Precious, fine vintage & period jewelry...

I’ve been looking for estate pearls for about two years but was never able to commit until I saw these. I’m so glad I did— they are absolutely gorgeous. Brooke finds the most beautiful and interesting estate pieces and offers the very best customer service. No reason for me to shop for jewelry anywhere else!

This is my second purchase from Brooke. She’s responsive, helpful and knowledgeable. In short, her customer service is outstanding! And the item purchased arrived promptly, and it’s as described. My overall experience with this shop exceeded expectations. Thanks, Brooke!

I’m speechless, it’s just so beautiful everything I was hoping for and more. The quality is great, diamonds are shiny and clean. Brooke is great from answering question,to quick shipping, beautiful wrapping and special note. This is not my first purchase from Brooke, I recommend her store without any hesitation. I’ll definitely be back. Thank very much❤️

Very much appreciated the simplicity and efficiency of this site. This is my first purchase. LOVE LOVE LOVE these earrings. For the price they are beautiful!! Why spend thousands & thousands of dollars on earrings when you can get beautiful one's like these! The earrings are beautiful and look wonderful. The setting on these earrings is perfect. The color of the diamonds are very clear and bright. Highly recommend these. Thank you so much and God Bless You.

Absolutely Beautiful! I love everything about this ring. Pictures true to size. Perfect condition. Thank you so much!
