A husband and wife team
Astra Jewelers is the two of us, Eddie and Stephanie, a husband and wife team. When you visit, you talk to one of us directly. Never a rotation of sales staff, never a stranger picking up where someone else left off. We keep the studio private and appointment based because choosing jewelry is personal. Personal things deserve quiet.
Every piece in our cases was picked by one of us. And when we make something custom, it is drawn around you, your hand, your stone, your story, so the finished piece could never have belonged to anyone else.
