Franklin County's
Unique Fine Jewelry Store


At Mainestone Jewelry we specialize in the finest quality Maine Tourmaline. Our collections of beautifully designed jewelry are fabricated in gold and silver, and set with rich and vibrant gemstones to suit your personal style. We have a policy of excluding synthetic or commercial grade stones from our jewelry designs - all of our stones are natural.

We strive to offer you not just locally mined Maine gems, and traditional stones, but also the out-of-the-ordinary from around the world. The finest quality loose stones in all sizes and price ranges are offered and can be set in any design, both custom and traditional. High standards of craftsmanship are applied to each piece of jewelry, so that it brings years of carefree enjoyment, and will be treasured as an heirloom for generations to come.

We pay meticulous attention to detail when repairing your jewelry, whether it is a significant piece or a sentimental memento. All of our work is completed at our store. Our new LaserStar laser welder “Zelda” offers the latest in jewelry repair technology.

We would like to thank all of our customers, both near and far, for supporting us since we first opened our doors in 1990.

Come visit us at Mainestone for a unique shopping experience, we look forward to meeting you soon!
