Ruined bracelet
A few days ago I received a picture from a friend and asked for help to see if her mother’s bracelet was ivory. I have a look, well, ivory is ivory, but unfortunately the wear and tear is not the same, it makes people feel bad. It turned out that a friend said that the bracelet is her mother's wedding gift, and she has been doing housework for a long time. She has never taken it for more than 20 years. It is not surprising that a beautiful bracelet is worn out like this.
Trouble with jewelry maintenance
I believe that friends who like jewelry will have such troubles. At the beginning, they don’t know how to care for their baby. They are always careful and worried about the damage to the jewelry, but they still inadvertently leave damage to their beloved jewelry. Later, everyone must have read a lot of articles, and learned about the wearing methods and maintenance methods of many gems, but there are so many rules and regulations, and where do you remember? And maintaining jewelry is also a matter of distraction, if there is a way to do it once and for all.
So, is there a way to do it once and for all? The answer is yes. Today, we will introduce you to several kinds of jewellery that basically does not require maintenance and can not be destroyed. It will relieve the burden of maintenance for everyone.
First, red sapphire
If it is beautiful and durable, it is easy to think of diamonds, which have the highest hardness. However, what people often don't know is that the toughness of diamonds is very poor, because the problem of internal cleavage is often cracked by the impact of external forces. As a red sapphire of corundum, it not only has a variety of beautiful colors, but also has a hardness of up to Mohs 9, which is second only to diamonds in natural gemstones, and its toughness is also very good. When worn, whether it is bump or rub, It won't have much impact on red sapphires, so there is no doubt that Red and Blue is ranked first.
Second, diamond
With its Mohs hardness of 10 as the hardest gemstone, the diamond is undoubtedly ranked second. What I have just said is that the toughness of diamonds is poor. Although you don't have to worry about being scratched during the wearing process, you should pay attention to prevent bumps.
Third, gold emerald
Compared with red sapphires and diamonds, gold emeralds are a relatively new gemstone variety, but they also have a short history. Beautiful color, extremely high clarity, and Mohs 8.5 hardness and relatively good toughness make it a place in the field of high-end gemstones. Among them, the Alexander stone type with the color change effect and the opal with the cat eye effect are more valuable. Just wear it when you wear it, don't rub it with diamonds or red sapphire.
Fourth, spinel
Spinel has the fascinating color of ruby, and the hardness of up to Mohs 8, which has gradually increased in value in recent years. Usually, you only need to pay attention to not rubbing with the jewel with higher hardness.
Fifth, Topaz
The topaz mineral name is Topaz, a gemstone with a hardness of 8 Mohs. Common colorless and light blue. Rarely yellow, red, and dark blue are mostly the result of manual processing. There are very few gemstones in nature that are harder than topaz, so they are generally not easily scratched during wear. It should be noted that the topaz has a set of cleavage, which needs to be prevented from being bumped when worn to avoid cracking along the cleavage.
Sixth, tourmaline and aquamarine
The Mohs hardness of tourmaline and sea sapphire is between 7-8. Usually, wear it without rubbing against high-hardness gemstones. If there are cracks, it is necessary to prevent bumps.
Seventh, crystal
Crystal's Mohs hardness is 7, a common high-hardness gem in nature. The dust in the air has a hardness of up to 7, which is fine quartz particles. Therefore, a stone with a hardness of less than 7 is easily worn in the air, and the crystal remains bright. Care should be taken not to rub against higher hardness stones when wearing.
Eighth, jade
The Mohs hardness of jadeite is between 6.5 and 7, not particularly high, but it is not very low. It is worth noting that due to its fiber interweaving structure, the jadeite with excellent texture is excellent, and it is not easy to be bumped during wearing. Cause damage, just pay attention to prevent being scratched by high hardness stones.
Remote Electric Roller Curtain
For a family, no one likes their every move in view of others. In this regard, different indoor areas have different standards of privacy concern. Area of public activity of member of this kind of family sitting room, to the requirement of privacy is inferior, major domestic sitting room is to pull open the curtain, be in adornment state below major circumstance.
