    jewelry wholesale manufacturers The jewelry of "G750" refers to a kind of jewelry composed of 750 gold content of 999, that is, 75%gold plus 25%of other metal alloys (such as silver, tadpoles, zinc, nickel, etc.).
    g750 gold jewelry not only has the precious value of gold, but also has the advantages of strong proportion of components, strong ductility, high hardness, and variety of color. It can be used in jewelry design to fully exert complex and exquisite creative performance.
    In the trend of the world's jewelry, K gold is the mainstream, and Western fashion people even use the unique and unique K gold jewelry to highlight their personal style.
    is because K gold fashion can always meet the needs of contemporary young people, so the status of the fashion industry has been lasting, forming a popular style of wearing K gold jewelry.

    The expansion information:
    g750 Identification:
    1, fake G750 gold is far lower than real gold, and it is obviously lacking weight with hand; Gold craftsmanship, the structure is slightly rough, the gloss is not bright, and the connection is large. If you look closely, you can see the golden skin that wants to fall off. The old goods can be visible to the signs of color, the real G750 gold process is delicate and shiny; Tag steel printing, the real G750 (18K) gold product is engraved with the steel printing of G18K, 18K or G750, and the label is called G750 (18K) gold or G750 platinum; the fake 18K gold steel print is G750GP or G750GF, etc. The label is called alloy or G750 (18K (18K (18K ) Casting gold et al.;
    4, from the point of view of the purchase, the real G750 gold is real gold, which must be sold by the gold sales unit approved by the People's Bank of China;
    5. Seeing after -sales service, fake G750 gold cannot be repaired Welding can be thrown away if the color is broken; the real G750 gold can be repaired and polished, and it can be repaired if it is accidentally broken. Other styles can be processed.

    tipi brand jewelry wholesale Palladium is not a new type of precious metal. As early as 1803, British chemist Vallaston was separated from rough platinum. It is widely used in various industries, but the consumption of platinum is not high.

    In the classification of minerals, the platinum elements are natural platinum sub -groups, including natural element minerals such as 铱, 铑, 钯, and platinum. They exist in extension of classification and replacement in each other, thereby forming a series of types of quality mixed crystals. The physical and chemical properties between these elements have great similarities.

    钯 钯 often accompanied each other with platinum, and the output is less than platinum. Its appearance (color, gloss) is very similar to platinum, insoluble in organic acid, cold sulfuric acid or hydrochloric acid, but soluble in nitric acid and king water. It is not easy to oxidize and loses luster at room temperature. The temperature will produce oxidation about 400 degrees, but the temperature will rise to 900 degrees. The density of 体 (unit volume weight) is light than platinum, strong ductility, and is slightly harder than platinum, but it also needs to be mixed with other elements as jewelry to increase its hardness. The relative density is 12, and 21.35 is less than platinum. Therefore, the same style of jewelry, 钯 jewelry is far more light than platinum jewelry, and the unit price of today's units is also cheaper than platinum (historically, the price per gram is higher than the platinum of about $ 100 per gram. To.

    mine: According to international standards, the mark of precious metal jewelry should be hit on the jewelry. “Jewelry marks are" PD ", and the content of 钯 is expressed by purity thousands.
    The white gold

    , also known as K platinum, it is a alloy that is made after melting gold and other white metals. Its code WG (White Gold), which means white gold. White K gold jewelry is often expressed in "18K platinum" or "14K platinum". It is generally G18K or G750

    platinum (Platnum)

    symbol PT, silver gray white, a proportion of 21.35, melting point 170 ° C, Mohs hardness 4-4.5 degrees, stable chemical properties Except for the king water, it is not corroded by acid and alkali. Pure platinum is relatively soft, and adding metals such as 钌, 铑, and 钯 will increase its hardness.

    The platinum alloy

    The alloys of platinum and other metals, such as 钯, 铑, 钇, 钌, cobalt, copper, etc. Although pure platinum hardness is higher than gold, it is still inadequate as inlaid, and it must be used to make jewelry with other metal alloys. The label of platinum jewelry internationally is PT, PLAT or Platinum, and represented by a thousand points of purity. For example, PT900 means that the purity is 900 ‰. Common platinum jewelry is marked with PT1000, PT950, PT900, PT850.

    (Palladium)

    The members of Platinum, silver -white, symbol PD, light than platinum, strong ductility, slightly harder than platinum, insoluble in organic acids in organic acid , Cold sulfuric acid or hydrochloric acid, but dissolved in nitric acid and Wang Shui. It is not easy to oxidize and loses luster in normal conditions. The jewelry industry is used alone, or it is used as a component of gold, silver, and platinum alloy to increase its hardness. Common gold, crickets, k golds, platinum, and cricket alloys on the market.

    CT refers to Carat-carat (the weight unit of diamond) 1ct = 0.2g 1ct = 100 points
