Tip: the size of your ear and the angle it was pierced at will change the size you need. Please measure carefully before ordering. 316LVM surgical steel goes through a process called low carbon vacuum melting. The process sucks the nickel out of the steel. Nickel is one of the most common causes of metal allergies. This process cannot remove 100% of nickel. As a result, a small number of people react to it. We recommend our anodized, blackline, or untreated titanium body jewelry if this is a concern for you. Otherwise, 316LVM surgical steel is a great option for people 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 because they never lose their sparkle. Other stones can get cloudy over time. If your Austrian crystal looks a bit dull, a quick clean will bring it back to life.
