1 thought on “S925 Diamond ring is silver or platinum”
Crystal
S925 is silver, and S is the abbreviation of English Silver, indicating that the content of silver is 92.5%. Internationally recognized silver jewelry, generally marks on S925, 925. Different from sterling silver, the brightness and luster of the S925 are closer to platinum, and the hardness is better than the sterling silver, so it is widely used in silver jewelry. This jewelry will turn dark due to chemical reactions, and S925 is treated with special processes, and the nature will be improved. This expansion information: How to distinguish silver and platinum Visidation methods: Tags: Each piece of jewelry should be engraved with chemical ingredients, such as (PT900) (PT750).签，均是铂金饰品颜色：铂金呈锡白色，即白中带灰，光泽灿烂rn仪器检测：试硬度：铂金的硬度为4--4.5度，比金、银硬，用小刀或The glass scrape is scratched, but it will not be scratched by the nails scratching and testing density: the density of platinum is extremely large, and the hand is sinking. The test density of the static water mechanics should be 21.43g/cm cubic cubic fire burning: the melting point of platinum is as high as 1773 Degree, burn platinum on the alcohol lamp or electric furnace. Test: Take a little platinum powder, placed in a hydroxide bottle, and the hydrogen peroxide immediately produces air bubbles. The platinum after the response is not damaged. You can use . Platinum has a heavy feeling, heavier than gold (19.36), heavier than K platinum, and heavier than silver (10.45). The melting method: Platinum melting point reaches 1773OC, which is much higher than K platinum and silver. Generally, the welding gun cannot melt the platinum, and it can be identified to the authenticity. And platinum is unchanged after cooling. mades: Platinum jewelry has a standard poke. Internationally use PT or PT, such as PT950 platinum color is 950 %. The natural method of gas: Put the jewelry on the twisting gas stove, put it on a few minutes. If the jewelry becomes red and warmed up the gas stove, it is a platinum product. This is because platinum can be used as a catalyst, which prompts the gas and air to oxidize the heat in the air, so that the platinum is warmed, red, and can ignite the gas. The test method: A will wipe the mercury on platinum. Platinum will not be polluted, while gold and silver will be contaminated with mercury. B is placed in a hydraulic bottle in the edge or middle depression of platinum jewelry in the depression of the platinum jewelry. Platinum can be used as a catalyst to promote hypoxic decomposition, and the oxygen is released up and down. The platinum jewelry usually shows the texture of the jewelry with thousands of points, and it is also one of the basis for jewelry pricing. The weight: The proportion of platinum is 21.4, and the proportion of silver is 10.49. The same volume of platinum is doubled than silver. Generally, the weight of the hand can be divided into two. The appearance and hardness comparison: Platinum with the naked eye carefully observed will be slightly gray and white, the texture is hard, and it is difficult to scratch with a large head needle. Smooth and delicate, light oxidation will become gray -white or black black. Its Mo's hardness is 2.7, which is much softer than platinum. The fire burning method: Platinum can resist high temperature oxidation, its melting point is as high as 1770_c, and the fire is burned with average high temperature (gasoline) fire. After cooling, the color does not change or traces of quenching. The silver melting point is low. After the high temperature is burned, the color content is red, the color is red, black, or black. The chemical method: The chemical properties of platinum are extremely stable, resistant to corrosion, and can not be reflected in any acid or alkali, while silver is not resistant to strong acid corrosion.
