Six tricks to teach you how to buy diamonds
Diamond is the hardest substance in nature, with a bright appearance and a hard and eternal essence, which is why people like it. With the popularity of diamonds, more and more people like them. Diamond ring is the most precious love gift between lovers, so how to buy diamonds has become the focus of many people's attention. Then let's talk about how to buy diamonds.
How to buy diamonds
1, hardness test
Diamond is the hardest natural substance known, and nothing can mark it. If you can mark it, it's definitely not a diamond.
2. Thermal conductivity test
At the same time, breathe into the diamonds and other similar objects to be debated. If it is a diamond, the water mist condensed on its surface should evaporate faster than other objects, because the thermal conductivity of the diamond is high.
Step 3 Observe the reflected light
With a magnifying glass, it can be observed that the waist of the diamond presents a very fine matte shape, and the reflected light shines. This characteristic of diamonds is unique.
Step 4 look at the growing point
Observing under a magnifying glass, there are often grooves and triangular growth points on the crystal face of real diamonds, while there are two kinds of fakes:
(1) Ordinary glass containing alumina is easy to be misplaced due to the increase of refractive index and dispersion, but its hardness is low.
(2) Imitated with chemically synthesized sapphire and colorless spinel, the hardness is similar, but the refractive index is low and has birefringence, and the double image can be seen under a magnifying glass.
5, similar chemical composition test
Pencils have the same chemical composition as diamonds, but different physical structures. So many people use pencils to test the authenticity of a diamond, which is a practical and effective method. When identifying, first wet the diamond with water, and then lightly stroke the crystal face of the real diamond with a pencil, leaving no trace where the pencil strokes.
But if it is not diamond, but glass, crystal and other materials, it will leave traces on the surface. In general, it is more accurate to identify the authenticity of diamonds with pencils.
6, artificial zirconia imitation
High hardness and good refraction, but it will reflect more colored light when rotating, which is obviously different from the genuine product that only reflects weak yellow and blue colored light when rotating.
How to choose diamonds? Diamonds shine in your fingers for a lifetime of happiness. Diamond ring has become an important "guest" to propose or get married. Diamonds are as pure, eternal, precious and rare as people hope for love, which is exactly what people are pursuing.
Matters needing attention in purchasing diamond jewelry
What are the precautions for the elderly to buy diamond jewelry? Maybe you still think that diamond jewelry is a patent for young people. In fact, more and more old people like to wear diamond jewelry now, and bright diamond jewelry will set off the light of the old people. However, it is also skillful to choose a suitable diamond jewelry for the elderly. Today, Bian Xiao shares with you the precautions for the elderly to buy diamond jewelry.
First of all, the choice of diamond jewelry style is best in line with the stable and mature style of the elderly. Jewelry that the elderly like to wear is usually simple and quaint.
Therefore, when choosing diamond jewelry for parents and elders at home, it is best to give up any fashionable and unconventional jewelry styles, but choose a diamond jewelry with classic shape and simple design. These classic diamond jewelry styles are very popular with the elderly.
Secondly, the inlay method of diamond jewelry is something we should pay attention to when purchasing, and it is also related to the problem of wearing by the elderly. For example, the diamond is inlaid in a higher position by means of pointed inlay and embedded inlay, and it is easy to damage the diamond because of careless bumping when wearing it.
If young people wear it, they can pay more attention, but if old people wear it, they may not notice it. Moreover, if the diamond ornaments are too dazzling, they are not suitable for the elderly to wear. On the contrary, the mosaic style such as mosaic can not only hide the light of some diamonds, but also protect them well.
Finally, it is best not to buy sharp diamond jewelry for the elderly. Some diamond jewelry designs are very beautiful, but the edge of the jewelry has a sharp part, so this kind of jewelry is not suitable for the elderly to wear, and it is easy to scratch the skin of the elderly. Therefore, to buy diamond jewelry for the elders at home, it is best to choose those styles with rounded corners and smooth feel.
If your parents also like to wear bright diamond jewelry, buy them one quickly. But in the process of purchasing diamond jewelry, we should pay attention to these shopping items and choose a diamond jewelry suitable for the elderly!
