Trusted brands, reputable brand selling jewelry, generally accompanied by inspection agency inspection certificate authority, when consumer choose and buy should pay attention to check.
4, when the choose and buy precious metals ornaments weight shall be carried out in a field survey, and found that the presence of measurement error.
The tourbillon – let watch time more accurate!
The tourbillon is Mr Louis breguet Swiss watch masters in 1795 invented a device clock speed. Breguet invented the tourbillon mechanism, it is to error correction gravity of clock parts. Ordinary mechanical watch, due to the spring firmness, metal fatigue and the influence of gravity, the error is bigger; The tourbillon governor, is currently the only can not affected by these years error less than 1 second, is the only mechanical level can reach the observatory the table structure. Today, almost all the materials and key spare parts table core can only be produced in Switzerland, completely native Switzerland the tourbillon watch movements, often more than one million yuan, loading the tourbillon movement mechanical watch also has always been the darling of the collectors, becomes the symbol of currency.
The originality of the tourbillon is that put escapement (Carriage) within a framework, the framework around cheap cartier bracelet the axis is the axis of the balance wheel do 360 – degree rotation. This way, the original escapement is fixed, so when the table aside position change, escapement, caused the escapement force error resulting from the different parts; When escapement continuously spin 360 degrees, will be part of the azimuth error together, offset each other, so as to eliminate the error. At present the tourbillon is usually 1 minute to turn 360 degrees, which is the most ideal rotation speed.
“A lot of famous brand diamond ring is in a small factory processing, bid ten thousand diamond ring, cost less than three thousand”, recently, the diamond of the storm in this discussion is only a microcosm in the field of jewelry. On the interview in dalian city jewelry association and international diamond appraiser Xiong Xianzheng Mr Learned that at present our country inspection certification bodies hundreds of diamonds, the good and bad are intermingled of qualification, this is a dramatic increase profits of diamonds and gold and silver jewelry industry one of the main factors.
Dalian in dalian market, currently in gold jewelry has two agencies, the testing market is relatively specification. Now dalian market, however, much as the other brands, they tend to test in the field, and field testing institutions is numerous, the good and evil people mixed up. The personage inside course of study says, the field some examination organization in order to attract customers, launched ultra low-cost detection, jewelry manufacturing enterprises know about these examination organization ability, but considering the cost, and don’t know much about consumers’ identification, they turn a blind eye, even spend money on appraisal report.
Aiming at the problem of the jewelry appraisal certificate of the good and bad are intermingled, Xiong Xianzheng suggest consumers to buy diamonds, when buying a diamond jewelry to GIA standard HeGuoJian testing certification certificate shall prevail, carefully check the laser on the diamond size is consistent with the number on the certificate.
What is platinum and platinum, K knockoff cartier bracelet 18k gold platinum and palladium?
In recent years, very popular use silver precious metal jewelry hallow. In business, the names of these precious metals are often confused.
In Taiwan, with platinum, K Bai Jinlai call these white metal (silver not discuss here). In fact this is often misleading and confusion, we must according to the chemical elements of the periodic table named to explain, to get a reasonable title.
A, White gold, White gold) :
On the market of the so-called K white gold, platinum, in fact it is a gold, nickel, copper, zinc alloy. Or gold and silver, or gold, silver and copper alloy. Also including Taiwan master often use of gold and palladium alloy. Its code WG (White Gold), which is the meaning of White Gold. Early in 226 gold (6, 2, palladium and copper (2) to represent contains 600/1000 of the pure white gold, also known as “material”, means with gold and silver metal, rather than do not contain nickel alloy of gold (nickle alloy) plating. General foreign stamps are commonly used; WG585 (14 k), WG750 (18 k) or just Numbers represent value. Have good reflective white gold, and not easy to lose luster, extensive use of before in the future of the platinum and palladium, white gold as the main to set stone jewelry hallow silvery white metal.
Second, platinum (platinum) :
Also known as white gold, is or true platinum. But the call is not reasonable, and easily confused with white gold. Its symbol is the Pt, silver grey white, specific gravity 21.35, melting point 1700 ℃, mohs hardness 4-4.5 degrees, chemical stability, not affected by acid and alkali corrosion besides aqua regia.
Pure platinum is more soft, ruthenium, rhodium and palladium metal will increase its hardness. South American indians made platinum jewelry as early as before the 15th century, did not start until after the middle of the 19th century Europe, now Japan’s biggest consumer of platinum.
Three, platinum alloy (platinum alloy) :
Refers to the mixture of platinum and other metal alloy, such as with palladium, rhodium, yttrium, ruthenium, copper, cobalt, osmium, etc. Although platinum than high hardness, but it is not enough for the use of set hallow, necessary and other metal alloys, can be used to make jewelry.
Jewellery using platinum and platinum, iridium, ruthenium alloy is more. In Europe and Hong Kong using platinum, cobalt alloy in the casting. With platinum in Japan (85%), and palladium alloy smelting. Platinum is the stamp act the role of Pt, platt international or Platinum, and the purity of representative of QianFenShu word, such as Pt900 said purity is 900% o. In Japan, the specifications of the platinum jewelry Pt1000 are marked, Pt950 Pt900 Pt850.
Four, palladium (palladium) :
Is a member of the platinum, silver, Pd, the proportion of 12, lighter than platinum, good extension, a little hard than platinum, does not dissolve in the organic acid, sulfuric acid or hydrochloric acid. But soluble in nitric acid and aqua regia. Not easy oxidation and lose luster, under normal temperature about 400 ℃ can produce oxide surface, but when the temperature rise to 900 ℃ and restore luster. Now is much cheaper than platinum and palladium, jewelry industry used alone, or as part of the gold, silver, platinum alloy. Sometimes involved in some ruthenium, to increase its hardness. On the market the common gold, K gold and platinum, palladium and palladium alloy.
