Responsive seller, easy to work with. Ruby is as listed and looks even better than a photo can show. Delivery was swift and received before Christmas. Highly recommended shop. Thank you.

My wife LOVED these earrings and hasn’t taken them out since she received them weeks ago. I was also very impressed with the way they were shipped and the great care that went into it. It felt like I was receiving a package from a friend; not a stranger I bought something from on the internet. Thanks so much. These earrings are cherished and they really are well made.
