FAQs

Q: Are your brass jewelry hypoallergenic?
A:Our brass jewelry may contain naturally occurring trace amounts of lead and nickel that are within international safe standards.
While most people can wear them comfortably, those with extremely sensitive skin may consider wearing them for shorter periods.

Q: Will brass jewelry tarnish or turn skin green?
A: Brass naturally oxidizes over time, but we apply an anti-tarnish coating to slow this process.

Q: How long does brass jewelry last?
A: With proper care, brass jewelry can last for years. The color and finish remain beautiful with regular maintenance.

Q: Can I wear brass jewelry in the shower or swimming?
A: We recommend removing it before showering, swimming, or exercising. Water, sweat, and chemicals can speed up tarnishing and damage the finish.

Q: How do I clean and maintain brass jewelry?
A: - Gently wipe with a soft dry cloth after each wear.
- Use a brass polish or a mix of lemon juice + salt for heavy tarnish.
- Store in a dry, airtight pouch or jewelry box.
- Avoid contact with perfume, lotion, and harsh chemicals.

Q: Do you use plating on your brass jewelry?
A: Many styles are finished with 18K gold, silver or rose gold plating for extra shine and protection.

Q: Will the plating fade?
A: Plating may wear gradually with frequent use, but our durable plating ensures long-lasting color. Avoid friction & chemicals to extend its life.

Q: Are your rings/bracelets adjustable?
A: Most of our rings and bracelets are adjustable to fit most sizes. Specific measurements are listed on each product page.

Q: Do you accept wholesale or custom orders?
A: Yes! We welcome wholesale, bulk, OEM, and custom orders (logo engraving, custom designs, custom plating). Contact us for details.

FAQs

Q: Are your S925 silver jewelry nickel-free and hypoallergenic?
A: Yes. Our S925 sterling silver jewelry is made with nickel-free alloys, making it safe and suitable for most people with sensitive skin. It is hypoallergenic and unlikely to cause irritation or allergic reactions.

Q: Will S925 silver jewelry tarnish or turn skin green?
A: S925 silver can naturally tarnish over time due to exposure to air, moisture, sweat, or chemicals. This is normal and easy to clean with a silver polishing cloth. It will not turn skin green like some brass or plated metals may do.

Q: How long does S925 silver jewelry last?
A: With proper care, S925 sterling silver jewelry can last for many years, even a lifetime. The metal is durable and maintains its shine with regular cleaning and maintenance.

Q: Can I wear S925 silver jewelry in the shower, swimming, or while exercising?
A: We recommend removing S925 silver jewelry before showering, swimming, exercising, or using hot tubs. Water, chlorine, sweat, and chemicals in soaps/lotions can speed up tarnishing and damage the finish over time.

Q: How do I clean and maintain my S925 silver jewelry?
A: - Use a silver polishing cloth to gently remove tarnish.
- For deeper cleaning, use a mild silver cleaner designed for sterling silver.
- Store in a dry, airtight jewelry pouch or box to slow tarnishing.
- Avoid contact with perfume, hairspray, lotion, and harsh chemicals.

Q: Do your S925 silver jewelry come with plating?
A: Many of our styles are finished with rhodium plating to enhance shine, prevent tarnish, and match a bright silver appearance. Some styles may also feature gold or rose gold plating over sterling silver.

Q: Will the plating on S925 silver jewelry fade?
A: Plating may wear off gradually with frequent use, especially on areas that experience friction. To extend its life, avoid contact with chemicals, excessive moisture, and store the jewelry separately.

Q: Are your S925 silver rings/bracelets adjustable?
A: Many of our rings and bracelets are adjustable to fit most sizes. Specific measurements and size details are listed on each product page for your reference.

Q: Do you offer custom or wholesale orders for S925 silver jewelry?
A: Yes! We welcome wholesale, bulk, OEM, and custom orders for S925 silver jewelry, including logo engraving, custom designs, and personalized plating options. Contact us for more details.
