This process sucks the nickel from the metal. Nickel is one of the most common causes of metal allergies. Please note: this process cannot remove all the nickel. As a result, a very small amount of people react to 316LVM surgical steel. If this is you, we recommend checking out our titanium body jewelry. Otherwise, 316LVM surgical steel is an excellent choice for those with metal allergies. The charm is a metal alloy, which is ideal for casting and makes them perfect for jewelry with fine details. Many people have sensitivities to these alloys and may react. Metal Alloys with a PVD coating can help negate this reaction, but they may still irritate those with the strongest sensitivities. To avoid turning green, metal alloy jewelry is recommended to be cleaned often and not worn in moist/sweaty places. The stones are Austrian crystals. We love Austrian crystals they don't lose their sparkle like other similar stones. If your crystals start looking dull, a quick clean will bring them back to life.
