Ring Sizing

Purchase this ring sizer to help determine your ring size. This sizing tool is most accurate for double band rings and bands 6mm and under.

Fingers can change size due to many circumstances. The best way to get an accurate size is to check the size a couple of different times throughout a several day period to determine your best size. The majority of our rings can be resized, but if the ring has a stone setting other than a diamond, it probably cannot be resized unless otherwise noted in the item listing.

Some of our rings with stones are shown with the stone not set in order for us to size the ring to your specifications and set the stone afterwards. This avoids damage to the stone during sizing. Reference the individual ring listings for more details. Wide bands 7mm and above have more friction against the finger and will need to be ordered a little larger.

Our double band rings fit like a narrow band. When getting sized for a double band ring, you can get sized for a ring that is narrow.

When getting your finger sized, inform jeweler of the width band you are intending on purchasing and rely on them to determine your ring size.

If you need a ring resized that you have already purchased please contact us. 

Looking for an Engagement Ring?

There are many sneaky options for getting the size right but the best way is to have their finger sized by a professional.

You may be able to sneak one of their rings and bring it into a jewelry store and ask them to check the size.

Beth Millner Jewelry has wish lists too, so they could come in to the store and fill out a wish list and we will try to get their ring size written down.


Among the rarest agates in the world, copper Lake Superior Agates are formed deep underground in the Northernmost reaches of Michigan's Upper Peninsula. This highly sought after and rare variety of the Lake Superior Agate has copper naturally occurring in the stone.

    Copper Agate Autumn Twig Ring - Choose Your Own Stone


    Wonderful work. Very happy clients and friends here!


    It is so gorgeous! I can't wait to add more to my collection! Thank you for creating such amazing pieces!

    My new Lake Superior Power ring

    This ring is perfect,..from the comfort and style of the band to the elegance of the copper agate. For the past 2 years I have had the privilege of working in the UP for my comany. I have been chosen for a next level management position, which means I will be downstate. I wanted somethng to remind me of the healing power of Lake Superior and the UP. This ring embodies it for me. The staff at Beth Millner are gracious and demostrate a very caring hospitality. Glad to be connected.

    Won't take it off!

    I got my ring 3 weeks ago, and it basically hasn't been off my finger since. Love, love, love this ring. I have big hands and the design is substantial enough not to be ridiculously out of scale — yet also, due to the openwork band, it still manages to look delicate, rather than clunky. The swirls in the agate are nicely complemented by the twig & leaf detailing (or vice versa). Plus, it goes beautifully with my wedding ring, so I can wear them on the same hand easily.


    This ring is stunning and very comfortable to wear. I love it!

    Beautiful artwork, killer challenging.

    Up for a test of your puzzling skills (and persistence)? This will do it. The artwork is gorgeous and intriguing. The black and white lower section will drive you batty. Took awhile, but great fun. (So, what's with the snow building up on the underside of most of the branches--is that an artsy thing?)

    Rose Gold and Silver Conifer Couple Ring

    I cannot find adequate words to describe the beauty of this ring. The contrast between the two metals is absolutely perfect, which only enhances the beauty and simplicity of the design. The craftsmanship is of the highest quality by Beth Millner and I look forward to further jewelry purchases. I also liked that I purchased this piece on sale.

    Communication with Beth via phone was very prompt and professional. I highly recommend a jewelry purchase from Beth Millner. Delivery was quick and packaging was outstanding. Thank you, Beth, for your beautiful ring creation.

    Beautiful print

    Print reminds me of wonderful trip to Lake Superior. Awesome power of the water is captured well in her print design.

    This is a hauntingly beautiful setting and zi had to have one of these prints.. The use of light and dark, the shading and shadows alldraw me into the forest. The Turquoise color illuminating a nighttime scene like this is something I would love to see. Now I can see Beth's print every day as it hangs on my wall andlose myself . Thank you! XOXO

    Love, love, love

    These earrings are so beautiful. Simple, yet stunning. Getting tons of compliments.
