity is density determination.Because different materials have different density, the density density is higher at the same volume.The actual density of the object can be concluded by simply weighing and calculating the volume, and compares with the yellow iron ore (that is, the pupae).

Summarize:

In summary:

1. The appearance inspection includes identification, color, gloss, etc.

2. Chemical test can be verified by equipment such as XRF;

2. Density measurement is different from physical characteristics.

Consumers should leave more attentive aspects when buying, and try to choose regular channels to avoid purchasing inferior products.
