These list copper as a material used, maybe that part is the basket that holds the gem. The post is stamped with 925 sterling silver as is the butterfly backs which makes these great for most sensitive ears except those allergic to silver or copper. The CZ gem is medium in size there might be room for a tiny accent earring if you have multiple piercings but they would be best worn alone. These can be worn with semi-casual, dressy outfits, and office attire.Take off before swimming, bathing, working out, and applying perfume, body spray, cologne, lotion, sunblock, hairspray, insect repellents, and similar chemicals that can cause corrosion and damage to CZ gems. Wipe down with a soft damp or dry cloth after each use. When these are dirty you can clean them with mild soap, water, a soft toothbrush, scrub, rinse, and dry with a soft cloth ASAP. Do not let these soak in any liquids or cleansers.These studs would make a nice birthday gift, Christmas, Valentine's Day, Date night, prom night, and many other special occasions. They are priced for average studs of this nature, fairly and affordable.The amethyst color "purple" is fairly close to what you would find in nature an excellent imitation. The ornate detailing of claw clasps is an interesting unique touch, I may be back for the black pair later, and are on my wish list.The only negative is that there could be copper used in the basket, which lowers the quality so in this case wear them with care and treat them like costume jewelry and they will last for years.

Sehr schön verarbeitet, gefallen mir sehr gut. Bin zwar kein Mann, aber trage sie trotzdem, denn sie passen wunderbar zu meinen schwarzen Titankugelohrsteckern.👍👍👍

These earrings are stunning. I have yet to wear them. I hope my ear doesn't break out in a rash

- Assez discrètes, mais la taille reste convenable, pour ne pas les perdre facilement.Elles sont très mignonnes et on peut les porter dans diverses occasions, voir même tous les jours, avec différents styles vestimentaires.- C est un produit, présenté comme mixte, mais je trouve qu'elles font plutôt la gent féminine.- Matière en argent 925, et le rapport qualité prix reste abordable, oui je recommande ce produit sans problème.

Elles vont très bien avec mon style de tous les jours.Ellessont élégants et discrets à la fois.Une bonne idée de cadeau par exemple.Excellent rapport qualité prix!
