If your items turn immediately, it can be caused by a metal-to-skin oil reaction. Each persons oils can make each metal react differently. We are not responsible for your skins reaction to metal or vise versa. Feel free to use a mild jewelry cleaner on 14K Gold, & Gold Filled jewelry. Stainless Steel & Gold Plated jewelry will turn naturally over time, but there's no way to reverse this.  Oxidation is not a manufacturing defect or fault.
Some factors that cause jewelry to oxidize and turn black or discolor :
An individual’s body acid. Your jewelry may be at a higher or earlier risk if you enjoy drinking or eating foods that are high in acid like; coffee, wine, fruit juices, oranges, tomatoes, vinegar, pickles, etc. Read more at the high acidic foods list.
Prescription drugs. Certain medications like anti-depressants, sulfa drugs, some antibiotics or even multivitamins can interact with or change a person’s body chemistry.
Cleaning products and chemicals. Direct contact with bleach, ammonia, acid, alcohol, chlorine, etc. will cause a chemical reaction to the metals of jewelry.
Menopause. Woman in menopause can experience body chemistry and hormonal changes that make oxidation more possible while their body adjusting.
Extremely moist skin. Some people can have physiological or metabolic states that stimulate excess moisture and perspiration (sweat) even without purposeful exercising. Especially moist skin can interact with the 7.5% metals with a green skin staining.
Everyone's skin type is different. Some people have strong reactions to bronze, nickel & gold plating. If you are susceptible to this, please avoid buying non-solid gold or sterling silver jewelry. We do not offer refunds or returns for this reason. We apologize in advance.
