❓ Frequently Asked Questions
Q1: Are these earrings suitable for sensitive ears?
Yes, 925 sterling silver is generally hypoallergenic and suitable for most people with sensitive ears. Sterling silver is a precious metal that’s gentle on skin. However, if you have extremely sensitive ears or metal allergies, you may want to consult with your healthcare provider before wearing.
Q2: What is the September birthstone color?
The traditional September birthstone is sapphire, featuring deep blue tones ranging from light blue to rich royal blue. These CZ 4mm studs capture the beautiful sapphire color — a deep, romantic blue that evokes the ocean and night sky. Sapphire is believed to bring wisdom, loyalty, and nobility to the wearer.
Q3: Will sterling silver tarnish over time?
Sterling silver can develop a natural patina or slight tarnish over time when exposed to air and moisture. This is normal and easily remedied with a silver polishing cloth. Regular cleaning and proper storage in a dry place or anti-tarnish pouch will keep your earrings looking brilliant for years.
Q4: What’s the difference between 4mm and 5mm studs?
4mm studs are more petite and subtle — perfect for minimalist jewelry lovers, everyday wear, sleeping, and layering. 5mm studs are slightly more noticeable while still being appropriate for daily wear.
