With the proper care, your Girls Crew jewelry can last a long time.

Sterling Silver Care: Sterling silver jewelry can be passed down from generation to generation with the right care. We encourage you to wear your silver everyday! Silver that is used regularly needs less care. In rare cases, silver can tarnish when it is exposed to salt, air, and products containing sulfur. But no need to worry, we offer cleaning services!

Gold Filled / Gold/Rose Gold Vermeil / Gold/Rose Gold/Rhodium Plated: We encourage you to remove your jewelry before showering, exercising and swimming. Gold Filled, Vermeil & Plated jewelry can tarnish when in contact with perfumes, lotions or hair products. Please avoid harsh chemicals such as bleach, oil, jewelry cleaners, or polishing cloths, this can affect the finishing. To help keep your jewelry looking beautiful, store it in a Girls Crew dust bag, sealed plastic bag or dry cloth bag.

Piercing Style Earrings - Surgical Steel with Gold Plated over Brass Pendant: These earrings have a surgical steel post and ball backing making it perfect for those with mild skin sensitivity. Please note that the pendant is 18k gold, 18k rose gold, or rhodium plated over brass and can cause slight irritation for those with moderate or very sensitive skin. Please remove before showering, swimming, working out, etc. Read the recommendations above for plated jewelry for more info. 

Solid Gold: Solid gold (10k, 14k gold) is a precious metal that will not oxidize or discolor since it is the least reactive metal. The 14k alloy gives our pieces their beautiful, subtle hue. It is also an active lifestyle’s best friend; it scratches less and doesn’t bend or wear out as easily as 18k.

  • Even something as strong as 14k solid gold deserves some loving. To maintain its beauty, scrub lightly with a toothbrush and warm water.

It was really useful in measuring my ring size, and its size makes it extremely versatile. I've never measured my fingers before this, so now I feel a lot better about buying rings in general because I know my size.

Perfect Ring Sizer

I chose to buy this item because I do not know what the ring size is of most of my fingers. I'm so glad I bought this because I can now buy more rings! I really like how easy this is to use.


Love this so much!

Thank you for carrying this kind of item! The sizing is spot on, and it’s very comfortable and easy to use!
