Mu Yin Sterling Silver Jewelry - Precious Metal Authentication Certificate

Mu Yin sterling silver jewelry undergoes sampling and authentication for *each production batch*. *Each production batch* refers to finished products from the same batch of silver material and production line, which may include different styles. - - - - - - - - - - - - - - - - - - - - - - Precious metal authentication is expensive in Taiwan. Very few sellers can provide **"domestic"** certificates! Or perhaps none at all! Why are there no Taiwanese certificates? Because they dare not authenticate! Why are mainland certificates untrustworthy? A one-on-one certificate costs only NT$20... make your own judgment. Moreover, many use photocopies or all-English fake international certificates. **"If any comments or implications of non-sterling silver are left in reviews,** **Mu Yin reserves the right to take legal action to protect its reputation and seek damages!"** I hope customers will not judge based on their own feelings. Entrust quality to professional and impartial appraisal institutions. 【Entrusted Appraisal Unit】 **"Taiwan United Gemological Institute" - Director Lin Shu-Hong, an authority in appraisal.** 【International Standard 925 Silver】 Pure silver is soft and easily deformed when made into jewelry. Therefore, adding other metals to pure silver to increase hardness is a formula used by international big brands. 92.5% silver is a recognized perfect ratio. Sterling silver with this proportion has moderate hardness and is the internationally recognized standard for silver jewelry. 【925 Silver Pricing】 Silver, like gold and platinum, has an international market price. Due to the pandemic, the prices of precious metal raw materials have all increased. Costs include: silver material + manufacturing cost (sampling, modeling, production) + platform transaction fee of 15% (shipping deducted) + platform handling fee + packaging + free shipping offer... Brands also need profit. Please buyers exercise their own judgment regarding excessively low-priced silver jewelry. 【Authentication Certificate】 https://live.staticflickr.com/65535/50429349703_5f881ebfbc_b.jpg https://live.staticflickr.com/65535/50363552662_a9157f9742_b.jpg https://live.staticflickr.com/65535/50362749178_58c7d7bca1_b.jpg https://live.staticflickr.com/65535/50366350206_6fccb3201a_b.jpg Chain: 鍊條 https://live.staticflickr.com/65535/50335873088_b7923124f0_c.jpg | Q&A | The following content is written by the designer. Please do not copy. Infringement will be prosecuted! The following maintenance methods are only applicable to **pure silver jewelry without electroplating or gemstones**. Q: How to distinguish real from fake silver jewelry? If the outer layer of silver jewelry is sanded, and it's milky white, is it pure silver? A: 1. Only by sending it for appraisal can you know the true silver content, and it must be a domestic appraisal certificate, not a mainland one. 2. Not necessarily. If the silver content is only 30-60%, and the rest is lead-tin-zinc alloy, sanding off the outer layer will also make it appear milky white or silvery white. Q: Does the 925 stamp mean it's pure silver? A: Absolutely not. Cheap alloys can have the 925 character added during mold making, and the finished product will have 925. However, for genuine sterling silver designs, the 925 mark is sometimes omitted for aesthetic reasons. Q: Why does my jewelry become dull and gray after wearing it for a few hours? A: Everyone's body chemistry is different. If your sweat contains more sulfides, it will easily cause silver jewelry to become dim, yellow, and black. If your skin has more oil, the more you wear it, the brighter it will become! Q: Why does it turn yellow or black after being stored for a while? How to prevent it? A: Silver is less stable than gold and easily reacts with sulfides in the air, forming silver sulfide on the surface of the silver jewelry, causing it to become dim, yellow, or dark gray. When not wearing it, please store it in the original sealed zipper bag to slow down the oxidation of the silver jewelry. Q: How to clean yellowed or blackened silver jewelry? A: 1. The simplest method is to use a silver polishing cloth. 2. Use traditional white paste toothpaste, lather it with your hands, and scrub with a toothbrush, then rinse with clean water and dry. 3. Use silver cleaning liquid. Immerse the silver jewelry in silver cleaning liquid for 5-10 seconds, then rinse with water to make it look new. Q: Why can't I remove the tarnish with a silver polishing cloth? A: You need to apply a little pressure (not brute force) when using a silver polishing cloth for it to be effective! If the quality of the silver polishing cloth is poor, its de-oxidation effect will also be poor. Mu Yin has ordered a new batch of effective silver polishing cloths, which will be provided to buyers. Q: What precautions should be taken when using silver cleaning liquid? A: Immerse the silver jewelry in silver cleaning liquid for 10-20 seconds, then rinse with water. Soaking for too long can corrode the surface, making it more prone to oxidation in the future. Also, the silver cleaning liquid the designer bought online for NT$39 was ineffective even after soaking for 2 minutes, because some silver cleaning liquids are diluted or have poor formulations, resulting in very poor effects. It is strongly recommended to use the silver cleaning liquid from the **British brand TOWN TALK** (beware of counterfeits). This brand's silver cleaning liquid makes jewelry bright white in 10 seconds without damaging the silver. Cheap ones require long soaking with no effect. If you cannot clean it yourself, you can mail it back to the studio for processing (you only need to bear the round-trip postage). https://live.staticflickr.com/65535/50332545951_94f2d3e028_c.jpg All sterling silver jewelry without white gold plating will oxidize and discolor. These are silver ornaments the designer is preparing for cleaning. It includes Pandora brand items; even the best silver jewelry will turn yellow and black! https://live.staticflickr.com/65535/50085270958_eedec083af_c.jpg
