These are lovely earrings but unfortunately my wife’s sensitive ears reacted to them. Not sure if this means she is sensitive to titanium or that the earrings are not pure titanium. I notified Boccia and they promptly and kindly responded that we can return the earrings for a refund. Also note that these are typical studs with larger posts. 5 stars if it weren’t for my wife’s reaction. 5 stars for Boccia’s customer service and a thank you to Sherri.
