This belly ring is 316LVM surgical steel or PVD titanium! 316LVM surgical steel goes through a low carbon vacuum melting process to remove nickel. 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. The yellow gold and rose gold tones are Physical Vapour Deposition. PVD is more durable and therefore lasts longer than traditional plating. Gold PVD may cause a reaction. 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, it is recommended that metal alloy jewelry be cleaned often and not worn in moist/sweaty places. The stones are Austrian crystals. They're our favourite stones for a big reason: they never lose their sparkle. If you see it looking a bit dull, a quick clean bring the stone back to life.
