Gold is a very stable precious metal. Since ancient times, gold has been a symbol of wealth and one of the very rare and precious metals. Because gold jewelry used to be worn by rich people, now the living standard has improved and many people can afford it. There are hard gold and thousands of gold on the market at present. Although hard gold and thousands of pure gold are both gold, the material technology and price are different, so the quality is different. Let me distinguish the difference between them.
Pure gold is gold with a purity of ≥99%. (In other words, gold or gold ornaments with a gold content of not less than 99% are called pure gold. Thousands of pure gold means that the purity of gold is ≥99.9%. (That is to say, gold or gold ornaments with a gold content of not less than 99.9% are called pure gold, which is the previous statement. ) From May 4th, 20 16, the gold ornaments sold will no longer have the title of "thousands of gold", and all will be unified as "pure gold", that is to say, there can be no names of thousands of gold and thousands of gold. Now there are jewelry stores that advertise the purity of their gold and then sell it at a high price. In fact, 99 gold jewelry is the same as 999 gold jewelry now, and it makes no difference to wear it again, and the recycling price is the same.
The difference between pure gold and hard gold:
1, in terms of purity, hard gold and pure gold are both gold, and the gold content is the same, so some friends say that hard gold is an alloy, which is wrong. Mark hard gold with the words hard gold or 3D hard gold exceeding thousands of gold.
2. In terms of hardness, the difference between 3d hard gold and thousands of gold jewelry: the hardness is four times that of thousands of gold, so hard gold has high wear resistance. Compared with thousands of gold, hard gold jewelry is exquisite in workmanship and comfortable to wear.
3. From the cumulative weight, the difference between hard gold and thousands of gold jewelry: hard gold adopts hollow nano electroforming technology. So that the weight of hard gold jewelry of the same size is only 30% of that of thousands of gold. Just like the bracelet with thousands of gold below, it needs 20.29 grams, which is more than 7,000 yuan according to the gold price in 340 yuan. If it is hard gold, it is 4g at most, which is about 1000 to 2000. Many people can afford gold jewelry.
4. In terms of style and modeling, the difference between 3d hard gold and thousands of gold jewelry lies in that the hard gold is inverted by wax mold, so that gold can be fully displayed in space and art and jewelry can be better combined. Hard gold also adopts advanced space dewaxing technology, without solder joints and seams, which makes hard gold jewelry more vivid. Therefore, there are various styles of hard gold jewelry, and the combination of hard gold and enamel makes hard gold jewelry colorful and more vivid.
