Beautiful Craftsmanship

I cannot express how excited I am about my beautiful ring. It is exactly as anticipated. I ordered a small (4.25) thin (3mm) hammered edge band, with a comfort edge.

The customer service was excellent! Shipping was fast. I love buying from small businesses, but the level of detail and amazing customer contact was phenomenal!

Wonderful creative design

I LOVE my ring!!! It is so beautiful- bright silver with the awesome pattern would like to get two more narrow ones to wear with it!!

Perfect tiny stud earrings

Exactly what I wanted: grey (my favorite color) diamonds set in platinum (hypoallergenic), lightweight for every day. Thank you!
