A Family Tradition In Fine Jewelry

Meet the Mason Family

Harold and Dorthea Mason, founders of Mason Jewelers
Our founders

Harold & Dorthea Mason

Harold went to watchmaker's school right after serving his country in the 50s. He originally had to take a hand engraving course before he was allowed to take the watch repair course at Bradley University in Elgin, IL.

He originally had a small watch bench set up in the back of a hardware store of his father in law's in the suburbs of St. Louis, MO, Matese Hardware. He worked hard every day to save up $500 to come back to his hometown (Greencastle) with his wife Dorthea to open up their jewelry store. This was in 1957.

In 1982 Harold and Dorthea opened up their second store in Plainfield. The Greencastle store has been run for years by their son Steve Mason who retired in 2025 and is now run by his daughter Becky (Mason) Burris. The Plainfield store is run by Harold and Dorthea's youngest son Scott and their grandson Anthony Mason.

The Maker's Philosophy

Every stone should have a point of view.

We do not simply pick stones because they are flawless on paper. We look for gems with a quirk, a flash of color, an unexpected inclusion, or a natural detail that speaks to where the stone came from and why it feels alive.

For our Greencastle and Plainfield neighbors, that means a more personal alternative to big-box jewelry. The pieces in our cases are chosen for proposals, anniversaries, milestones, and family stories, not just another transaction.

Greencastle & Plainfield, Indiana

Character Over Commodity

A meaningful jewel has presence. We seek pieces with texture, heritage, and individuality so the person wearing it feels connected to more than a price tag.

A Personal Connection

Jewelry is a personal, tactile experience that deserves a face-to-face connection.

That belief is why Mason Jewelers has intentionally moved away from online sales. A ring, watch, heirloom repair, or custom piece deserves conversation, careful handling, and the confidence that comes from looking your jeweler in the eye.

The Mason Standard is built around quality and security. Every heirloom is received, inspected, and cared for in our physical Indiana showrooms, away from the risks and impersonality of digital shipping.

Values & Sourcing

Small business standards with heirloom expectations.

Ethical Sourcing

We hold our diamonds and materials to responsible standards, working with trusted partners who support conflict-free sourcing and transparent practices.

Small Business, Big Heart

Native Hoosiers since 1957, we still believe jewelry carries a little magic. It marks who you love, where you have been, and what becomes part of who you are.

Heirloom Quality

We focus on timeless pieces with heart: jewelry chosen for life, cared for over time, and ready to be handed down when the next story begins.
