Yes, usually.  We make them hypoallergenic, meaning relatively unlikely to cause an allergic reaction.  We do this by using surgical steel posts - the same metal used in surgeries to prevent body rejection.You may see on some of our earrings no gold on the posts.  This is done to prevent the possibility of any reaction for those who are super sensitive to even 14K gold.  Our earrings are hypoallergenic but for that less than 1% who may react, you may always send them back for a refund.
